en.wikipedia.org/wiki/Aswan_Dam
The Aswan Dam, or more specifically since the 1960s, the Aswan High Dam, is the world's largest embankment dam, which was built across the Nile in Aswan, Egypt, between 1960 and 1970. Its significance largely eclipsed the previous Aswan Low Dam initially completed in 1902 downstream. Based on the success of the Low Dam, then at its maximum utilization, construction of the High Dam became a key objective of the government following the Egyptian Revolution of 1952; with its ability to better control flooding, provide increased water storage for irrigation and generate hydroelectricity, the dam was seen as pivotal to Egypt's planned industrialization. Like the earlier implementation, the High Dam has had a significant effect on the economy and culture of Egypt.
Before the High Dam was built, even with the old dam in place, the annual flooding of the Nile during late summer had continued to pass largely unimpeded down the valley from its East African drainage basin. These floods brought high water with natural nutrients and minerals that annually enriched the fertile soil along its floodplain and delta; this predictability had made the Nile valley ideal for farming since ancient times. However, this natural flooding varied, since high-water years could destroy the whole crop, while low-water years could create widespread drought and consequently famine. Both these events had continued to occur periodically. As Egypt's population grew and technology increased, both a desire and the ability developed to completely control the flooding, and thus both protect and support farmland and its economically important cotton crop. With the greatly increased reservoir storage provided by the High Aswan Dam, the floods could be controlled and the water could be stored for later release over multiple years.
The Aswan Dam was designed by the Moscow-based Hydroproject Institute.
The earliest recorded attempt to build a dam near Aswan was in the 11th century, when the Arab polymath and engineer Ibn al-Haytham (known as Alhazen in the West) was summoned to Egypt by the Fatimid Caliph, Al-Hakim bi-Amr Allah, to regulate the flooding of the Nile, a task requiring an early attempt at an Aswan Dam. His field work convinced him of the impracticality of this scheme.
The British began construction of the first dam across the Nile in 1898. Construction lasted until 1902 and the dam was opened on 10 December 1902. The project was designed by Sir William Willcocks and involved several eminent engineers, including Sir Benjamin Baker and Sir John Aird, whose firm, John Aird & Co., was the main contractor.
In 1952, the Greek-Egyptian engineer Adrian Daninos began to develop the plan of the new Aswan Dam. Although the Low Dam was almost overtopped in 1946, the government of King Farouk showed no interest in Daninos's plans. Instead the Nile Valley Plan by the British hydrologist Harold Edwin Hurst was favored, which proposed to store water in Sudan and Ethiopia, where evaporation is much lower. The Egyptian position changed completely after the overthrow of the monarchy, led by the Free Officers Movement including Gamal Abdel Nasser. The Free Officers were convinced that the Nile Waters had to be stored in Egypt for political reasons, and within two months, the plan of Daninos was accepted. Initially, both the United States and the USSR were interested in helping development of the dam. Complications ensued due to their rivalry during the Cold War, as well as growing intra-Arab tensions.
In 1955, Nasser was claiming to be the leader of Arab nationalism, in opposition to the traditional monarchies, especially the Hashemite Kingdom of Iraq following its signing of the 1955 Baghdad Pact. At that time the U.S. feared that communism would spread to the Middle East, and it saw Nasser as a natural leader of an anticommunist procapitalist Arab League. America and the United Kingdom offered to help finance construction of the High Dam, with a loan of $270 million, in return for Nasser's leadership in resolving the Arab-Israeli conflict. While opposed to communism, capitalism, and imperialism, Nasser identified as a tactical neutralist, and sought to work with both the U.S. and the USSR for Egyptian and Arab benefit.[8] After the UN criticized a raid by Israel against Egyptian forces in Gaza in 1955, Nasser realized that he could not portray himself as the leader of pan-Arab nationalism if he could not defend his country militarily against Israel. In addition to his development plans, he looked to quickly modernize his military, and he turned first to the U.S. for aid.
American Secretary of State John Foster Dulles and President Dwight Eisenhower told Nasser that the U.S. would supply him with weapons only if they were used for defensive purposes and if he accepted American military personnel for supervision and training. Nasser did not accept these conditions, and consulted the USSR for support.
Although Dulles believed that Nasser was only bluffing and that the USSR would not aid Nasser, he was wrong: the USSR promised Nasser a quantity of arms in exchange for a deferred payment of Egyptian grain and cotton. On 27 September 1955, Nasser announced an arms deal, with Czechoslovakia acting as a middleman for the Soviet support. Instead of attacking Nasser for turning to the Soviets, Dulles sought to improve relations with him. In December 1955, the US and the UK pledged $56 and $14 million, respectively, toward construction of the High Aswan Dam.
Though the Czech arms deal created an incentive for the US to invest at Aswan, the UK cited the deal as a reason for repealing its promise of dam funds. Dulles was angered more by Nasser's diplomatic recognition of China, which was in direct conflict with Dulles's policy of containment of communism.
Several other factors contributed to the US deciding to withdraw its offer of funding for the dam. Dulles believed that the USSR would not fulfil its commitment of military aid. He was also irritated by Nasser's neutrality and attempts to play both sides of the Cold War. At the time, other Western allies in the Middle East, including Turkey and Iraq, were resentful that Egypt, a persistently neutral country, was being offered so much aid.
In June 1956, the Soviets offered Nasser $1.12 billion at 2% interest for the construction of the dam. On 19 July the U.S. State Department announced that American financial assistance for the High Dam was "not feasible in present circumstances."
On 26 July 1956, with wide Egyptian acclaim, Nasser announced the nationalization of the Suez Canal that included fair compensation for the former owners. Nasser planned on the revenues generated by the canal to help fund construction of the High Dam. When the Suez War broke out, the United Kingdom, France, and Israel seized the canal and the Sinai. But pressure from the U.S. and the USSR at the United Nations and elsewhere forced them to withdraw.
In 1958, the USSR proceeded to provide support for the High Dam project.
In the 1950s, archaeologists began raising concerns that several major historical sites, including the famous temple of Abu Simbel were about to be submerged by waters collected behind the dam. A rescue operation began in 1960 under UNESCO
Despite its size, the Aswan project has not materially hurt the Egyptian balance of payments. The three Soviet credits covered virtually all of the project's foreign exchange requirements, including the cost of technical services, imported power generating and transmission equipment and some imported equipment for land reclamation. Egypt was not seriously burdened by payments on the credits, most of which were extended for 12 years with interest at the very low rate of 2-1/2%. Repayments to the USSR constituted only a small net drain during the first half of the 1960s, and increased export earnings derived from crops grown on newly reclaimed land have largely offset the modest debt service payments in recent years. During 1965–70, these export earnings amounted to an estimated $126 million, compared with debt service payments of $113 million.

The Soviets also provided technicians and heavy machinery. The enormous rock and clay dam was designed by the Soviet Hydroproject Institute along with some Egyptian engineers. 25,000 Egyptian engineers and workers contributed to the construction of the dams.
Originally designed by West German and French engineers in the early 1950s and slated for financing with Western credits, the Aswan High Dam became the USSR's largest and most famous foreign aid project after the United States, the United Kingdom, and the International Bank for Reconstruction and Development (IBRD) withdrew their support in 1956. The first Soviet loan of $100 million to cover construction of coffer dams for diversion of the Nile was extended in 1958. An additional $225 million was extended in 1960 to complete the dam and construct power-generating facilities, and subsequently about $100 million was made available for land reclamation. These credits of some $425 million covered only the foreign exchange costs of the project, including salaries of Soviet engineers who supervised the project and were responsible for the installation and testing of Soviet equipment. Actual construction, which began in 1960, was done by Egyptian companies on contract to the High Dam Authority, and all domestic costs were borne by the Egyptians. Egyptian participation in the venture has raised the construction industry's capacity and reputation significantly.
On the Egyptian side, the project was led by Osman Ahmed Osman's Arab Contractors. The relatively young Osman underbid his only competitor by one-half.
1960: Start of construction on 9 January
1964: First dam construction stage completed, reservoir started filling
1970: The High Dam, as-Sad al-'Aali, completed on 21 July[18]
1976: Reservoir reached capacity.
Specifications
The Aswan High Dam is 3,830 metres (12,570 ft) long, 980 m (3,220 ft) wide at the base, 40 m (130 ft) wide at the crest and 111 m (364 ft)[ tall. It contains 43,000,000 cubic metres (56,000,000 cu yd) of material. At maximum, 11,000 cubic metres per second (390,000 cu ft/s) of water can pass through the dam. There are further emergency spillways for an extra 5,000 cubic metres per second (180,000 cu ft/s), and the Toshka Canal links the reservoir to the Toshka Depression. The reservoir, named Lake Nasser, is 500 km (310 mi) long[20] and 35 km (22 mi) at its widest, with a surface area of 5,250 square kilometres (2,030 sq mi). It holds 132 cubic kilometres (1.73×1011 cu yd) of water.
Due to the absence of appreciable rainfall, Egypt's agriculture depends entirely on irrigation. With irrigation, two crops per year can be produced, except for sugar cane which has a growing period of almost one year.
The high dam at Aswan releases, on average, 55 cubic kilometres (45,000,000 acre⋅ft) water per year, of which some 46 cubic kilometres (37,000,000 acre⋅ft) are diverted into the irrigation canals.
In the Nile valley and delta, almost 336,000 square kilometres (130,000 sq mi) benefit from these waters producing on average 1.8 crops per year. The annual crop consumptive use of water is about 38 cubic kilometres (31,000,000 acre⋅ft). Hence, the overall irrigation efficiency is 38/46 = 0.826 or 83%. This is a relatively high irrigation efficiency. The field irrigation efficiencies are much less, but the losses are reused downstream. This continuous reuse accounts for the high overall efficiency.
The following table shows the distribution of irrigation water over the branch canals taking off from the one main irrigation canal, the Mansuriya Canal near Giza.

The salt concentration of the water in the Aswan reservoir is about 0.25 kilograms per cubic metre (0.42 lb/cu yd), a very low salinity level. At an annual inflow of 55 cubic kilometres (45,000,000 acre⋅ft), the annual salt influx reaches 14 million tons. The average salt concentration of the drainage water evacuated into the sea and the coastal lakes is 2.7 kilograms per cubic metre (4.6 lb/cu yd). At an annual discharge of 10 cubic kilometres (2.4 cu mi) (not counting the 2 kilograms per cubic metre [3.4 lb/cu yd] of salt intrusion from the sea and the lakes, see figure "Water balances"), the annual salt export reaches 27 million ton. In 1995, the output of salt was higher than the influx, and Egypt's agricultural lands were desalinizing. Part of this could be due to the large number of subsurface drainage projects executed in the last decades to control the water table and soil salinity.
Drainage through subsurface drains and drainage channels is essential to prevent a deterioration of crop yields from waterlogging and soil salinization caused by irrigation. By 2003, more than 20,000 square kilometres (7,700 sq mi) have been equipped with a subsurface drainage system and approximately 7.2 square kilometres (2.8 sq mi) of water is drained annually from areas with these systems. The total investment cost in agricultural drainage over 27 years from 1973 to 2002 was about $3.1 billion covering the cost of design, construction, maintenance, research and training. During this period 11 large-scale projects were implemented with financial support from World Bank and other donors.
Effects
The High Dam has resulted in protection from floods and droughts, an increase in agricultural production and employment, electricity production, and improved navigation that also benefits tourism. Conversely, the dam flooded a large area, causing the relocation of over 100,000 people. Many archaeological sites were submerged while others were relocated. The dam is blamed for coastline erosion, soil salinity, and health problems.
The assessment of the costs and benefits of the dam remains controversial decades after its completion. According to one estimate, the annual economic benefit of the High Dam immediately after its completion was LE 255 million, $587 million using the exchange rate in 1970 of $2.30 per LE 1): LE 140 million from agricultural production, LE 100 million from hydroelectric generation, LE 10 million from flood protection, and LE 5 million from improved navigation. At the time of its construction, total cost, including unspecified "subsidiary projects" and the extension of electric power lines, amounted to LE 450 million. Not taking into account the negative environmental and social effects of the dam, its costs are thus estimated to have been recovered within only two years. One observer notes: "The impacts of the Aswan High Dam have been overwhelmingly positive. Although the Dam has contributed to some environmental problems, these have proved to be significantly less severe than was generally expected, or currently believed by many people." Another observer disagreed and he recommended that the dam should be torn down. Tearing it down would cost only a fraction of the funds required for "continually combating the dam's consequential damage" and 500,000 hectares (1,900 sq mi) of fertile land could be reclaimed from the layers of mud on the bed of the drained reservoir. Samuel C. Florman wrote about the dam: "As a structure it is a success. But in its effect on the ecology of the Nile Basin – most of which could have been predicted – it is a failure".
Periodic floods and droughts have affected Egypt since ancient times. The dam mitigated the effects of floods, such as those in 1964, 1973, and 1988. Navigation along the river has been improved, both upstream and downstream of the dam. Sailing along the Nile is a favorite tourism activity, which is mainly done during the winter when the natural flow of the Nile would have been too low to allow navigation of cruise ships.[clarification needed] A new fishing industry has been created around Lake Nasser, though it is struggling due to its distance from any significant markets. The annual production was about 35 000 tons in the mid-1990s. Factories for the fishing industry and packaging have been set up near the Lake.
According to a 1971 CIA declassified report, Although the High Dam has not created ecological problems as serious as some observers have charged, its construction has brought economic losses as well as gains. These losses derive largely from the settling in dam's lake of the rich silt traditionally borne by the Nile. To date (1971), the main impact has been on the fishing industry. Egypt's Mediterranean catch, which once averaged 35,000-40,000 tons annually, has shrunk to 20,000 tons or less, largely because the loss of plankton nourished by the silt has eliminated the sardine population in Egyptian waters. Fishing in high dam's lake may in time at least partly offset the loss of saltwater fish, but only the most optimistic estimates place the eventual catch as high as 15,000-20,000 tons. Lack of continuing silt deposits at the mouth of the river also has contributed to a serious erosion problem. Commercial fertilizer requirements and salination and drainage difficulties, already large in perennially irrigated areas of Lower and Middle Egypt, will be somewhat increased in Upper Egypt by the change to perennial irrigation.
The dams also protected Egypt from the droughts in 1972–73 and 1983–87 that devastated East and West Africa. The High Dam allowed Egypt to reclaim about 2.0 million feddan (840,000 hectares) in the Nile Delta and along the Nile Valley, increasing the country's irrigated area by a third. The increase was brought about both by irrigating what used to be desert and by bringing under cultivation of 385,000 hectares (950,000 acres) that were previously used as flood retention basins. About half a million families were settled on these new lands. In particular the area under rice and sugar cane cultivation increased. In addition, about 1 million feddan (420,000 hectares), mostly in Upper Egypt, were converted from flood irrigation with only one crop per year to perennial irrigation allowing two or more crops per year. On other previously irrigated land, yields increased because water could be made available at critical low-flow periods. For example, wheat yields in Egypt tripled between 1952 and 1991 and better availability of water contributed to this increase. Most of the 32 km3 of freshwater, or almost 40 percent of the average flow of the Nile that were previously lost to the sea every year could be put to beneficial use. While about 10 km3 of the water saved is lost due to evaporation in Lake Nasser, the amount of water available for irrigation still increased by 22 km3. Other estimates put evaporation from Lake Nasser at between 10 and 16 cubic km per year.
Electricity production
The dam powers twelve generators each rated at 175 megawatts (235,000 hp), with a total of 2.1 gigawatts (2,800,000 hp). Power generation began in 1967. When the High Dam first reached peak output it produced around half of Egypt's production of electric power (about 15 percent by 1998), and it gave most Egyptian villages the use of electricity for the first time. The High Dam has also improved the efficiency and the extension of the Old Aswan Hydropower stations by regulating upstream flows.
All High Dam power facilities were completed ahead of schedule. 12 turbines were installed and tested, giving the plant an installed capacity of 2,100 megawatts (MW), or more than twice the national total in 1960. With this capacity, the Aswan plant can produce 10 billion kWh of energy yearly. Two 500-kilovolt trunk lines to Cairo have been completed, and initial transmission problems, stemming mainly from poor insulators, were solved. Also, the damage inflicted on a main transformer station in 1968 by Israeli commandos has been repaired, and the Aswan plant is fully integrated with the power network in Lower Egypt. By 1971 estimation, Power output at Aswan, won't reach much more than half of the plant's theoretical capacity, because of limited water supplies and the differing seasonal water-use patterns for irrigation and power production. Agricultural demand for water in the summer far exceeds the amount needed to meet the comparatively low summer demand for electric power. Heavy summer irrigation use, however, will leave insufficient water under Egyptian control to permit hydroelectric power production at full capacity in the winter. Technical studies indicate that a maximum annual output of 5 billion kWh appears to be all that can be sustained due to fluctuations in Nile flows.
Resettlement and compensations
In Sudan, 50,000 to 70,000 Sudanese Nubians were moved from the old town of Wadi Halfa and its surrounding villages. Some were moved to a newly created settlement on the shore of Lake Nasser called New Wadi Halfa, and some were resettled approximately 700 kilometres (430 mi) south to the semi-arid Butana plain near the town of Khashm el-Girba up the Atbara River. The climate there had a regular rainy season as opposed to their previous desert habitat in which virtually no rain fell. The government developed an irrigation project, called the New Halfa Agricultural Development Scheme to grow cotton, grains, sugar cane and other crops. The Nubians were resettled in twenty five planned villages that included schools, medical facilities, and other services, including piped water and some electrification.
In Egypt, the majority of the 50,000 Nubians were moved three to ten kilometers from the Nile near Edna and Kom Ombo, 45 kilometers (28 mi) downstream from Aswan in what was called "New Nubia". Housing and facilities were built for 47 village units whose relationship to each other approximated that in Old Nubia. Irrigated land was provided to grow mainly sugar cane.
In 2019–20, Egypt started to compensate the Nubians who lost their homes following the dam impoundment.
Archaeological sites
Twenty-two monuments and architectural complexes that were threatened by flooding from Lake Nasser, including the Abu Simbel temples, were preserved by moving them to the shores of the lake under the UNESCO Nubia Campaign. Also moved were Philae, Kalabsha and Amada.
These monuments were granted to countries that helped with the works:
The Debod temple to Madrid
The Temple of Dendur to the Metropolitan Museum of Art of New York
The Temple of Taffeh to the Rijksmuseum van Oudheden of Leiden
The Temple of Ellesyia to the Museo Egizio of Turin
These items were removed to the garden area of the Sudan National Museum of Khartoum:
The temple of Ramses II at Aksha
The temple of Hatshepsut at Buhen
The temple of Khnum at Kumma
The tomb of the Nubian prince Djehuti-hotep at Debeira
The temples of Dedwen and Sesostris III at Semna
The granite columns from the Faras Cathedral
A part of the paintings of the Faras Cathedral; the other part is in the National Museum of Warsaw.
The Temple of Ptah at Gerf Hussein had its free-standing section reconstructed at New Kalabsha, alongside the Temple of Kalabsha, Beit el-Wali, and the Kiosk of Qertassi.
The remaining archaeological sites, including the Buhen fort and the cemetery of Fadrus have been flooded by Lake Nasser.
Loss of sediments
Before the construction of the High Dam, the Nile deposited sediments of various particle size – consisting of fine sand, silt and clay – on fields in Upper Egypt through its annual flood, contributing to soil fertility. However, the nutrient value of the sediment has often been overestimated. 88 percent of the sediment was carried to the sea before the construction of the High Dam. The nutrient value added to the land by the sediment was only 6,000 tons of potash, 7,000 tons of phosphorus pentoxide and 17,000 tons of nitrogen. These amounts are insignificant compared to what is needed to reach the yields achieved today in Egypt's irrigation. Also, the annual spread of sediment due to the Nile floods occurred along the banks of the Nile. Areas far from the river which never received the Nile floods before are now being irrigated.
A more serious issue of trapping of sediment by the dam is that it has increased coastline erosion surrounding the Nile Delta. The coastline erodes an estimated 125–175 m (410–574 ft) per year.
Waterlogging and increase in soil salinity
Before the construction of the High Dam, groundwater levels in the Nile Valley fluctuated 8–9 m (26–30 ft) per year with the water level of the Nile. During summer when evaporation was highest, the groundwater level was too deep to allow salts dissolved in the water to be pulled to the surface through capillary action. With the disappearance of the annual flood and heavy year-round irrigation, groundwater levels remained high with little fluctuation leading to waterlogging. Soil salinity also increased because the distance between the surface and the groundwater table was small enough (1–2 m depending on soil conditions and temperature) to allow water to be pulled up by evaporation so that the relatively small concentrations of salt in the groundwater accumulated on the soil surface over the years. Since most of the farmland did not have proper subsurface drainage to lower the groundwater table, salinization gradually affected crop yields.[31] Drainage through sub-surface drains and drainage channels is essential to prevent a deterioration of crop yields from soil salinization and waterlogging. By 2003, more than 2 million hectares have been equipped with a subsurface drainage system at a cost from 1973 to 2002 of about $3.1 billion.
Health
Contrary to many predictions made prior to the Aswan High Dam construction and publications that followed, that the prevalence of schistosomiasis (bilharzia) would increase, it did not. This assumption did not take into account the extent of perennial irrigation that was already present throughout Egypt decades before the high dam closure. By the 1950s only a small proportion of Upper Egypt had not been converted from basin (low transmission) to perennial (high transmission) irrigation. Expansion of perennial irrigation systems in Egypt did not depend on the high dam. In fact, within 15 years of the high dam closure there was solid evidence that bilharzia was declining in Upper Egypt. S. haematobium has since disappeared altogether. Suggested reasons for this include improvements in irrigation practice. In the Nile Delta, schistosomiasis had been highly endemic, with prevalence in the villages 50% or higher for almost a century before. This was a consequence of the conversion of the Delta to perennial irrigation to grow long staple cotton by the British. This has changed. Large-scale treatment programmes in the 1990s using single-dose oral medication contributed greatly to reducing the prevalence and severity of S. mansoni in the Delta.
Other effects
Sediment deposited in the reservoir is lowering the water storage capacity of Lake Nasser. The reservoir storage capacity is 162 km3, including 31 km3 dead storage at the bottom of the lake below 147 m (482 ft) above sea level, 90 km3 live storage, and 41 km3 of storage for high flood waters above 175 m (574 ft) above sea level. The annual sediment load of the Nile is about 134 million tons. This means that the dead storage volume would be filled up after 300–500 years if the sediment accumulated at the same rate throughout the area of the lake. Obviously sediment accumulates much faster at the upper reaches of the lake, where sedimentation has already affected the live storage zone.
Before the construction of the High Dam, the 50,000 km (31,000 mi) of irrigation and drainage canals in Egypt had to be dredged regularly to remove sediments. After construction of the dam, aquatic weeds grew much faster in the clearer water, helped by fertilizer residues. The total length of the infested waterways was about 27,000 km (17,000 mi) in the mid-1990s. Weeds have been gradually brought under control by manual, mechanical and biological methods.
Mediterranean fishing and brackish water lake fishery declined after the dam was finished because nutrients that flowed down the Nile to the Mediterranean were trapped behind the dam. For example, the sardine catch off the Egyptian coast declined from 18,000 tons in 1962 to a mere 460 tons in 1968, but then gradually recovered to 8,590 tons in 1992. A scientific article in the mid-1990s noted that "the mismatch between low primary productivity and relatively high levels of fish production in the region still presents a puzzle to scientists."
A concern before the construction of the High Dam had been the potential drop in river-bed level downstream of the Dam as the result of erosion caused by the flow of sediment-free water. Estimates by various national and international experts put this drop at between and 2 and 10 meters (6.6 and 32.8 ft). However, the actual drop has been measured at 0.3–0.7 meters (0.98–2.30 ft), much less than expected.[30]
The red-brick construction industry, which consisted of hundreds of factories that used Nile sediment deposits along the river, has also been negatively affected. Deprived of sediment, they started using the older alluvium of otherwise arable land taking out of production up to 120 square kilometers (46 sq mi) annually, with an estimated 1,000 square kilometers (390 sq mi) destroyed by 1984 when the government prohibited, "with only modest success," further excavation. According to one source, bricks are now being made from new techniques which use a sand-clay mixture and it has been argued that the mud-based brick industry would have suffered even if the dam had not been built.
Because of the lower turbidity of the water sunlight penetrates deeper in the Nile water. Because of this and the increased presence of nutrients from fertilizers in the water, more algae grow in the Nile. This in turn increases the costs of drinking water treatment. Apparently few experts had expected that water quality in the Nile would actually decrease because of the High Dam.
Appraisal of the Project
Although it is moot whether the project constitutes the best use of the funds spent, the Aswan Dam project unquestionably is and will continue to be economically beneficial to Egypt. The project has been expensive and it took considerable time to complete, as is usually the case with large hydroelectric developments, But Egypt now has a valuable asset with a long life and low operating costs. Even so, the wisdom of concentrating one-third of domestic saving and most of available foreign aid on a slow growth project is questionable. Since 1960, GNP has grown 50%, but mainly as a result of other investment.
Egyptian authorities were well aware that equivalent gains in output could have been achieved more quickly and more cheaply by other means. A series of low dams, similar to the barrages now contemplated, was suggested by Egyptian engineers as a more economical means of achieving up to 2,000 mW of additional generating capacity, US and WorldBank agricultural experts had long recommended improved drainage, introduction of hybrid seeds, and other such low-cost alternatives to land reclamation as a means of increasing agricultural output, In other areas, most notably the once efficient cotton textile industry, investment was needed to forestall an output decline, Implementation of these and other alternatives has been postponed rather than precluded by the High Dam project.
However, the decision to concentrate Egyptian savings and energies on the Aswan project for a decade was heavily based on non-economic factors. Nasser undoubtedly believed that a project of considerable symbolic appeal was needed to mobilize the population behind the government's economic goals, He also apparently felt that the East and West would be more easily persuaded to bid against each other for a project of this scope.
The Aswan High Dam made an appreciable contribution to Egyptian GNP, however the returns were well below what the planners had anticipated. The principal limiting factors on the High Dam's contribution to Egyptian output are a shortage of land suitable for reclamation, the high cost and long time required to bring reclaimed land to full productivity, and an inadequate water supply to meet power and irrigation goals simultaneously. The last limitation arises in part from the allocation in a 1959 agreement of more water to Sudan than was originally foreseen and in part from differences in the seasonal demand pattern of agriculture and the hydroelectric plant for the water. Irrigation requires very heavy use of water during summer months, while power generation needs peak during the winter. Ecological problems created by the dam, most of which were anticipated, have not seriously harmed the economy, although a few minor industries have been damaged.
The dam is, nonetheless, a viable project. Eventually the contribution to GNP equals as much as 20% of total investment. Moreover, the dam and associated projects provided returns that at least offset the cost of operation, repayment of foreign loans and amortisation of domestic loans.

anyways, have an amazing christmas eve/christmas/anything wherever you are!
Wendell Castle REMASTERED
This exhibition presents the recent, digitally crafted works of Wendell Castle, master furniture maker, designer, sculptor, and pioneer of the American art furniture movement. In his meditation on a career that spans nearly six decades, Castle revisits the technique that he innovated in 1963—a unique method of stack wood lamination—and re-examines it through a contemporary lens. In 2011 he purchased a computer-numerical-control (CNC) milling robot, nicknamed Mr. Chips, to investigate the role that digital fabrication might play in expanding his studio practice. The results were dramatic, allowing him to create works of greater structural complexity that were ever before possible.
Stack lamination served as Castle’s primary means of production throughout the 1960s. In this process, layers of wood are glued, clamped, built up, and carved to create the final form. This technique had been used in sculpture, but Castle applied it to furniture, and his work developed a unique, organic character that has become his signature style. Most important, this process liberated him from the rectilinear forms associated with traditional wood-working joinery.
Invited to respond to a selection of historically significant works from the 1960s, Castle has created new works through his latest practice of incorporating digital technologies into the stack-lamination process. He combined 3D scanning, 3D modeling, and CNC milling with hand building, carving, rasping, and finishing. These new works are installed in dialogue with the earlier pieces that inspired them, providing a study in form, scale, volume, and visual language. The exhibition also includes Castle’s recent explorations in bronze and fiberglass.
Castle links the past with the present by blending craftsmanship with state-of-the-art digital technologies to create ever increasingly sculptural works. Yet they remain quintessentially the hand of Wendell Castles, the master.

I used this is one of my upcoming vignettes, its not posable, of course, but it makes things look a little more realistic..
One thing I'm especially proud of on my Venator is this top hangar door. Using SNOT techniques with angular brick I was able to make this 5 steps narrowing from 4 to 2 studs. Looks pretty smooth I think :)

High Dynamic Range (HDR)
High-dynamic-range imaging (HDRI) is a high dynamic range (HDR) technique used in imaging and photography to reproduce a greater dynamic range of luminosity than is possible with standard digital imaging or photographic techniques. The aim is to present a similar range of luminance to that experienced through the human visual system. The human eye, through adaptation of the iris and other methods, adjusts constantly to adapt to a broad range of luminance present in the environment. The brain continuously interprets this information so that a viewer can see in a wide range of light conditions.
HDR images can represent a greater range of luminance levels than can be achieved using more 'traditional' methods, such as many real-world scenes containing very bright, direct sunlight to extreme shade, or very faint nebulae. This is often achieved by capturing and then combining several different, narrower range, exposures of the same subject matter. Non-HDR cameras take photographs with a limited exposure range, referred to as LDR, resulting in the loss of detail in highlights or shadows.
The two primary types of HDR images are computer renderings and images resulting from merging multiple low-dynamic-range (LDR) or standard-dynamic-range (SDR) photographs. HDR images can also be acquired using special image sensors, such as an oversampled binary image sensor.
Due to the limitations of printing and display contrast, the extended luminosity range of an HDR image has to be compressed to be made visible. The method of rendering an HDR image to a standard monitor or printing device is called tone mapping. This method reduces the overall contrast of an HDR image to facilitate display on devices or printouts with lower dynamic range, and can be applied to produce images with preserved local contrast (or exaggerated for artistic effect).
In photography, dynamic range is measured in exposure value (EV) differences (known as stops). An increase of one EV, or 'one stop', represents a doubling of the amount of light. Conversely, a decrease of one EV represents a halving of the amount of light. Therefore, revealing detail in the darkest of shadows requires high exposures, while preserving detail in very bright situations requires very low exposures. Most cameras cannot provide this range of exposure values within a single exposure, due to their low dynamic range. High-dynamic-range photographs are generally achieved by capturing multiple standard-exposure images, often using exposure bracketing, and then later merging them into a single HDR image, usually within a photo manipulation program). Digital images are often encoded in a camera's raw image format, because 8-bit JPEG encoding does not offer a wide enough range of values to allow fine transitions (and regarding HDR, later introduces undesirable effects due to lossy compression).
Any camera that allows manual exposure control can make images for HDR work, although one equipped with auto exposure bracketing (AEB) is far better suited. Images from film cameras are less suitable as they often must first be digitized, so that they can later be processed using software HDR methods.
In most imaging devices, the degree of exposure to light applied to the active element (be it film or CCD) can be altered in one of two ways: by either increasing/decreasing the size of the aperture or by increasing/decreasing the time of each exposure. Exposure variation in an HDR set is only done by altering the exposure time and not the aperture size; this is because altering the aperture size also affects the depth of field and so the resultant multiple images would be quite different, preventing their final combination into a single HDR image.
An important limitation for HDR photography is that any movement between successive images will impede or prevent success in combining them afterwards. Also, as one must create several images (often three or five and sometimes more) to obtain the desired luminance range, such a full 'set' of images takes extra time. HDR photographers have developed calculation methods and techniques to partially overcome these problems, but the use of a sturdy tripod is, at least, advised.
Some cameras have an auto exposure bracketing (AEB) feature with a far greater dynamic range than others, from the 3 EV of the Canon EOS 40D, to the 18 EV of the Canon EOS-1D Mark II. As the popularity of this imaging method grows, several camera manufactures are now offering built-in HDR features. For example, the Pentax K-7 DSLR has an HDR mode that captures an HDR image and outputs (only) a tone mapped JPEG file. The Canon PowerShot G12, Canon PowerShot S95 and Canon PowerShot S100 offer similar features in a smaller format.. Nikon's approach is called 'Active D-Lighting' which applies exposure compensation and tone mapping to the image as it comes from the sensor, with the accent being on retaing a realistic effect . Some smartphones provide HDR modes, and most mobile platforms have apps that provide HDR picture taking.
Camera characteristics such as gamma curves, sensor resolution, noise, photometric calibration and color calibration affect resulting high-dynamic-range images.
Color film negatives and slides consist of multiple film layers that respond to light differently. As a consequence, transparent originals (especially positive slides) feature a very high dynamic range
Tone mapping
Tone mapping reduces the dynamic range, or contrast ratio, of an entire image while retaining localized contrast. Although it is a distinct operation, tone mapping is often applied to HDRI files by the same software package.
Several software applications are available on the PC, Mac and Linux platforms for producing HDR files and tone mapped images. Notable titles include
Adobe Photoshop
Aurora HDR
Dynamic Photo HDR
HDR Efex Pro
HDR PhotoStudio
Luminance HDR
MagicRaw
Oloneo PhotoEngine
Photomatix Pro
PTGui
Information stored in high-dynamic-range images typically corresponds to the physical values of luminance or radiance that can be observed in the real world. This is different from traditional digital images, which represent colors as they should appear on a monitor or a paper print. Therefore, HDR image formats are often called scene-referred, in contrast to traditional digital images, which are device-referred or output-referred. Furthermore, traditional images are usually encoded for the human visual system (maximizing the visual information stored in the fixed number of bits), which is usually called gamma encoding or gamma correction. The values stored for HDR images are often gamma compressed (power law) or logarithmically encoded, or floating-point linear values, since fixed-point linear encodings are increasingly inefficient over higher dynamic ranges.
HDR images often don't use fixed ranges per color channel—other than traditional images—to represent many more colors over a much wider dynamic range. For that purpose, they don't use integer values to represent the single color channels (e.g., 0-255 in an 8 bit per pixel interval for red, green and blue) but instead use a floating point representation. Common are 16-bit (half precision) or 32-bit floating point numbers to represent HDR pixels. However, when the appropriate transfer function is used, HDR pixels for some applications can be represented with a color depth that has as few as 10–12 bits for luminance and 8 bits for chrominance without introducing any visible quantization artifacts.
History of HDR photography
The idea of using several exposures to adequately reproduce a too-extreme range of luminance was pioneered as early as the 1850s by Gustave Le Gray to render seascapes showing both the sky and the sea. Such rendering was impossible at the time using standard methods, as the luminosity range was too extreme. Le Gray used one negative for the sky, and another one with a longer exposure for the sea, and combined the two into one picture in positive.
Mid 20th century
Manual tone mapping was accomplished by dodging and burning – selectively increasing or decreasing the exposure of regions of the photograph to yield better tonality reproduction. This was effective because the dynamic range of the negative is significantly higher than would be available on the finished positive paper print when that is exposed via the negative in a uniform manner. An excellent example is the photograph Schweitzer at the Lamp by W. Eugene Smith, from his 1954 photo essay A Man of Mercy on Dr. Albert Schweitzer and his humanitarian work in French Equatorial Africa. The image took 5 days to reproduce the tonal range of the scene, which ranges from a bright lamp (relative to the scene) to a dark shadow.
Ansel Adams elevated dodging and burning to an art form. Many of his famous prints were manipulated in the darkroom with these two methods. Adams wrote a comprehensive book on producing prints called The Print, which prominently features dodging and burning, in the context of his Zone System.
With the advent of color photography, tone mapping in the darkroom was no longer possible due to the specific timing needed during the developing process of color film. Photographers looked to film manufacturers to design new film stocks with improved response, or continued to shoot in black and white to use tone mapping methods.
Color film capable of directly recording high-dynamic-range images was developed by Charles Wyckoff and EG&G "in the course of a contract with the Department of the Air Force". This XR film had three emulsion layers, an upper layer having an ASA speed rating of 400, a middle layer with an intermediate rating, and a lower layer with an ASA rating of 0.004. The film was processed in a manner similar to color films, and each layer produced a different color. The dynamic range of this extended range film has been estimated as 1:108. It has been used to photograph nuclear explosions, for astronomical photography, for spectrographic research, and for medical imaging. Wyckoff's detailed pictures of nuclear explosions appeared on the cover of Life magazine in the mid-1950s.
Late 20th century
Georges Cornuéjols and licensees of his patents (Brdi, Hymatom) introduced the principle of HDR video image, in 1986, by interposing a matricial LCD screen in front of the camera's image sensor, increasing the sensors dynamic by five stops. The concept of neighborhood tone mapping was applied to video cameras by a group from the Technion in Israel led by Dr. Oliver Hilsenrath and Prof. Y.Y.Zeevi who filed for a patent on this concept in 1988.
In February and April 1990, Georges Cornuéjols introduced the first real-time HDR camera that combined two images captured by a sensor3435 or simultaneously3637 by two sensors of the camera. This process is known as bracketing used for a video stream.
In 1991, the first commercial video camera was introduced that performed real-time capturing of multiple images with different exposures, and producing an HDR video image, by Hymatom, licensee of Georges Cornuéjols.
Also in 1991, Georges Cornuéjols introduced the HDR+ image principle by non-linear accumulation of images to increase the sensitivity of the camera: for low-light environments, several successive images are accumulated, thus increasing the signal to noise ratio.
In 1993, another commercial medical camera producing an HDR video image, by the Technion.
Modern HDR imaging uses a completely different approach, based on making a high-dynamic-range luminance or light map using only global image operations (across the entire image), and then tone mapping the result. Global HDR was first introduced in 19931 resulting in a mathematical theory of differently exposed pictures of the same subject matter that was published in 1995 by Steve Mann and Rosalind Picard.
On October 28, 1998, Ben Sarao created one of the first nighttime HDR+G (High Dynamic Range + Graphic image)of STS-95 on the launch pad at NASA's Kennedy Space Center. It consisted of four film images of the shuttle at night that were digitally composited with additional digital graphic elements. The image was first exhibited at NASA Headquarters Great Hall, Washington DC in 1999 and then published in Hasselblad Forum, Issue 3 1993, Volume 35 ISSN 0282-5449.
The advent of consumer digital cameras produced a new demand for HDR imaging to improve the light response of digital camera sensors, which had a much smaller dynamic range than film. Steve Mann developed and patented the global-HDR method for producing digital images having extended dynamic range at the MIT Media Laboratory. Mann's method involved a two-step procedure: (1) generate one floating point image array by global-only image operations (operations that affect all pixels identically, without regard to their local neighborhoods); and then (2) convert this image array, using local neighborhood processing (tone-remapping, etc.), into an HDR image. The image array generated by the first step of Mann's process is called a lightspace image, lightspace picture, or radiance map. Another benefit of global-HDR imaging is that it provides access to the intermediate light or radiance map, which has been used for computer vision, and other image processing operations.
21st century
In 2005, Adobe Systems introduced several new features in Photoshop CS2 including Merge to HDR, 32 bit floating point image support, and HDR tone mapping.
On June 30, 2016, Microsoft added support for the digital compositing of HDR images to Windows 10 using the Universal Windows Platform.
HDR sensors
Modern CMOS image sensors can often capture a high dynamic range from a single exposure. The wide dynamic range of the captured image is non-linearly compressed into a smaller dynamic range electronic representation. However, with proper processing, the information from a single exposure can be used to create an HDR image.
Such HDR imaging is used in extreme dynamic range applications like welding or automotive work. Some other cameras designed for use in security applications can automatically provide two or more images for each frame, with changing exposure. For example, a sensor for 30fps video will give out 60fps with the odd frames at a short exposure time and the even frames at a longer exposure time. Some of the sensor may even combine the two images on-chip so that a wider dynamic range without in-pixel compression is directly available to the user for display or processing.

Infrared Photography
In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum (the filter thus looks black or deep red). ("Infrared filter" may refer either to this type of filter or to one that blocks infrared but passes other wavelengths.)
When these filters are used together with infrared-sensitive film or sensors, "in-camera effects" can be obtained; false-color or black-and-white images with a dreamlike or sometimes lurid appearance known as the "Wood Effect," an effect mainly caused by foliage (such as tree leaves and grass) strongly reflecting in the same way visible light is reflected from snow. There is a small contribution from chlorophyll fluorescence, but this is marginal and is not the real cause of the brightness seen in infrared photographs. The effect is named after the infrared photography pioneer Robert W. Wood, and not after the material wood, which does not strongly reflect infrared.
The other attributes of infrared photographs include very dark skies and penetration of atmospheric haze, caused by reduced Rayleigh scattering and Mie scattering, respectively, compared to visible light. The dark skies, in turn, result in less infrared light in shadows and dark reflections of those skies from water, and clouds will stand out strongly. These wavelengths also penetrate a few millimeters into skin and give a milky look to portraits, although eyes often look black.
Until the early 20th century, infrared photography was not possible because silver halide emulsions are not sensitive to longer wavelengths than that of blue light (and to a lesser extent, green light) without the addition of a dye to act as a color sensitizer. The first infrared photographs (as distinct from spectrographs) to be published appeared in the February 1910 edition of The Century Magazine and in the October 1910 edition of the Royal Photographic Society Journal to illustrate papers by Robert W. Wood, who discovered the unusual effects that now bear his name. The RPS co-ordinated events to celebrate the centenary of this event in 2010. Wood's photographs were taken on experimental film that required very long exposures; thus, most of his work focused on landscapes. A further set of infrared landscapes taken by Wood in Italy in 1911 used plates provided for him by CEK Mees at Wratten & Wainwright. Mees also took a few infrared photographs in Portugal in 1910, which are now in the Kodak archives.
Infrared-sensitive photographic plates were developed in the United States during World War I for spectroscopic analysis, and infrared sensitizing dyes were investigated for improved haze penetration in aerial photography. After 1930, new emulsions from Kodak and other manufacturers became useful to infrared astronomy.
Infrared photography became popular with photography enthusiasts in the 1930s when suitable film was introduced commercially. The Times regularly published landscape and aerial photographs taken by their staff photographers using Ilford infrared film. By 1937 33 kinds of infrared film were available from five manufacturers including Agfa, Kodak and Ilford. Infrared movie film was also available and was used to create day-for-night effects in motion pictures, a notable example being the pseudo-night aerial sequences in the James Cagney/Bette Davis movie The Bride Came COD.
False-color infrared photography became widely practiced with the introduction of Kodak Ektachrome Infrared Aero Film and Ektachrome Infrared EIR. The first version of this, known as Kodacolor Aero-Reversal-Film, was developed by Clark and others at the Kodak for camouflage detection in the 1940s. The film became more widely available in 35mm form in the 1960s but KODAK AEROCHROME III Infrared Film 1443 has been discontinued.
Infrared photography became popular with a number of 1960s recording artists, because of the unusual results; Jimi Hendrix, Donovan, Frank and a slow shutter speed without focus compensation, however wider apertures like f/2.0 can produce sharp photos only if the lens is meticulously refocused to the infrared index mark, and only if this index mark is the correct one for the filter and film in use. However, it should be noted that diffraction effects inside a camera are greater at infrared wavelengths so that stopping down the lens too far may actually reduce sharpness.
Most apochromatic ('APO') lenses do not have an Infrared index mark and do not need to be refocused for the infrared spectrum because they are already optically corrected into the near-infrared spectrum. Catadioptric lenses do not often require this adjustment because their mirror containing elements do not suffer from chromatic aberration and so the overall aberration is comparably less. Catadioptric lenses do, of course, still contain lenses, and these lenses do still have a dispersive property.
Infrared black-and-white films require special development times but development is usually achieved with standard black-and-white film developers and chemicals (like D-76). Kodak HIE film has a polyester film base that is very stable but extremely easy to scratch, therefore special care must be used in the handling of Kodak HIE throughout the development and printing/scanning process to avoid damage to the film. The Kodak HIE film was sensitive to 900 nm.
As of November 2, 2007, "KODAK is preannouncing the discontinuance" of HIE Infrared 35 mm film stating the reasons that, "Demand for these products has been declining significantly in recent years, and it is no longer practical to continue to manufacture given the low volume, the age of the product formulations and the complexity of the processes involved." At the time of this notice, HIE Infrared 135-36 was available at a street price of around $12.00 a roll at US mail order outlets.
Arguably the greatest obstacle to infrared film photography has been the increasing difficulty of obtaining infrared-sensitive film. However, despite the discontinuance of HIE, other newer infrared sensitive emulsions from EFKE, ROLLEI, and ILFORD are still available, but these formulations have differing sensitivity and specifications from the venerable KODAK HIE that has been around for at least two decades. Some of these infrared films are available in 120 and larger formats as well as 35 mm, which adds flexibility to their application. With the discontinuance of Kodak HIE, Efke's IR820 film has become the only IR film on the marketneeds update with good sensitivity beyond 750 nm, the Rollei film does extend beyond 750 nm but IR sensitivity falls off very rapidly.
Color infrared transparency films have three sensitized layers that, because of the way the dyes are coupled to these layers, reproduce infrared as red, red as green, and green as blue. All three layers are sensitive to blue so the film must be used with a yellow filter, since this will block blue light but allow the remaining colors to reach the film. The health of foliage can be determined from the relative strengths of green and infrared light reflected; this shows in color infrared as a shift from red (healthy) towards magenta (unhealthy). Early color infrared films were developed in the older E-4 process, but Kodak later manufactured a color transparency film that could be developed in standard E-6 chemistry, although more accurate results were obtained by developing using the AR-5 process. In general, color infrared does not need to be refocused to the infrared index mark on the lens.
In 2007 Kodak announced that production of the 35 mm version of their color infrared film (Ektachrome Professional Infrared/EIR) would cease as there was insufficient demand. Since 2011, all formats of color infrared film have been discontinued. Specifically, Aerochrome 1443 and SO-734.
There is no currently available digital camera that will produce the same results as Kodak color infrared film although the equivalent images can be produced by taking two exposures, one infrared and the other full-color, and combining in post-production. The color images produced by digital still cameras using infrared-pass filters are not equivalent to those produced on color infrared film. The colors result from varying amounts of infrared passing through the color filters on the photo sites, further amended by the Bayer filtering. While this makes such images unsuitable for the kind of applications for which the film was used, such as remote sensing of plant health, the resulting color tonality has proved popular artistically.
Color digital infrared, as part of full spectrum photography is gaining popularity. The ease of creating a softly colored photo with infrared characteristics has found interest among hobbyists and professionals.
In 2008, Los Angeles photographer, Dean Bennici started cutting and hand rolling Aerochrome color Infrared film. All Aerochrome medium and large format which exists today came directly from his lab. The trend in infrared photography continues to gain momentum with the success of photographer Richard Mosse and multiple users all around the world.
Digital camera sensors are inherently sensitive to infrared light, which would interfere with the normal photography by confusing the autofocus calculations or softening the image (because infrared light is focused differently from visible light), or oversaturating the red channel. Also, some clothing is transparent in the infrared, leading to unintended (at least to the manufacturer) uses of video cameras. Thus, to improve image quality and protect privacy, many digital cameras employ infrared blockers. Depending on the subject matter, infrared photography may not be practical with these cameras because the exposure times become overly long, often in the range of 30 seconds, creating noise and motion blur in the final image. However, for some subject matter the long exposure does not matter or the motion blur effects actually add to the image. Some lenses will also show a 'hot spot' in the centre of the image as their coatings are optimised for visible light and not for IR.
An alternative method of DSLR infrared photography is to remove the infrared blocker in front of the sensor and replace it with a filter that removes visible light. This filter is behind the mirror, so the camera can be used normally - handheld, normal shutter speeds, normal composition through the viewfinder, and focus, all work like a normal camera. Metering works but is not always accurate because of the difference between visible and infrared refraction. When the IR blocker is removed, many lenses which did display a hotspot cease to do so, and become perfectly usable for infrared photography. Additionally, because the red, green and blue micro-filters remain and have transmissions not only in their respective color but also in the infrared, enhanced infrared color may be recorded.
Since the Bayer filters in most digital cameras absorb a significant fraction of the infrared light, these cameras are sometimes not very sensitive as infrared cameras and can sometimes produce false colors in the images. An alternative approach is to use a Foveon X3 sensor, which does not have absorptive filters on it; the Sigma SD10 DSLR has a removable IR blocking filter and dust protector, which can be simply omitted or replaced by a deep red or complete visible light blocking filter. The Sigma SD14 has an IR/UV blocking filter that can be removed/installed without tools. The result is a very sensitive digital IR camera.
While it is common to use a filter that blocks almost all visible light, the wavelength sensitivity of a digital camera without internal infrared blocking is such that a variety of artistic results can be obtained with more conventional filtration. For example, a very dark neutral density filter can be used (such as the Hoya ND400) which passes a very small amount of visible light compared to the near-infrared it allows through. Wider filtration permits an SLR viewfinder to be used and also passes more varied color information to the sensor without necessarily reducing the Wood effect. Wider filtration is however likely to reduce other infrared artefacts such as haze penetration and darkened skies. This technique mirrors the methods used by infrared film photographers where black-and-white infrared film was often used with a deep red filter rather than a visually opaque one.
Another common technique with near-infrared filters is to swap blue and red channels in software (e.g. photoshop) which retains much of the characteristic 'white foliage' while rendering skies a glorious blue.
Several Sony cameras had the so-called Night Shot facility, which physically moves the blocking filter away from the light path, which makes the cameras very sensitive to infrared light. Soon after its development, this facility was 'restricted' by Sony to make it difficult for people to take photos that saw through clothing. To do this the iris is opened fully and exposure duration is limited to long times of more than 1/30 second or so. It is possible to shoot infrared but neutral density filters must be used to reduce the camera's sensitivity and the long exposure times mean that care must be taken to avoid camera-shake artifacts.
Fuji have produced digital cameras for use in forensic criminology and medicine which have no infrared blocking filter. The first camera, designated the S3 PRO UVIR, also had extended ultraviolet sensitivity (digital sensors are usually less sensitive to UV than to IR). Optimum UV sensitivity requires special lenses, but ordinary lenses usually work well for IR. In 2007, FujiFilm introduced a new version of this camera, based on the Nikon D200/ FujiFilm S5 called the IS Pro, also able to take Nikon lenses. Fuji had earlier introduced a non-SLR infrared camera, the IS-1, a modified version of the FujiFilm FinePix S9100. Unlike the S3 PRO UVIR, the IS-1 does not offer UV sensitivity. FujiFilm restricts the sale of these cameras to professional users with their EULA specifically prohibiting "unethical photographic conduct".
Phase One digital camera backs can be ordered in an infrared modified form.
Remote sensing and thermographic cameras are sensitive to longer wavelengths of infrared (see Infrared spectrum#Commonly used sub-division scheme). They may be multispectral and use a variety of technologies which may not resemble common camera or filter designs. Cameras sensitive to longer infrared wavelengths including those used in infrared astronomy often require cooling to reduce thermally induced dark currents in the sensor (see Dark current (physics)). Lower cost uncooled thermographic digital cameras operate in the Long Wave infrared band (see Thermographic camera#Uncooled infrared detectors). These cameras are generally used for building inspection or preventative maintenance but can be used for artistic pursuits as well.
Trichrome photography involves taking three exposures of the same subject on black and white film. Each exposure is taken through a red, green or blue filter.
One of the early users of the process, over a hundred years ago, was Sergey Prokudin-Gorsky , he used projectors with coloured filters to make a combined image, nowadays it can be done with photo editing software such as Photoshop.
For this trichrome, I used the Harris Shutter technique, which was invented by Robert Harris of Kodak for making colour photographs with the different primary colour layers exposed in separate time intervals in succession. Using an Olympus ECR35 35mm camera, I took three photos of the scene on black and white film (Rollei RPX400) with a red, green or blue filter in front of the lens. It took several seconds to change the filter, so moving subjects, such as clouds or people, appear in different positions and in different colours, while static subjects appear normal.
Inspired by a peterlmorris building technique. (seen here www.flickr.com/photos/rival_m/2733384962/ )
When I realized that the other technique did not support placing a cap on both sides of the wheel, I had to find a solution. This candy sucker demo shows you how to create a self-contained version while adding an alternative no-twist* method to the existing one.
The gray half pin studs connect to the bottom of the discs, and then a piece of 3 long 3mm tube is slid through the pins and used to provide additional fastening support. The gray pins enter only half way into the technic pin hole on the wheel.
It is simply not possible to seal the gaps with a 4x length axle connecting the two cylinders together, and 3x length axle is too short to connect and too long to reside inside the wheel with other elements in order to create a connection, as far as I am aware. (1x1 cones with a 2x axle MIGHT solve this, but I haven't tried it)
*This solution has enough friction to prevent loose or unwanted twisting to a point: It does not jiggle and has more initial friction compared to the technic wheel 3/4 pin technique.
It is possible to add a pair of 1/2 thick 3L liftarms and two 2L axles, which increases slightly the friction, but without axles there's no true no-twist locking.
Black friction pins are used with the tan connectors to build the stick, and the white half pin is a decorative flourish to cap off the other side of the wheel.

Introduction
In the spring of this year, representatives of the United States’ Leadership in Energy and Environmental Design (LEED), the U.K.’s Building Research Establishment Environmental Assessment Method (BRE-EAM), and the Australian Green Star rating systems initiated meetings to align their assessment tools and develop common metrics to measure CO2 equivalents from building construction. Later this summer, BRE and the French Centre Scientifique et Technique du Bâtiment (CSTB) declared their joint effort to create a Pan-European assessment method. These events represent both the global adoption of the sustainable construction philosophy and the need for developing consensus among standards.
The ideological commitment to producing sustainable buildings is an ethical response to both global and local environmental issues. However, the criteria for “green” building evaluation among international organizations continue to evolve. To some degree, the bias for operational efficiencies of new construction over the value of existing buildings has lessened in recent years. But the importance of economic and environmental metrics to construction planning and design is only likely to increase. Given the heightened political interest in global conditions, the metrics for sustainable construction have been widely adopted by national and municipal building regulators. This suggests an amended method for the evaluation of architectural resources for conservation.
Ultimately advocates for building conservation must become active participants in a potentially unfamiliar analytical dialog. Scientific and engineering methods and data must, to a certain extent, be adopted by the historic preservation professional. The “conventional” wisdom of conservation practice - namely that stewardship of our historic building stock is an act of sustainability – is increasingly subject to demonstration and verification.
In the wake of this paradigm shift, it is appropriate to consider the net effect of sustainable construction standards in practice. To date, the “green” building movement has mostly represented an incremental change rather than a radical rethinking of the built environment (Kibert, 2004). High-performance designs must also be recognized as experiments in the trial and error process to achieve “sustainable” buildings. The development of a new generation of construction materials and systems - engineered according to standards for low environmental impacts - appears remarkably similar to the post-WWII era when architecture readily embraced experimental products with limited life-cycle testing.
The existence of experimental building technologies in modern movement buildings has long been identified as a conflict to preservation’s paradigm to conserve original building fabric. This debate, however, rarely addresses the design movement’s underlying focus on “performance” – an essentially non-existent concept in pre-19th century architecture. The era’s mantra of “doing more with less” resulted in more than just a compression of construction assemblies- it introduced the operational logic of industry, specifically the machine, to the art of architecture. One could argue that the very presence of rapidly-deteriorating, petroleum-based products within 20th-century buildings suggests the need for a conceptual understanding of conservation more akin to automobiles than to pre-modern architecture.
In recognition of the modern movement’s nascent adoption of new material technology, and yet its significant reliance on durable construction methods, this essay considers the opportunities and constraints of various models for the assessment of sustainable building.
Birth of the Green
The “green” building movement reflects many societal factors, not least of which are the escalation in fuel prices and the growing popular concern for global warming. The present condition represents an epic paradox of civilization: although “cheap” energy supported exponential worldwide growth and modernization, the resulting competition and demand cannot be sustained by the original fuel source. Of course this observation is not new, but we among oil-consuming economies “fell off the wagon” sometime in the last three decades.
At the time of the last energy crises, the concerns for nature first written by Henry David Thoreau had matured into an environmental movement within western nations. In the developing century of thought, the human role of “stewardship” found recognition and asserted that mankind’s fate is linked to that of nature; concluding there can be no competition between the two. Therefore, civilization must mitigate the long-term impact of its reliance on natural resources. The definition of “mitigation” prompted a debate of natural vs. cultural priorities. An early example was the argument of land management versus preservation, lead by Gifford Pinchot and John Muir. Overall, the parallel movements have been unified by many seminal texts and thinkers, but an ideological tug-of-war has occasionally pitted one priority against the other. Today, some of this polarity has been diminished through the recent concept of the “triple bottom line”. This more inclusive, and arguably sustainable action model, suggests equal footing for economic, environmental, and social criteria.
Building Impacts
Proponents of high-performance construction often quote an estimate that during a building’s lifespan, the majority of its energy expenditure is consumed by building operations. Although this estimate does not hold true for the full history of extant buildings, conservators generally agree that this pattern of consumption typifies construction of the 19th-20th centuries. The lifespan ratio is commonly differentiated as 16% initial embodied energy, 10% recurring embodied energy, and 74% building operations.
Initial embodied energy in buildings represents the non-renewable energy consumed in the acquisition of raw materials, their processing, manufacturing, transportation to site, and construction. The recurring embodied energy in buildings represents the non-renewable energy consumed to maintain, repair, restore, refurbish or replace materials, components or systems during the life of the building.
Building upon the early research of architect Richard Stein and others, the U.S. Advisory Council on Historic Preservation (ACHP) commissioned a landmark study (Booz, Allen, Hamilton 1979) based on an extensive analysis of U.S. building industry data. Although the data for industrial processes has not been updated since its initial compilation, the original calculations represent the prolific period of post-WWII construction.
In most circumstances, initial embodied energy is significantly less than the energy consumed by a building over its lifetime. Green building research has therefore focused primarily on improving efficiencies in building operations and reducing construction waste and pollution.
Comparison of Standards
To date, the LEED program has certified over one thousand buildings, with thousands more waiting in application. The majority of these certifications have been voluntary. Following the early adoption by the U.S. General Services Administration (GSA), municipalities, and some universities, LEED certification has been mandated by many facility owners and operators. Since the incorporation of the LEED standards, alternative rating systems have been developed and warrant consideration in context.
The U.K.’s BREEAM rating system was introduced in 1990 and has been recognized as the first environmental building assessment tool. Following the U.N.’s “Earth Summit” in Rio de Janeiro, the international momentum for such standards grew. The non-profit U.S. Green Building Council was established in 1993 and introduced LEED in 2000. In the same year, the Canadian Building Owners and Mangers Association (BOMA) released the Green Globes rating system. It must be noted that both systems were heavily influenced by BREEAM, and in fact Green Globes grew out of a 1996 BREEAM franchise by the Canadian Standards Association. Unique to the BOMA revision, however, was their partnership with the joint U.S.-Canadian non-profit Athena Institute. Beginning in the 1990s, the institute was devoted to the research and development of material life-cycle assessment tools for new and existing building construction.
Today, BREEAM, LEED, and Green Globes are the most widely used of more than ten independently-authored “green” building programs developed internationally over the past 20 years. The top three have expanded their systems to other countries; Green Globes entered the U.S. market through the non-profit Green Building Initiative (GBI) in 2005 and is finalizing ANSI certification; LEED has been franchised for use by non-profit Green Building Councils in India, Brazil, and Canada.
By 2006, the emerging market competition for “green” standards became apparent when the GBI filed a grievance against the GSA for their endorsement and requirement of LEED certification. In response, the GSA signed a Memorandum of Understanding to operate “rating system neutral,” maintaining however that LEED is currently the “most credible rating system available to meet GSA’s needs” and will re-evaluate systems every five years.
It is difficult to forecast what the afore-mentioned rating system partnerships will yield. Although multiple standards allows for the intrinsic variability of the construction market (private/public, residential/ commercial/institutional), the use of variable metrics problematizes the comparison of impacts which are decidedly global in their nature.
Given the common roots and similar goals, the LEED and Green Globes standards are more similar than different. A 2006 comparison by the University of Minnesota identified eight generic categories common to both analyses: 1) Energy Use; 2) Water Use; 3) Pollution; 4) Material/Product Inputs; 5) Indoor Air Quality & Occupant Comfort; 6) Transport; 7) Site Ecology; and 8) Other Sustainable Design. On the surface, the Green Globes system was initially credited with providing a less expensive and more efficient means of building certification through an on-line mechanism. In some cases, however, the “yes/no” format of the web-based data system was criticized as being prone to interpretation. LEED recently-introduced version 3 has notably replaced their paper-based system with a web-based format. However in their substance, the two systems offer differing values for the conservation of existing buildings.
Promise of LCA
Life cycle assessment (LCA) attempts to quantify the environmental impacts of a product or service caused or necessitated by its existence. The assessment method provides a systematic view of the environmental aspects of a product from “cradle to grave.” This includes: 1) a description of the entire product’s life-cycle; 2) key environmental impacts from production and use of the product; 3) the product’s functional quality. Based on these three conditions, the LCA quantifies a product’s range of environmental impacts (Trusty, 2004).
In the concept of embodied energy, it was earlier noted that the energy required to operate a building over its life exceeds the energy attributed to the products used in its construction. This statement does not take into account other embodied effects such as toxic releases to water, effects during the resource extraction and manufacturing stages that greatly outweigh any releases associated with building operations. Byproducts from the manufacture of long lifespan materials, such as iron, steel, hydraulic cements, and lime, have a significant impact on global warming. As well, the extraction of iron, sand, and gravel also contribute to natural resource depletion.
Research conducted by the Athena Institute demonstrates the value of retaining structural and envelope systems, which on average account for half of a building’s embodied energy (Cole and Kernan, 1996). This ability for detailed itemized assessment is well suited to the modern movement’s development of core and shell construction technology.
For example, two scenarios of “Impact Avoidance” can be used to estimate the environmental effects that are avoided by rehabilitating a building. The minimum avoided environmental impact case involves saving only the structural system of an existing building, with the rest demolished and replaced. The avoided impacts equal the effects of 1) demolishing a structural system and 2) rebuilding a comparable structural system. This scenario is demonstrated by the curtain wall replacement project for the Lever House and in development for the United Nations secretariat tower. In both cases, the effects of demolishing the envelope are not avoided. The maximum scenario involves saving the envelope as well as the structure, with avoided impacts equal to the effects of: 1) demolishing a structural/envelope system and 2) rebuilding a comparable structural/envelope system. The rehabilitation of the Van Nelle Factory in Rotterdam remains one of the most comprehensive examples of this alternative to date.
Until recently, both the LEED and Green Globes rating systems were criticized for not rationally weighting their assessment criteria according to environmental relevance. Although some LCA inconsistencies remain, Green Globes has been credited with including explicit rating criteria for both life-cycle strategies and building durability/ adaptability. LEED, however, historically has favored specific products according to LCA impact. LEED version 3 has re-distributed the credit values of its criteria according to LCA, but there is no single criterion that explicitly evaluates the cumulative life-cycle of a construction project. For example, the “Materials and Re-use” section requires the use of rapidly renewable materials to reduce the use of long-cycle renewable materials. However, there is no allowance for evaluating the impact of using a rapidly renewable material that must be replaced 10 times more frequently than its long-cycle alternative. Notably, a consortium of university facility managers has recently decided to eliminate the installation of bamboo flooring from future projects due to its limited service life in their prior LEED projects.
Conclusion
“In exploring the primary general categories of 'green' or 'sustainable' design and construction (energy, durability, air quality, and environmental impacts) and the ability to develop and specify requirements and standards of performance, measurement is a critical issue. Specifically, if you can't measure it, it is difficult to set up specific requirements and standards for it.” (Smith et al., 2006)
The professional evolution of preservation has lead to scientific methods and technologies to physically support the conservation of historic structures and sites. In turn, measurements have been conducted to demonstrate the positive economic impact of this mission. Despite some occasional reluctance, metrics have become fundamental to practice.
In deference to the legitimacy of environmental concerns, one cannot address today's global condition using yesterday's individualized arguments. This has occasionally been a shortcoming of the policy statements of historic preservation leadership. In the wake of the last energy crises, the aforementioned ACHP’s substantial investment in embodied energy research was an appropriate response. However, during that same period, the Secretary of the Interior Standards for Rehabilitation was revised for only a narrow consideration of energy efficiency. Although the topic was addressed (primarily the weatherizing of wood sash windows), it was not sufficiently encouraged, nor have the challenges of integrating both criteria been explored.
During the past boom of U.S. construction, the values of conservation and building integration largely lost out to the practice of tabula rasa- which the private development community has historically preferred for project expediency. Preservation advocates can attest to the large number of buildings demolished before the end of their technical service life due to a common list of “red herrings” that may now include operational inefficiency. It is too simplistic to conclude that modern architecture is logically produced and removed from the landscape based on its original bias for experimentation and technological innovation. To offer a counterpoint, there is a fundamental difference between “shortening the replacement cycle” of our mechanical systems versus our building stock and by extension communities and architectural heritage.
Architectural preservation has repeatedly been argued to be an act of sustainability. In the immediate future, LCA methodology suggests a potential bridge between the preservation community’s interest in increasingly rare building materials and techniques, with the environmental principles supporting “green” building standards. But as a caution against any suggestion of a “silver bullet”, LCA expert Arnold Tukker offers the following: “It will never be possible to solve controversial discussions about products with an LCIA [life cycle inventory assessment] method that is based solely on mathematical relations between interventions and protection areas. There are simply too many uncertainties, there is too much ignorance, and they can only be overcome by all kinds of subjective, subtle, and basically value-laden choices. …”
Preservation and conservation advocates are tasked with addressing the present paradigm shift. Future programs and processes within both academia and the profession must acknowledge the environmental impacts of construction. Simultaneously, those forces must impart the values of social interaction and cultural enrichment inherent to architectural heritage to expand the popular definition of sustainability.

10 Sept 2008 IR HDR Images.
High Dynamic Range (HDR)
High-dynamic-range imaging (HDRI) is a high dynamic range (HDR) technique used in imaging and photography to reproduce a greater dynamic range of luminosity than is possible with standard digital imaging or photographic techniques. The aim is to present a similar range of luminance to that experienced through the human visual system. The human eye, through adaptation of the iris and other methods, adjusts constantly to adapt to a broad range of luminance present in the environment. The brain continuously interprets this information so that a viewer can see in a wide range of light conditions.
HDR images can represent a greater range of luminance levels than can be achieved using more 'traditional' methods, such as many real-world scenes containing very bright, direct sunlight to extreme shade, or very faint nebulae. This is often achieved by capturing and then combining several different, narrower range, exposures of the same subject matter. Non-HDR cameras take photographs with a limited exposure range, referred to as LDR, resulting in the loss of detail in highlights or shadows.
The two primary types of HDR images are computer renderings and images resulting from merging multiple low-dynamic-range (LDR) or standard-dynamic-range (SDR) photographs. HDR images can also be acquired using special image sensors, such as an oversampled binary image sensor.
Due to the limitations of printing and display contrast, the extended luminosity range of an HDR image has to be compressed to be made visible. The method of rendering an HDR image to a standard monitor or printing device is called tone mapping. This method reduces the overall contrast of an HDR image to facilitate display on devices or printouts with lower dynamic range, and can be applied to produce images with preserved local contrast (or exaggerated for artistic effect).
In photography, dynamic range is measured in exposure value (EV) differences (known as stops). An increase of one EV, or 'one stop', represents a doubling of the amount of light. Conversely, a decrease of one EV represents a halving of the amount of light. Therefore, revealing detail in the darkest of shadows requires high exposures, while preserving detail in very bright situations requires very low exposures. Most cameras cannot provide this range of exposure values within a single exposure, due to their low dynamic range. High-dynamic-range photographs are generally achieved by capturing multiple standard-exposure images, often using exposure bracketing, and then later merging them into a single HDR image, usually within a photo manipulation program). Digital images are often encoded in a camera's raw image format, because 8-bit JPEG encoding does not offer a wide enough range of values to allow fine transitions (and regarding HDR, later introduces undesirable effects due to lossy compression).
Any camera that allows manual exposure control can make images for HDR work, although one equipped with auto exposure bracketing (AEB) is far better suited. Images from film cameras are less suitable as they often must first be digitized, so that they can later be processed using software HDR methods.
In most imaging devices, the degree of exposure to light applied to the active element (be it film or CCD) can be altered in one of two ways: by either increasing/decreasing the size of the aperture or by increasing/decreasing the time of each exposure. Exposure variation in an HDR set is only done by altering the exposure time and not the aperture size; this is because altering the aperture size also affects the depth of field and so the resultant multiple images would be quite different, preventing their final combination into a single HDR image.
An important limitation for HDR photography is that any movement between successive images will impede or prevent success in combining them afterwards. Also, as one must create several images (often three or five and sometimes more) to obtain the desired luminance range, such a full 'set' of images takes extra time. HDR photographers have developed calculation methods and techniques to partially overcome these problems, but the use of a sturdy tripod is, at least, advised.
Some cameras have an auto exposure bracketing (AEB) feature with a far greater dynamic range than others, from the 3 EV of the Canon EOS 40D, to the 18 EV of the Canon EOS-1D Mark II. As the popularity of this imaging method grows, several camera manufactures are now offering built-in HDR features. For example, the Pentax K-7 DSLR has an HDR mode that captures an HDR image and outputs (only) a tone mapped JPEG file. The Canon PowerShot G12, Canon PowerShot S95 and Canon PowerShot S100 offer similar features in a smaller format.. Nikon's approach is called 'Active D-Lighting' which applies exposure compensation and tone mapping to the image as it comes from the sensor, with the accent being on retaing a realistic effect . Some smartphones provide HDR modes, and most mobile platforms have apps that provide HDR picture taking.
Camera characteristics such as gamma curves, sensor resolution, noise, photometric calibration and color calibration affect resulting high-dynamic-range images.
Color film negatives and slides consist of multiple film layers that respond to light differently. As a consequence, transparent originals (especially positive slides) feature a very high dynamic range
Tone mapping
Tone mapping reduces the dynamic range, or contrast ratio, of an entire image while retaining localized contrast. Although it is a distinct operation, tone mapping is often applied to HDRI files by the same software package.
Several software applications are available on the PC, Mac and Linux platforms for producing HDR files and tone mapped images. Notable titles include
Adobe Photoshop
Aurora HDR
Dynamic Photo HDR
HDR Efex Pro
HDR PhotoStudio
Luminance HDR
MagicRaw
Oloneo PhotoEngine
Photomatix Pro
PTGui
Information stored in high-dynamic-range images typically corresponds to the physical values of luminance or radiance that can be observed in the real world. This is different from traditional digital images, which represent colors as they should appear on a monitor or a paper print. Therefore, HDR image formats are often called scene-referred, in contrast to traditional digital images, which are device-referred or output-referred. Furthermore, traditional images are usually encoded for the human visual system (maximizing the visual information stored in the fixed number of bits), which is usually called gamma encoding or gamma correction. The values stored for HDR images are often gamma compressed (power law) or logarithmically encoded, or floating-point linear values, since fixed-point linear encodings are increasingly inefficient over higher dynamic ranges.
HDR images often don't use fixed ranges per color channel—other than traditional images—to represent many more colors over a much wider dynamic range. For that purpose, they don't use integer values to represent the single color channels (e.g., 0-255 in an 8 bit per pixel interval for red, green and blue) but instead use a floating point representation. Common are 16-bit (half precision) or 32-bit floating point numbers to represent HDR pixels. However, when the appropriate transfer function is used, HDR pixels for some applications can be represented with a color depth that has as few as 10–12 bits for luminance and 8 bits for chrominance without introducing any visible quantization artifacts.
History of HDR photography
The idea of using several exposures to adequately reproduce a too-extreme range of luminance was pioneered as early as the 1850s by Gustave Le Gray to render seascapes showing both the sky and the sea. Such rendering was impossible at the time using standard methods, as the luminosity range was too extreme. Le Gray used one negative for the sky, and another one with a longer exposure for the sea, and combined the two into one picture in positive.
Mid 20th century
Manual tone mapping was accomplished by dodging and burning – selectively increasing or decreasing the exposure of regions of the photograph to yield better tonality reproduction. This was effective because the dynamic range of the negative is significantly higher than would be available on the finished positive paper print when that is exposed via the negative in a uniform manner. An excellent example is the photograph Schweitzer at the Lamp by W. Eugene Smith, from his 1954 photo essay A Man of Mercy on Dr. Albert Schweitzer and his humanitarian work in French Equatorial Africa. The image took 5 days to reproduce the tonal range of the scene, which ranges from a bright lamp (relative to the scene) to a dark shadow.
Ansel Adams elevated dodging and burning to an art form. Many of his famous prints were manipulated in the darkroom with these two methods. Adams wrote a comprehensive book on producing prints called The Print, which prominently features dodging and burning, in the context of his Zone System.
With the advent of color photography, tone mapping in the darkroom was no longer possible due to the specific timing needed during the developing process of color film. Photographers looked to film manufacturers to design new film stocks with improved response, or continued to shoot in black and white to use tone mapping methods.
Color film capable of directly recording high-dynamic-range images was developed by Charles Wyckoff and EG&G "in the course of a contract with the Department of the Air Force". This XR film had three emulsion layers, an upper layer having an ASA speed rating of 400, a middle layer with an intermediate rating, and a lower layer with an ASA rating of 0.004. The film was processed in a manner similar to color films, and each layer produced a different color. The dynamic range of this extended range film has been estimated as 1:108. It has been used to photograph nuclear explosions, for astronomical photography, for spectrographic research, and for medical imaging. Wyckoff's detailed pictures of nuclear explosions appeared on the cover of Life magazine in the mid-1950s.
Late 20th century
Georges Cornuéjols and licensees of his patents (Brdi, Hymatom) introduced the principle of HDR video image, in 1986, by interposing a matricial LCD screen in front of the camera's image sensor, increasing the sensors dynamic by five stops. The concept of neighborhood tone mapping was applied to video cameras by a group from the Technion in Israel led by Dr. Oliver Hilsenrath and Prof. Y.Y.Zeevi who filed for a patent on this concept in 1988.
In February and April 1990, Georges Cornuéjols introduced the first real-time HDR camera that combined two images captured by a sensor3435 or simultaneously3637 by two sensors of the camera. This process is known as bracketing used for a video stream.
In 1991, the first commercial video camera was introduced that performed real-time capturing of multiple images with different exposures, and producing an HDR video image, by Hymatom, licensee of Georges Cornuéjols.
Also in 1991, Georges Cornuéjols introduced the HDR+ image principle by non-linear accumulation of images to increase the sensitivity of the camera: for low-light environments, several successive images are accumulated, thus increasing the signal to noise ratio.
In 1993, another commercial medical camera producing an HDR video image, by the Technion.
Modern HDR imaging uses a completely different approach, based on making a high-dynamic-range luminance or light map using only global image operations (across the entire image), and then tone mapping the result. Global HDR was first introduced in 19931 resulting in a mathematical theory of differently exposed pictures of the same subject matter that was published in 1995 by Steve Mann and Rosalind Picard.
On October 28, 1998, Ben Sarao created one of the first nighttime HDR+G (High Dynamic Range + Graphic image)of STS-95 on the launch pad at NASA's Kennedy Space Center. It consisted of four film images of the shuttle at night that were digitally composited with additional digital graphic elements. The image was first exhibited at NASA Headquarters Great Hall, Washington DC in 1999 and then published in Hasselblad Forum, Issue 3 1993, Volume 35 ISSN 0282-5449.
The advent of consumer digital cameras produced a new demand for HDR imaging to improve the light response of digital camera sensors, which had a much smaller dynamic range than film. Steve Mann developed and patented the global-HDR method for producing digital images having extended dynamic range at the MIT Media Laboratory. Mann's method involved a two-step procedure: (1) generate one floating point image array by global-only image operations (operations that affect all pixels identically, without regard to their local neighborhoods); and then (2) convert this image array, using local neighborhood processing (tone-remapping, etc.), into an HDR image. The image array generated by the first step of Mann's process is called a lightspace image, lightspace picture, or radiance map. Another benefit of global-HDR imaging is that it provides access to the intermediate light or radiance map, which has been used for computer vision, and other image processing operations.
21st century
In 2005, Adobe Systems introduced several new features in Photoshop CS2 including Merge to HDR, 32 bit floating point image support, and HDR tone mapping.
On June 30, 2016, Microsoft added support for the digital compositing of HDR images to Windows 10 using the Universal Windows Platform.
HDR sensors
Modern CMOS image sensors can often capture a high dynamic range from a single exposure. The wide dynamic range of the captured image is non-linearly compressed into a smaller dynamic range electronic representation. However, with proper processing, the information from a single exposure can be used to create an HDR image.
Such HDR imaging is used in extreme dynamic range applications like welding or automotive work. Some other cameras designed for use in security applications can automatically provide two or more images for each frame, with changing exposure. For example, a sensor for 30fps video will give out 60fps with the odd frames at a short exposure time and the even frames at a longer exposure time. Some of the sensor may even combine the two images on-chip so that a wider dynamic range without in-pixel compression is directly available to the user for display or processing.

Infrared Photography
In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum (the filter thus looks black or deep red). ("Infrared filter" may refer either to this type of filter or to one that blocks infrared but passes other wavelengths.)
When these filters are used together with infrared-sensitive film or sensors, "in-camera effects" can be obtained; false-color or black-and-white images with a dreamlike or sometimes lurid appearance known as the "Wood Effect," an effect mainly caused by foliage (such as tree leaves and grass) strongly reflecting in the same way visible light is reflected from snow. There is a small contribution from chlorophyll fluorescence, but this is marginal and is not the real cause of the brightness seen in infrared photographs. The effect is named after the infrared photography pioneer Robert W. Wood, and not after the material wood, which does not strongly reflect infrared.
The other attributes of infrared photographs include very dark skies and penetration of atmospheric haze, caused by reduced Rayleigh scattering and Mie scattering, respectively, compared to visible light. The dark skies, in turn, result in less infrared light in shadows and dark reflections of those skies from water, and clouds will stand out strongly. These wavelengths also penetrate a few millimeters into skin and give a milky look to portraits, although eyes often look black.
Until the early 20th century, infrared photography was not possible because silver halide emulsions are not sensitive to longer wavelengths than that of blue light (and to a lesser extent, green light) without the addition of a dye to act as a color sensitizer. The first infrared photographs (as distinct from spectrographs) to be published appeared in the February 1910 edition of The Century Magazine and in the October 1910 edition of the Royal Photographic Society Journal to illustrate papers by Robert W. Wood, who discovered the unusual effects that now bear his name. The RPS co-ordinated events to celebrate the centenary of this event in 2010. Wood's photographs were taken on experimental film that required very long exposures; thus, most of his work focused on landscapes. A further set of infrared landscapes taken by Wood in Italy in 1911 used plates provided for him by CEK Mees at Wratten & Wainwright. Mees also took a few infrared photographs in Portugal in 1910, which are now in the Kodak archives.
Infrared-sensitive photographic plates were developed in the United States during World War I for spectroscopic analysis, and infrared sensitizing dyes were investigated for improved haze penetration in aerial photography. After 1930, new emulsions from Kodak and other manufacturers became useful to infrared astronomy.
Infrared photography became popular with photography enthusiasts in the 1930s when suitable film was introduced commercially. The Times regularly published landscape and aerial photographs taken by their staff photographers using Ilford infrared film. By 1937 33 kinds of infrared film were available from five manufacturers including Agfa, Kodak and Ilford. Infrared movie film was also available and was used to create day-for-night effects in motion pictures, a notable example being the pseudo-night aerial sequences in the James Cagney/Bette Davis movie The Bride Came COD.
False-color infrared photography became widely practiced with the introduction of Kodak Ektachrome Infrared Aero Film and Ektachrome Infrared EIR. The first version of this, known as Kodacolor Aero-Reversal-Film, was developed by Clark and others at the Kodak for camouflage detection in the 1940s. The film became more widely available in 35mm form in the 1960s but KODAK AEROCHROME III Infrared Film 1443 has been discontinued.
Infrared photography became popular with a number of 1960s recording artists, because of the unusual results; Jimi Hendrix, Donovan, Frank and a slow shutter speed without focus compensation, however wider apertures like f/2.0 can produce sharp photos only if the lens is meticulously refocused to the infrared index mark, and only if this index mark is the correct one for the filter and film in use. However, it should be noted that diffraction effects inside a camera are greater at infrared wavelengths so that stopping down the lens too far may actually reduce sharpness.
Most apochromatic ('APO') lenses do not have an Infrared index mark and do not need to be refocused for the infrared spectrum because they are already optically corrected into the near-infrared spectrum. Catadioptric lenses do not often require this adjustment because their mirror containing elements do not suffer from chromatic aberration and so the overall aberration is comparably less. Catadioptric lenses do, of course, still contain lenses, and these lenses do still have a dispersive property.
Infrared black-and-white films require special development times but development is usually achieved with standard black-and-white film developers and chemicals (like D-76). Kodak HIE film has a polyester film base that is very stable but extremely easy to scratch, therefore special care must be used in the handling of Kodak HIE throughout the development and printing/scanning process to avoid damage to the film. The Kodak HIE film was sensitive to 900 nm.
As of November 2, 2007, "KODAK is preannouncing the discontinuance" of HIE Infrared 35 mm film stating the reasons that, "Demand for these products has been declining significantly in recent years, and it is no longer practical to continue to manufacture given the low volume, the age of the product formulations and the complexity of the processes involved." At the time of this notice, HIE Infrared 135-36 was available at a street price of around $12.00 a roll at US mail order outlets.
Arguably the greatest obstacle to infrared film photography has been the increasing difficulty of obtaining infrared-sensitive film. However, despite the discontinuance of HIE, other newer infrared sensitive emulsions from EFKE, ROLLEI, and ILFORD are still available, but these formulations have differing sensitivity and specifications from the venerable KODAK HIE that has been around for at least two decades. Some of these infrared films are available in 120 and larger formats as well as 35 mm, which adds flexibility to their application. With the discontinuance of Kodak HIE, Efke's IR820 film has become the only IR film on the marketneeds update with good sensitivity beyond 750 nm, the Rollei film does extend beyond 750 nm but IR sensitivity falls off very rapidly.
Color infrared transparency films have three sensitized layers that, because of the way the dyes are coupled to these layers, reproduce infrared as red, red as green, and green as blue. All three layers are sensitive to blue so the film must be used with a yellow filter, since this will block blue light but allow the remaining colors to reach the film. The health of foliage can be determined from the relative strengths of green and infrared light reflected; this shows in color infrared as a shift from red (healthy) towards magenta (unhealthy). Early color infrared films were developed in the older E-4 process, but Kodak later manufactured a color transparency film that could be developed in standard E-6 chemistry, although more accurate results were obtained by developing using the AR-5 process. In general, color infrared does not need to be refocused to the infrared index mark on the lens.
In 2007 Kodak announced that production of the 35 mm version of their color infrared film (Ektachrome Professional Infrared/EIR) would cease as there was insufficient demand. Since 2011, all formats of color infrared film have been discontinued. Specifically, Aerochrome 1443 and SO-734.
There is no currently available digital camera that will produce the same results as Kodak color infrared film although the equivalent images can be produced by taking two exposures, one infrared and the other full-color, and combining in post-production. The color images produced by digital still cameras using infrared-pass filters are not equivalent to those produced on color infrared film. The colors result from varying amounts of infrared passing through the color filters on the photo sites, further amended by the Bayer filtering. While this makes such images unsuitable for the kind of applications for which the film was used, such as remote sensing of plant health, the resulting color tonality has proved popular artistically.
Color digital infrared, as part of full spectrum photography is gaining popularity. The ease of creating a softly colored photo with infrared characteristics has found interest among hobbyists and professionals.
In 2008, Los Angeles photographer, Dean Bennici started cutting and hand rolling Aerochrome color Infrared film. All Aerochrome medium and large format which exists today came directly from his lab. The trend in infrared photography continues to gain momentum with the success of photographer Richard Mosse and multiple users all around the world.
Digital camera sensors are inherently sensitive to infrared light, which would interfere with the normal photography by confusing the autofocus calculations or softening the image (because infrared light is focused differently from visible light), or oversaturating the red channel. Also, some clothing is transparent in the infrared, leading to unintended (at least to the manufacturer) uses of video cameras. Thus, to improve image quality and protect privacy, many digital cameras employ infrared blockers. Depending on the subject matter, infrared photography may not be practical with these cameras because the exposure times become overly long, often in the range of 30 seconds, creating noise and motion blur in the final image. However, for some subject matter the long exposure does not matter or the motion blur effects actually add to the image. Some lenses will also show a 'hot spot' in the centre of the image as their coatings are optimised for visible light and not for IR.
An alternative method of DSLR infrared photography is to remove the infrared blocker in front of the sensor and replace it with a filter that removes visible light. This filter is behind the mirror, so the camera can be used normally - handheld, normal shutter speeds, normal composition through the viewfinder, and focus, all work like a normal camera. Metering works but is not always accurate because of the difference between visible and infrared refraction. When the IR blocker is removed, many lenses which did display a hotspot cease to do so, and become perfectly usable for infrared photography. Additionally, because the red, green and blue micro-filters remain and have transmissions not only in their respective color but also in the infrared, enhanced infrared color may be recorded.
Since the Bayer filters in most digital cameras absorb a significant fraction of the infrared light, these cameras are sometimes not very sensitive as infrared cameras and can sometimes produce false colors in the images. An alternative approach is to use a Foveon X3 sensor, which does not have absorptive filters on it; the Sigma SD10 DSLR has a removable IR blocking filter and dust protector, which can be simply omitted or replaced by a deep red or complete visible light blocking filter. The Sigma SD14 has an IR/UV blocking filter that can be removed/installed without tools. The result is a very sensitive digital IR camera.
While it is common to use a filter that blocks almost all visible light, the wavelength sensitivity of a digital camera without internal infrared blocking is such that a variety of artistic results can be obtained with more conventional filtration. For example, a very dark neutral density filter can be used (such as the Hoya ND400) which passes a very small amount of visible light compared to the near-infrared it allows through. Wider filtration permits an SLR viewfinder to be used and also passes more varied color information to the sensor without necessarily reducing the Wood effect. Wider filtration is however likely to reduce other infrared artefacts such as haze penetration and darkened skies. This technique mirrors the methods used by infrared film photographers where black-and-white infrared film was often used with a deep red filter rather than a visually opaque one.
Another common technique with near-infrared filters is to swap blue and red channels in software (e.g. photoshop) which retains much of the characteristic 'white foliage' while rendering skies a glorious blue.
Several Sony cameras had the so-called Night Shot facility, which physically moves the blocking filter away from the light path, which makes the cameras very sensitive to infrared light. Soon after its development, this facility was 'restricted' by Sony to make it difficult for people to take photos that saw through clothing. To do this the iris is opened fully and exposure duration is limited to long times of more than 1/30 second or so. It is possible to shoot infrared but neutral density filters must be used to reduce the camera's sensitivity and the long exposure times mean that care must be taken to avoid camera-shake artifacts.
Fuji have produced digital cameras for use in forensic criminology and medicine which have no infrared blocking filter. The first camera, designated the S3 PRO UVIR, also had extended ultraviolet sensitivity (digital sensors are usually less sensitive to UV than to IR). Optimum UV sensitivity requires special lenses, but ordinary lenses usually work well for IR. In 2007, FujiFilm introduced a new version of this camera, based on the Nikon D200/ FujiFilm S5 called the IS Pro, also able to take Nikon lenses. Fuji had earlier introduced a non-SLR infrared camera, the IS-1, a modified version of the FujiFilm FinePix S9100. Unlike the S3 PRO UVIR, the IS-1 does not offer UV sensitivity. FujiFilm restricts the sale of these cameras to professional users with their EULA specifically prohibiting "unethical photographic conduct".
Phase One digital camera backs can be ordered in an infrared modified form.
Remote sensing and thermographic cameras are sensitive to longer wavelengths of infrared (see Infrared spectrum#Commonly used sub-division scheme). They may be multispectral and use a variety of technologies which may not resemble common camera or filter designs. Cameras sensitive to longer infrared wavelengths including those used in infrared astronomy often require cooling to reduce thermally induced dark currents in the sensor (see Dark current (physics)). Lower cost uncooled thermographic digital cameras operate in the Long Wave infrared band (see Thermographic camera#Uncooled infrared detectors). These cameras are generally used for building inspection or preventative maintenance but can be used for artistic pursuits as well.

SUMMARY
Theophilus Raynsford Mann is a naturalist, occultist, Buddhist and Taoist. In 1982, Mann developed a technique for abstract photography, applied “Rayonism” into photographic works. Mann staged 32 individual, extraordinary exhibitions around Taiwan, who was the first exhibitor around Formosa. Mann’s works is the beginning of modernization in the modern abstract arts in the world. At the University of Oxford, Mann’s attractive topic was “A View of Architectural History: Towns through the Ages from Winchester through London Arrived at Oxford in England”; also an author at the University of California, Berkeley and the University of Michigan in the United States; an alumnus from Christ Church College at the University of Oxford in England, the University of Glamorgan in Wales, and National Taiwan University in Taipei on Taiwan. Mann’s works have been quoted by the scholars many times, making Mann one of the highly cited technological, artistic, and managing public administrators in the academia. Mann was listed in “Taiwan Who’s Who In Business” © 1984, 1987, 1989 Harvard Management Service.
Education in Taiwan and a Brief of Latest Generation of History in Taiwan / Formosa
In 1980, Mann obtained his postgraduate certificate from the Graduate Institute of Electrical Engineering of National Taiwan University in Taipei; successfully completed another graduate studies in Information dBase III Plus and Taiwanese Traditional Chinese Mandarin Information System at National Sun Yat-Sen University in Kaohsiung in 1989.
Early Career
In 1989, Mann instituted Mann’s Office of Electrical Engineer, he settled himself in electrical technology and industries as a chief engineer in his early years. He put his professional and precise knowledge to good account in business management. A formal business management with business relationship established to provide for regular services, dealings, and other commercial transactions and deed. He had many customers having a business and credit relationship with his firm then he was a successful engineer.
Study Abroad and Immigration into the United Kingdom
In 1998, Mann studied abroad when he arrived in Great Britain; he studied at School of Built Environment, the University of Glamorgan, Wales for a master of science in real estate appraisal. Until the summer of 2000, Mann completed an academic course on “Towns through the Ages” from Christ Church at the University of Oxford.
PHILOSOPHICAL VIEWS
Mann is a naturalist; he trusts spiritual naturalism and naturalistic spirituality, which teaches that “the unknown” created this wonderful world. “The unknown” arranged the nature with its law so that everything in nature is kept balanced and in order. However, human beings failed to control themselves, deliberately went against the law of nature, and resulted in disasters, which we deserved. He also is an occultist, a Taoist, and a Buddhist; but in Britain, he frequently goes to Christian and Catholic churches, where he makes friends with pastors and fathers as well as churchgoers. In his mind, he recognizes “Belief is truth held in the mind; faith is a fire in the heart”. He is always a freethinker, does not accept traditional, social, and religious teaching, but based on his ideas: a thought or conception that potentially and actually exists in his mind as a product of mental activity - his opinion, conviction, and principle. If people have not come across eastern classics and philosophy, we are afraid that people would never understand Theophilus Raynsford Mann. People cannot judge an eastern philosopher based on western ways of thinking. He studies I Ching discovering eastern classics of ancient origin consisting of 64 interrelated hexagrams along with commentaries. The hexagrams embody Taoist philosophy by describing all nature and human endeavour in terms of the interaction of yin and yang, and the classics may be consulted as an oracle.
Back in the 1990s when Mann just arrived at England, he had been offered places to do Ph.D. and LL.M. degrees (degree in Law and Politics of the European Union) by several western professors in the Great Britain. He has met all the requirements for postgraduate admissions to study at UK’s universities.
During his time at Oxford, he learnt a lot of British culture and folk-custom while carrying out research with many British and Western professors, experts, and archaeologists. This proves that Mann understands various aspects in British society, culture, and lifestyles. Of course, he does not fully understand about the perspectives of thinking of a typical British. For example, what would be the most valuable in life for a British person? What would a British want to gain from life? What is the goal in life for a British? Is it fortune or a lover? Alternatively, perhaps honour? On the other hand, maybe being able to travel around the world and see the world?
FAIRNESS and JUSTICE
As Theophilus Raynsford Mann’s saying are:
“Touching Fairness and Justice”
Feel good about themselves, but do not know the sufferings of the people...
Who can get easy life like them?
What is profile of modern society?
What type and style is truly solemn for this society identify?
Where “the characterization” is? Who can see? Did you see it?
《感動的公平與正義》
自我感覺良好, 不知民間疾苦...
誰能得到安逸的生活如同他們一樣？
這是個什麼樣子的社會？
這個社會認定什麼樣的類型和風格是真正莊重的?
「特徵」在那裡？誰可以看到？你看到了嗎？
Jurisprudence and Political Philosophy and Perspectives
Mann ever studied judicial review and governmental action, the impact of law and legal techniques, constitutional mechanisms for the protection of basic rights, and ensuring the integrity of commercial activity, the impact of law and legal techniques on government, policymaking, and administration, as well as the creation of markets. He tries to understand these critical trends in the political development of modern state. Mann will combine both theoretical and empirical approaches, and the conditions for democratic transition and the nature of state development in the ‘post-industrial’ era of globalisation and economic integration.
According as Mann’s legal experiences, he comprehend that “the knowledge of the law is like a deep well, out of which each man draught according to the strength of his understanding”, and, law and arbitrary power are in eternal enmity. He is also sure law and institutions are constantly tending to gravitate like clocks; they must be occasionally cleansed, and wound up, and set to true time.
The government issues a decree - an authoritative order having the force of law, which charged with putting into effect a country's laws and the administering of its functions. Any of the officials promulgate a law or put into practice relating to the government charged with the execution and administration of the nation's laws then they announce and carry out the creation of any order or new policy that will be responsible for the people.
Mann had knowledge in connexion with construction law; he also understands architectural arts, and as well learnt the forms by combining materials and parts include as an integral part concerning modern construct. I ever built urban buildings and rural architecture in different styles under new housing and building projects by the governmental administration and construction corporations.
Right now, Mann studies the problems caused by ethnic disputes and human armed conflicts in the modern society resulted code of mixed civil and criminal procedure. He wishes an agreement or a treaty to end human hostilities - the absence of war and other hostilities around the world. The interrelation and arrangement of freedom from quarrels and disagreement become harmonious relations living in peace with each other. Actually, erect peace in more friendly ways of making friendships for modern human society is comfortable in my ideal. It is like building monolithic architecture: houses and buildings for the people. Mann would like to do “something beautiful for `the unknown`”.
In the ethnic disagreement and armed conflicts as concerning the poor people and children notwithstanding they live through a bad environment on any of poor or crowded village or town in a particular manner - lived frugally. However, after years of industrialisation as a more educated population, becomes more aware of global plenum, continuing to be alive. Environmental groups are increasing and lobbing government will legislate to stop bad environmental and social practices. The establishments of human rights’ wide and untiring efforts will be alleviated people’s suffering. And as well the poor people shall meet and debate sustainable development and for a concerted government led action towards sustainability is an example that the younger generation are concerned for the future. It shall be making the younger easier for their life and make better on their lives, and help them to build a better future.
In present world, Mann really knows the full meanings of “Fundamental Human Rights and Equal Opportunities for the People”. He thinks ethics is the moral code governing the daily conduct of the individual toward those about him / her. It represents those rules or principles by which men and women live and work in a spirit of mutual confidence and service. Without going into the question of how an ethical code was formulated or why anybody should obey it, we can look at the matter in a common-sense fashion with reference to its influence upon our legal affairs. In brief, from the law point of view, a reputable ethical code embodies the qualities of accuracy, dependability, fair play, sound judgement, and service. It is based upon honesty.
No person can have an ethical code that concerns him / her alone. Living in society, as he / she must, a person encounters others whose rights must be respected as well as his / her own. An honest regard for the rights of others is an essential element of any decent code of ethics, and one that anyone must observe if anybody intends to follow that code. After all, ethics is not something apart from human beings. Indeed, there is no such thing apart from our actions and us. It is the duty, therefore, of every man and woman in legal affairs to see that his daily associations with others are truly in conformity with the plain meaning of the Ten Commandments: “Thou shalt not barratry, thou shalt not bear false witness, thou shalt not receive illegal fee and the rest”.
The knowledge Mann has, in connection with legal affairs, was usually come from his precious experiences of his past over ten year’s law and political careers. In an interval regarded as a distinct period of 1980s, he studied mixed civil and crime, and the code of mixed civil and criminal procedure for the problems caused by ethnic disputes and human armed conflicts in the modern society. He was especially one who maintains the language and customs of the group, and social security in Taiwan.
Since 30 July of 1988, Mann settled himself in law as a chief executive and scrivener at Central Legal, Real Estate, and Accounting Services Office; it is in the equivalent to a solicitor of the United Kingdom. The Office provided full legal, accounting, real estate, and commercial services to the public. He did his job as a person legally appointed by another to act as his or her agent in the transaction of business, specifically one qualified and licensed to act for plaintiffs and defendants in legal proceedings and affairs. Over and above Mann was a chairman and executive consultant at Taiwan Credit Information Company®, founded in 1994. The company offered services to the public in response to need and demand in the area of credit information.
Mann had excellent experiences in political and law work was pertaining to mixed civil and crime, the code of mixed civil and criminal procedure, construction, and commercial law abroad. The experiences of legal services related to the rights of private individuals and legal proceedings concerning these rights as distinguished. In the criminal proceedings, he did many cases for the defendants. Although an act committed or omitted in violation of a law forbidding or commanding it and for which punishment is imposed upon conviction; but he also laid legal claim, required as useful, just, proper, or necessary to the defendants under the human rights in the meantime. This provision ensures to the defendant a real voice in the subject.
The men whose judgement we respect are those who do not allow prejudices, preferences, or personalities to influence their decisions. Profit and self-aggrandisement are likewise ignored in their determination to reach an equitable and fair settlement. What are the basic principles upon which good judgement is founded? A keen intellect, a normal emotionally, a through understanding of human nature, experience of law work, sincerity, and integrity.
Developed a Technique for Abstract Photography and Abstractionist
In 1982, Mann developed a technique for abstractive photography, which applied “rayonism” to the photographic works. In November of 1984, Mann was 26-year-old, he instructed many professors and students of National Taiwan Normal University in photography of abstract impressionism and rayonnisme in Taipei, Taiwan. The word “rayonnisme” is French for rayonism - a style of abstract painting developed in 1911 in Russia.

Mann staged 32 individual, extraordinary exhibitions and annual special exhibitions on photography of abstractive image and Rayonnisme around Taiwan / Formosa. Mann was the first exhibitor around the country. All of the invited displays were by the Taiwan’s Government, cultural and artistic organisations, and sponsors. Mann’s earliest exhibition took place in the National Taiwan Arts Education Center (Museum) on 19 December 1983 when Mann was 25 years old; Mann was the youngest exhibitor in the history of the Center in any solo exhibitions. The Center that was opened in March 1957, kept a collection of Mann’s work. It is currently updating the Center’s internal organisation and strengthening co-operation with leading centers and museums around the world. Meanwhile, it widened the center’s scope to increase its emphasis on Taiwan’ regional culture and folk arts.
Modernization in the Modern Abstract Arts of Taiwan
Mann’s works is the beginning of modernization in the modern abstract arts of Taiwan, China and greater Chinese society in the world. The use of “modernisation” as a concept that is opposed to “Traditional” of “Conservative” ideas began with the approach of the 20th century. It spreads rapidly through academic circles, and was broadly accepted as a means to reform society. Chinese Manchu Qing (Ching) dynasty’s first steps toward modernisation began in the Tung-chih era (1862-1874) with the “Self-Empowerment Movement”. During the late 19th century, as late Manchu dynasty was confronted on all sides by foreign aggression, voices throughout society debated the most effective means to reform and strengthen the country. Some advocated “combining the best of East and West”, while others went so far as to call for “complete Westernisation”. Taiwan was at the centre of these waves of reform. Faced with direct threats against the island by foreign enemies, the Chinese Ching dynasty court took special steps to push Taiwan’s modernisation.
In a role just like that of a gardener wanting to create a rich and fertile environment for the seeds of culture, one in which Mann may sprout, grow and bloom. Mann aims to provide an educational stimulus for society by introducing his works - Mann can express the neo-romantic spirit deftly from various creations and supporting international artistic exchanges. Mann believes that the first step in creating such a new and independent state is the real emergence of culture and arts, for which the art and science of designing and erecting buildings, and fine arts (including photography and motion picture) of the civilization is a good measurement of success. For the foreseeable future, Mann should be continuing to forge ahead, working diligently and unceasingly towards its mission of raising China and Formosa / Taiwan’s culture in his spare time.
Became an Author and a Scholar
In 1980, Theophilus Raynsford Mann completed his first book - scenario original “The Soul's Sentimentalizing”, also named: “Hun Yun : Jin Qi Tu Rui” 電影原著《魂韻》(衿契吐蕊) then Mann was at the age of 22. In 1983, The General Library of the University of California, Berkeley in the United States of America, collected and kept Mann’s writings - scenario original 「魂韻 : 衿契吐蕊」“Hun Yun : jin qi tu rui”, included a musical composition of his own – “Sonate Nr. 1 C-dur op. 3 für Klavier (piano)”, composed on 3rd April 1977 then Mann was 18 years old. The works were published in 1980; the theme was based on “The Soul's Sentimentalizing”. Another masterpiece was an Album of Academic Work for News
Publication “Theophilus Raynsford Mann Photographic Exhibition of Rayonnisme / Rayonism”, published in 1985. The Hathi Trust Digital Library, the University of Michigan also collected and kept Mann’s writings.
Authorship
Mann’s articles and writings were published in more than 200 different kinds of domestic and foreign magazines, newspapers, and periodicals, in the period between May of 1972 and 1990s. It was all started when Mann was just 13-year-old. Many of which have been very influential. These have been quoted by Western and Eastern scholars many times in the last few years, making Mann one of the highly cited technological, artistic, and managing public administrators in the world in the late 20th and early 21st century. The Ministry of the Interior in Taiwan had registered Mann’s professional writings and given him two certificates of copyright. The numbers are 33080 and 33081 on 4th July of 1985; and Taiwan’s Gazette of The Presidential Office issue No. 4499, featured his writings on 4th September 1985.
Became an Academic and Film Director
Today, Mann is a professor at Space Time Life Research Academy, a photographer (portrait, fashion, commercial, digital, architectural, abstract photography), film director, and computer engineer now live and work in London; and most currently engage in his vocational professions of ‘Consultant of Immigration and Translations’. Mann is an author at the University of California, Berkeley, and the University of Michigan; an alumnus from Christ Church at the University of Oxford, the University of Glamorgan, and National Taiwan University in Taipei.

High Dynamic Range (HDR)
High-dynamic-range imaging (HDRI) is a high dynamic range (HDR) technique used in imaging and photography to reproduce a greater dynamic range of luminosity than is possible with standard digital imaging or photographic techniques. The aim is to present a similar range of luminance to that experienced through the human visual system. The human eye, through adaptation of the iris and other methods, adjusts constantly to adapt to a broad range of luminance present in the environment. The brain continuously interprets this information so that a viewer can see in a wide range of light conditions.
HDR images can represent a greater range of luminance levels than can be achieved using more 'traditional' methods, such as many real-world scenes containing very bright, direct sunlight to extreme shade, or very faint nebulae. This is often achieved by capturing and then combining several different, narrower range, exposures of the same subject matter. Non-HDR cameras take photographs with a limited exposure range, referred to as LDR, resulting in the loss of detail in highlights or shadows.
The two primary types of HDR images are computer renderings and images resulting from merging multiple low-dynamic-range (LDR) or standard-dynamic-range (SDR) photographs. HDR images can also be acquired using special image sensors, such as an oversampled binary image sensor.
Due to the limitations of printing and display contrast, the extended luminosity range of an HDR image has to be compressed to be made visible. The method of rendering an HDR image to a standard monitor or printing device is called tone mapping. This method reduces the overall contrast of an HDR image to facilitate display on devices or printouts with lower dynamic range, and can be applied to produce images with preserved local contrast (or exaggerated for artistic effect).
In photography, dynamic range is measured in exposure value (EV) differences (known as stops). An increase of one EV, or 'one stop', represents a doubling of the amount of light. Conversely, a decrease of one EV represents a halving of the amount of light. Therefore, revealing detail in the darkest of shadows requires high exposures, while preserving detail in very bright situations requires very low exposures. Most cameras cannot provide this range of exposure values within a single exposure, due to their low dynamic range. High-dynamic-range photographs are generally achieved by capturing multiple standard-exposure images, often using exposure bracketing, and then later merging them into a single HDR image, usually within a photo manipulation program). Digital images are often encoded in a camera's raw image format, because 8-bit JPEG encoding does not offer a wide enough range of values to allow fine transitions (and regarding HDR, later introduces undesirable effects due to lossy compression).
Any camera that allows manual exposure control can make images for HDR work, although one equipped with auto exposure bracketing (AEB) is far better suited. Images from film cameras are less suitable as they often must first be digitized, so that they can later be processed using software HDR methods.
In most imaging devices, the degree of exposure to light applied to the active element (be it film or CCD) can be altered in one of two ways: by either increasing/decreasing the size of the aperture or by increasing/decreasing the time of each exposure. Exposure variation in an HDR set is only done by altering the exposure time and not the aperture size; this is because altering the aperture size also affects the depth of field and so the resultant multiple images would be quite different, preventing their final combination into a single HDR image.
An important limitation for HDR photography is that any movement between successive images will impede or prevent success in combining them afterwards. Also, as one must create several images (often three or five and sometimes more) to obtain the desired luminance range, such a full 'set' of images takes extra time. HDR photographers have developed calculation methods and techniques to partially overcome these problems, but the use of a sturdy tripod is, at least, advised.
Some cameras have an auto exposure bracketing (AEB) feature with a far greater dynamic range than others, from the 3 EV of the Canon EOS 40D, to the 18 EV of the Canon EOS-1D Mark II. As the popularity of this imaging method grows, several camera manufactures are now offering built-in HDR features. For example, the Pentax K-7 DSLR has an HDR mode that captures an HDR image and outputs (only) a tone mapped JPEG file. The Canon PowerShot G12, Canon PowerShot S95 and Canon PowerShot S100 offer similar features in a smaller format.. Nikon's approach is called 'Active D-Lighting' which applies exposure compensation and tone mapping to the image as it comes from the sensor, with the accent being on retaing a realistic effect . Some smartphones provide HDR modes, and most mobile platforms have apps that provide HDR picture taking.
Camera characteristics such as gamma curves, sensor resolution, noise, photometric calibration and color calibration affect resulting high-dynamic-range images.
Color film negatives and slides consist of multiple film layers that respond to light differently. As a consequence, transparent originals (especially positive slides) feature a very high dynamic range
Tone mapping
Tone mapping reduces the dynamic range, or contrast ratio, of an entire image while retaining localized contrast. Although it is a distinct operation, tone mapping is often applied to HDRI files by the same software package.
Several software applications are available on the PC, Mac and Linux platforms for producing HDR files and tone mapped images. Notable titles include
Adobe Photoshop
Aurora HDR
Dynamic Photo HDR
HDR Efex Pro
HDR PhotoStudio
Luminance HDR
MagicRaw
Oloneo PhotoEngine
Photomatix Pro
PTGui
Information stored in high-dynamic-range images typically corresponds to the physical values of luminance or radiance that can be observed in the real world. This is different from traditional digital images, which represent colors as they should appear on a monitor or a paper print. Therefore, HDR image formats are often called scene-referred, in contrast to traditional digital images, which are device-referred or output-referred. Furthermore, traditional images are usually encoded for the human visual system (maximizing the visual information stored in the fixed number of bits), which is usually called gamma encoding or gamma correction. The values stored for HDR images are often gamma compressed (power law) or logarithmically encoded, or floating-point linear values, since fixed-point linear encodings are increasingly inefficient over higher dynamic ranges.
HDR images often don't use fixed ranges per color channel—other than traditional images—to represent many more colors over a much wider dynamic range. For that purpose, they don't use integer values to represent the single color channels (e.g., 0-255 in an 8 bit per pixel interval for red, green and blue) but instead use a floating point representation. Common are 16-bit (half precision) or 32-bit floating point numbers to represent HDR pixels. However, when the appropriate transfer function is used, HDR pixels for some applications can be represented with a color depth that has as few as 10–12 bits for luminance and 8 bits for chrominance without introducing any visible quantization artifacts.
History of HDR photography
The idea of using several exposures to adequately reproduce a too-extreme range of luminance was pioneered as early as the 1850s by Gustave Le Gray to render seascapes showing both the sky and the sea. Such rendering was impossible at the time using standard methods, as the luminosity range was too extreme. Le Gray used one negative for the sky, and another one with a longer exposure for the sea, and combined the two into one picture in positive.
Mid 20th century
Manual tone mapping was accomplished by dodging and burning – selectively increasing or decreasing the exposure of regions of the photograph to yield better tonality reproduction. This was effective because the dynamic range of the negative is significantly higher than would be available on the finished positive paper print when that is exposed via the negative in a uniform manner. An excellent example is the photograph Schweitzer at the Lamp by W. Eugene Smith, from his 1954 photo essay A Man of Mercy on Dr. Albert Schweitzer and his humanitarian work in French Equatorial Africa. The image took 5 days to reproduce the tonal range of the scene, which ranges from a bright lamp (relative to the scene) to a dark shadow.
Ansel Adams elevated dodging and burning to an art form. Many of his famous prints were manipulated in the darkroom with these two methods. Adams wrote a comprehensive book on producing prints called The Print, which prominently features dodging and burning, in the context of his Zone System.
With the advent of color photography, tone mapping in the darkroom was no longer possible due to the specific timing needed during the developing process of color film. Photographers looked to film manufacturers to design new film stocks with improved response, or continued to shoot in black and white to use tone mapping methods.
Color film capable of directly recording high-dynamic-range images was developed by Charles Wyckoff and EG&G "in the course of a contract with the Department of the Air Force". This XR film had three emulsion layers, an upper layer having an ASA speed rating of 400, a middle layer with an intermediate rating, and a lower layer with an ASA rating of 0.004. The film was processed in a manner similar to color films, and each layer produced a different color. The dynamic range of this extended range film has been estimated as 1:108. It has been used to photograph nuclear explosions, for astronomical photography, for spectrographic research, and for medical imaging. Wyckoff's detailed pictures of nuclear explosions appeared on the cover of Life magazine in the mid-1950s.
Late 20th century
Georges Cornuéjols and licensees of his patents (Brdi, Hymatom) introduced the principle of HDR video image, in 1986, by interposing a matricial LCD screen in front of the camera's image sensor, increasing the sensors dynamic by five stops. The concept of neighborhood tone mapping was applied to video cameras by a group from the Technion in Israel led by Dr. Oliver Hilsenrath and Prof. Y.Y.Zeevi who filed for a patent on this concept in 1988.
In February and April 1990, Georges Cornuéjols introduced the first real-time HDR camera that combined two images captured by a sensor3435 or simultaneously3637 by two sensors of the camera. This process is known as bracketing used for a video stream.
In 1991, the first commercial video camera was introduced that performed real-time capturing of multiple images with different exposures, and producing an HDR video image, by Hymatom, licensee of Georges Cornuéjols.
Also in 1991, Georges Cornuéjols introduced the HDR+ image principle by non-linear accumulation of images to increase the sensitivity of the camera: for low-light environments, several successive images are accumulated, thus increasing the signal to noise ratio.
In 1993, another commercial medical camera producing an HDR video image, by the Technion.
Modern HDR imaging uses a completely different approach, based on making a high-dynamic-range luminance or light map using only global image operations (across the entire image), and then tone mapping the result. Global HDR was first introduced in 19931 resulting in a mathematical theory of differently exposed pictures of the same subject matter that was published in 1995 by Steve Mann and Rosalind Picard.
On October 28, 1998, Ben Sarao created one of the first nighttime HDR+G (High Dynamic Range + Graphic image)of STS-95 on the launch pad at NASA's Kennedy Space Center. It consisted of four film images of the shuttle at night that were digitally composited with additional digital graphic elements. The image was first exhibited at NASA Headquarters Great Hall, Washington DC in 1999 and then published in Hasselblad Forum, Issue 3 1993, Volume 35 ISSN 0282-5449.
The advent of consumer digital cameras produced a new demand for HDR imaging to improve the light response of digital camera sensors, which had a much smaller dynamic range than film. Steve Mann developed and patented the global-HDR method for producing digital images having extended dynamic range at the MIT Media Laboratory. Mann's method involved a two-step procedure: (1) generate one floating point image array by global-only image operations (operations that affect all pixels identically, without regard to their local neighborhoods); and then (2) convert this image array, using local neighborhood processing (tone-remapping, etc.), into an HDR image. The image array generated by the first step of Mann's process is called a lightspace image, lightspace picture, or radiance map. Another benefit of global-HDR imaging is that it provides access to the intermediate light or radiance map, which has been used for computer vision, and other image processing operations.
21st century
In 2005, Adobe Systems introduced several new features in Photoshop CS2 including Merge to HDR, 32 bit floating point image support, and HDR tone mapping.
On June 30, 2016, Microsoft added support for the digital compositing of HDR images to Windows 10 using the Universal Windows Platform.
HDR sensors
Modern CMOS image sensors can often capture a high dynamic range from a single exposure. The wide dynamic range of the captured image is non-linearly compressed into a smaller dynamic range electronic representation. However, with proper processing, the information from a single exposure can be used to create an HDR image.
Such HDR imaging is used in extreme dynamic range applications like welding or automotive work. Some other cameras designed for use in security applications can automatically provide two or more images for each frame, with changing exposure. For example, a sensor for 30fps video will give out 60fps with the odd frames at a short exposure time and the even frames at a longer exposure time. Some of the sensor may even combine the two images on-chip so that a wider dynamic range without in-pixel compression is directly available to the user for display or processing.

Infrared Photography
In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum (the filter thus looks black or deep red). ("Infrared filter" may refer either to this type of filter or to one that blocks infrared but passes other wavelengths.)
When these filters are used together with infrared-sensitive film or sensors, "in-camera effects" can be obtained; false-color or black-and-white images with a dreamlike or sometimes lurid appearance known as the "Wood Effect," an effect mainly caused by foliage (such as tree leaves and grass) strongly reflecting in the same way visible light is reflected from snow. There is a small contribution from chlorophyll fluorescence, but this is marginal and is not the real cause of the brightness seen in infrared photographs. The effect is named after the infrared photography pioneer Robert W. Wood, and not after the material wood, which does not strongly reflect infrared.
The other attributes of infrared photographs include very dark skies and penetration of atmospheric haze, caused by reduced Rayleigh scattering and Mie scattering, respectively, compared to visible light. The dark skies, in turn, result in less infrared light in shadows and dark reflections of those skies from water, and clouds will stand out strongly. These wavelengths also penetrate a few millimeters into skin and give a milky look to portraits, although eyes often look black.
Until the early 20th century, infrared photography was not possible because silver halide emulsions are not sensitive to longer wavelengths than that of blue light (and to a lesser extent, green light) without the addition of a dye to act as a color sensitizer. The first infrared photographs (as distinct from spectrographs) to be published appeared in the February 1910 edition of The Century Magazine and in the October 1910 edition of the Royal Photographic Society Journal to illustrate papers by Robert W. Wood, who discovered the unusual effects that now bear his name. The RPS co-ordinated events to celebrate the centenary of this event in 2010. Wood's photographs were taken on experimental film that required very long exposures; thus, most of his work focused on landscapes. A further set of infrared landscapes taken by Wood in Italy in 1911 used plates provided for him by CEK Mees at Wratten & Wainwright. Mees also took a few infrared photographs in Portugal in 1910, which are now in the Kodak archives.
Infrared-sensitive photographic plates were developed in the United States during World War I for spectroscopic analysis, and infrared sensitizing dyes were investigated for improved haze penetration in aerial photography. After 1930, new emulsions from Kodak and other manufacturers became useful to infrared astronomy.
Infrared photography became popular with photography enthusiasts in the 1930s when suitable film was introduced commercially. The Times regularly published landscape and aerial photographs taken by their staff photographers using Ilford infrared film. By 1937 33 kinds of infrared film were available from five manufacturers including Agfa, Kodak and Ilford. Infrared movie film was also available and was used to create day-for-night effects in motion pictures, a notable example being the pseudo-night aerial sequences in the James Cagney/Bette Davis movie The Bride Came COD.
False-color infrared photography became widely practiced with the introduction of Kodak Ektachrome Infrared Aero Film and Ektachrome Infrared EIR. The first version of this, known as Kodacolor Aero-Reversal-Film, was developed by Clark and others at the Kodak for camouflage detection in the 1940s. The film became more widely available in 35mm form in the 1960s but KODAK AEROCHROME III Infrared Film 1443 has been discontinued.
Infrared photography became popular with a number of 1960s recording artists, because of the unusual results; Jimi Hendrix, Donovan, Frank and a slow shutter speed without focus compensation, however wider apertures like f/2.0 can produce sharp photos only if the lens is meticulously refocused to the infrared index mark, and only if this index mark is the correct one for the filter and film in use. However, it should be noted that diffraction effects inside a camera are greater at infrared wavelengths so that stopping down the lens too far may actually reduce sharpness.
Most apochromatic ('APO') lenses do not have an Infrared index mark and do not need to be refocused for the infrared spectrum because they are already optically corrected into the near-infrared spectrum. Catadioptric lenses do not often require this adjustment because their mirror containing elements do not suffer from chromatic aberration and so the overall aberration is comparably less. Catadioptric lenses do, of course, still contain lenses, and these lenses do still have a dispersive property.
Infrared black-and-white films require special development times but development is usually achieved with standard black-and-white film developers and chemicals (like D-76). Kodak HIE film has a polyester film base that is very stable but extremely easy to scratch, therefore special care must be used in the handling of Kodak HIE throughout the development and printing/scanning process to avoid damage to the film. The Kodak HIE film was sensitive to 900 nm.
As of November 2, 2007, "KODAK is preannouncing the discontinuance" of HIE Infrared 35 mm film stating the reasons that, "Demand for these products has been declining significantly in recent years, and it is no longer practical to continue to manufacture given the low volume, the age of the product formulations and the complexity of the processes involved." At the time of this notice, HIE Infrared 135-36 was available at a street price of around $12.00 a roll at US mail order outlets.
Arguably the greatest obstacle to infrared film photography has been the increasing difficulty of obtaining infrared-sensitive film. However, despite the discontinuance of HIE, other newer infrared sensitive emulsions from EFKE, ROLLEI, and ILFORD are still available, but these formulations have differing sensitivity and specifications from the venerable KODAK HIE that has been around for at least two decades. Some of these infrared films are available in 120 and larger formats as well as 35 mm, which adds flexibility to their application. With the discontinuance of Kodak HIE, Efke's IR820 film has become the only IR film on the marketneeds update with good sensitivity beyond 750 nm, the Rollei film does extend beyond 750 nm but IR sensitivity falls off very rapidly.
Color infrared transparency films have three sensitized layers that, because of the way the dyes are coupled to these layers, reproduce infrared as red, red as green, and green as blue. All three layers are sensitive to blue so the film must be used with a yellow filter, since this will block blue light but allow the remaining colors to reach the film. The health of foliage can be determined from the relative strengths of green and infrared light reflected; this shows in color infrared as a shift from red (healthy) towards magenta (unhealthy). Early color infrared films were developed in the older E-4 process, but Kodak later manufactured a color transparency film that could be developed in standard E-6 chemistry, although more accurate results were obtained by developing using the AR-5 process. In general, color infrared does not need to be refocused to the infrared index mark on the lens.
In 2007 Kodak announced that production of the 35 mm version of their color infrared film (Ektachrome Professional Infrared/EIR) would cease as there was insufficient demand. Since 2011, all formats of color infrared film have been discontinued. Specifically, Aerochrome 1443 and SO-734.
There is no currently available digital camera that will produce the same results as Kodak color infrared film although the equivalent images can be produced by taking two exposures, one infrared and the other full-color, and combining in post-production. The color images produced by digital still cameras using infrared-pass filters are not equivalent to those produced on color infrared film. The colors result from varying amounts of infrared passing through the color filters on the photo sites, further amended by the Bayer filtering. While this makes such images unsuitable for the kind of applications for which the film was used, such as remote sensing of plant health, the resulting color tonality has proved popular artistically.
Color digital infrared, as part of full spectrum photography is gaining popularity. The ease of creating a softly colored photo with infrared characteristics has found interest among hobbyists and professionals.
In 2008, Los Angeles photographer, Dean Bennici started cutting and hand rolling Aerochrome color Infrared film. All Aerochrome medium and large format which exists today came directly from his lab. The trend in infrared photography continues to gain momentum with the success of photographer Richard Mosse and multiple users all around the world.
Digital camera sensors are inherently sensitive to infrared light, which would interfere with the normal photography by confusing the autofocus calculations or softening the image (because infrared light is focused differently from visible light), or oversaturating the red channel. Also, some clothing is transparent in the infrared, leading to unintended (at least to the manufacturer) uses of video cameras. Thus, to improve image quality and protect privacy, many digital cameras employ infrared blockers. Depending on the subject matter, infrared photography may not be practical with these cameras because the exposure times become overly long, often in the range of 30 seconds, creating noise and motion blur in the final image. However, for some subject matter the long exposure does not matter or the motion blur effects actually add to the image. Some lenses will also show a 'hot spot' in the centre of the image as their coatings are optimised for visible light and not for IR.
An alternative method of DSLR infrared photography is to remove the infrared blocker in front of the sensor and replace it with a filter that removes visible light. This filter is behind the mirror, so the camera can be used normally - handheld, normal shutter speeds, normal composition through the viewfinder, and focus, all work like a normal camera. Metering works but is not always accurate because of the difference between visible and infrared refraction. When the IR blocker is removed, many lenses which did display a hotspot cease to do so, and become perfectly usable for infrared photography. Additionally, because the red, green and blue micro-filters remain and have transmissions not only in their respective color but also in the infrared, enhanced infrared color may be recorded.
Since the Bayer filters in most digital cameras absorb a significant fraction of the infrared light, these cameras are sometimes not very sensitive as infrared cameras and can sometimes produce false colors in the images. An alternative approach is to use a Foveon X3 sensor, which does not have absorptive filters on it; the Sigma SD10 DSLR has a removable IR blocking filter and dust protector, which can be simply omitted or replaced by a deep red or complete visible light blocking filter. The Sigma SD14 has an IR/UV blocking filter that can be removed/installed without tools. The result is a very sensitive digital IR camera.
While it is common to use a filter that blocks almost all visible light, the wavelength sensitivity of a digital camera without internal infrared blocking is such that a variety of artistic results can be obtained with more conventional filtration. For example, a very dark neutral density filter can be used (such as the Hoya ND400) which passes a very small amount of visible light compared to the near-infrared it allows through. Wider filtration permits an SLR viewfinder to be used and also passes more varied color information to the sensor without necessarily reducing the Wood effect. Wider filtration is however likely to reduce other infrared artefacts such as haze penetration and darkened skies. This technique mirrors the methods used by infrared film photographers where black-and-white infrared film was often used with a deep red filter rather than a visually opaque one.
Another common technique with near-infrared filters is to swap blue and red channels in software (e.g. photoshop) which retains much of the characteristic 'white foliage' while rendering skies a glorious blue.
Several Sony cameras had the so-called Night Shot facility, which physically moves the blocking filter away from the light path, which makes the cameras very sensitive to infrared light. Soon after its development, this facility was 'restricted' by Sony to make it difficult for people to take photos that saw through clothing. To do this the iris is opened fully and exposure duration is limited to long times of more than 1/30 second or so. It is possible to shoot infrared but neutral density filters must be used to reduce the camera's sensitivity and the long exposure times mean that care must be taken to avoid camera-shake artifacts.
Fuji have produced digital cameras for use in forensic criminology and medicine which have no infrared blocking filter. The first camera, designated the S3 PRO UVIR, also had extended ultraviolet sensitivity (digital sensors are usually less sensitive to UV than to IR). Optimum UV sensitivity requires special lenses, but ordinary lenses usually work well for IR. In 2007, FujiFilm introduced a new version of this camera, based on the Nikon D200/ FujiFilm S5 called the IS Pro, also able to take Nikon lenses. Fuji had earlier introduced a non-SLR infrared camera, the IS-1, a modified version of the FujiFilm FinePix S9100. Unlike the S3 PRO UVIR, the IS-1 does not offer UV sensitivity. FujiFilm restricts the sale of these cameras to professional users with their EULA specifically prohibiting "unethical photographic conduct".
Phase One digital camera backs can be ordered in an infrared modified form.
Remote sensing and thermographic cameras are sensitive to longer wavelengths of infrared (see Infrared spectrum#Commonly used sub-division scheme). They may be multispectral and use a variety of technologies which may not resemble common camera or filter designs. Cameras sensitive to longer infrared wavelengths including those used in infrared astronomy often require cooling to reduce thermally induced dark currents in the sensor (see Dark current (physics)). Lower cost uncooled thermographic digital cameras operate in the Long Wave infrared band (see Thermographic camera#Uncooled infrared detectors). These cameras are generally used for building inspection or preventative maintenance but can be used for artistic pursuits as well.

Preparing for medical response to disasters
By Rick Scavetta, U.S. Army Africa
NAIROBI, Kenya – Should disaster strike in East Africa, a growing partnership between U.S. Army Africa and Kenya’s military designed to improve medical preparedness could help avert crisis.
Lt. Col. John Casey, U.S. Army Africa’s deputy surgeon, recently held a familiarization event with Kenyan military medical officers to discuss techniques to plan for medical response to disasters.
“Developing a cooperative relationship with our African counterparts is an important step for us working together in the future. We are learning from each other,” Casey said. “This event brought together 17 Kenyan medical officers and enlisted soldiers from their army, navy and air force to Nairobi’s Armed Forces Memorial Hospital where we talked about plans to support stability should a disaster occur.”
During the four-day seminar, Casey, 41, of Florence, S.D., discussed the U.S. Army’s planning process for unforeseen disasters and how U.S. military medical staff undergo training to respond.
They discussed medical response to public health issues and looked at psychological aspects during disasters. They also examined the various stages of disasters, how to triage sick and injured people, plus the psychosocial needs of patients.
Kenya’s military has an established medical corps that maintains a significant capacity to support routine medical operations, said U.S. Navy Lt. Brett Hicks.
“Much of our talks focused on what is appropriate for medical personnel to do when working in a stressful environment, where the military is working civilian agencies to mitigate human suffering during both natural and man-made disasters,” said Hicks, 35, of Atlanta, Ga., a patient administration officer at the U.S. Naval Hospital in Pensacola, Fla., who last worked with Casey in 2007 on a medical mission in the Philippines.
Hicks’s lecture focused on public health issues during disasters, everything from environmental hazards to diseases people face when displaced from their homes.
“I was very impressed with Kenya’s military medical officers,” Hicks said. “They want a response framework and to better understand how the military can fit into a national or regional response.”
U.S. Army Africa, the Army service component for U.S. Africa Command, regularly deploys teams of mentors to countries in Africa to develop cooperative relationships with land forces in Africa. These teams focus on niche capabilities, such as military medicine, logistics, maintenance and security operations. U.S. Army Africa’s goal is to work with the land forces of partner nations in Africa to strengthen their capacity and increase overall security, stability and peace on the continent.
In the future, the U.S. military may work with African medical officers to focus closer on developing medical plans, to include organizing logistics required to support medical efforts during disasters, Hicks said.
While in Nairobi, Casey and Hicks also met with senior leaders at the U.S. Army Medical Research Unit – Kenya, Walter Reed Army Institute of Research unit with four decades of experience battling disease in East Africa.
“USAMRU-K offers several training and partnership opportunities that may be of interest to Kenyan military medical officers, especially in malaria diagnostics,” Casey said.
On the final day, Casey and Hicks joined their Kenyan counterparts during a visit the Regional Disaster Management Center of Excellence, where director Shem Amadi, a retired Kenyan air force colonel, shared information about ongoing preparedness training and discussed the response to Kenya’s 2007 post- election violence.
“During times of peace we prepare for uncertainties and build our capacity to meet challenges,” Amadi said. “We now look at each other as friends. Should we need to, we can put our assets together.”
The idea of a regional center came from the U.S. military and U.S. Embassy in Nairobi, Amadi said. On Aug. 15, 2005, U.S. Army Gen. John Abizaid, then-commander of U.S. Army Central Command, was on hand at the center’s opening. The tree he planted as part of the dedication is now more than 15 feet tall.
“This center is a symbol of friendship between us and the American people,” Amadi said. “We have an enduring partnership.
In September 2009, military and civilian emergency response planners from Burundi, Rwanda, Tanzania, Uganda and Kenya trained at the center on pandemic influenza intervention. Afterward, they took part in Natural Fire 10, a humanitarian and civil assistance exercise co-led by U.S. Army Africa and the Ugandan People’s Defense Force.
“This was the first example of disaster response planning at a regional level, which was then tested during Natural Fire in Kampala, Uganda. It was a great event to evaluate planning.
“Our current interactions are a step forward,” Amadi explains, as he shows Casey a photo of former U.S. President Bill Clinton shaking his hand during the disaster response effort for the 2005 Indian Ocean tsunami. “Plus, we have built a network of people and had the opportunity to share information and experiences.”

Graffiti (plural; singular graffiti or graffito, the latter rarely used except in archeology) is art that is written, painted or drawn on a wall or other surface, usually without permission and within public view. Graffiti ranges from simple written words to elaborate wall paintings, and has existed since ancient times, with examples dating back to ancient Egypt, ancient Greece, and the Roman Empire (see also mural).
Graffiti is a controversial subject. In most countries, marking or painting property without permission is considered by property owners and civic authorities as defacement and vandalism, which is a punishable crime, citing the use of graffiti by street gangs to mark territory or to serve as an indicator of gang-related activities. Graffiti has become visualized as a growing urban "problem" for many cities in industrialized nations, spreading from the New York City subway system and Philadelphia in the early 1970s to the rest of the United States and Europe and other world regions
"Graffiti" (usually both singular and plural) and the rare singular form "graffito" are from the Italian word graffiato ("scratched"). The term "graffiti" is used in art history for works of art produced by scratching a design into a surface. A related term is "sgraffito", which involves scratching through one layer of pigment to reveal another beneath it. This technique was primarily used by potters who would glaze their wares and then scratch a design into them. In ancient times graffiti were carved on walls with a sharp object, although sometimes chalk or coal were used. The word originates from Greek γράφειν—graphein—meaning "to write".
The term graffiti originally referred to the inscriptions, figure drawings, and such, found on the walls of ancient sepulchres or ruins, as in the Catacombs of Rome or at Pompeii. Historically, these writings were not considered vanadlism, which today is considered part of the definition of graffiti.
The only known source of the Safaitic language, an ancient form of Arabic, is from graffiti: inscriptions scratched on to the surface of rocks and boulders in the predominantly basalt desert of southern Syria, eastern Jordan and northern Saudi Arabia. Safaitic dates from the first century BC to the fourth century AD.
Some of the oldest cave paintings in the world are 40,000 year old ones found in Australia. The oldest written graffiti was found in ancient Rome around 2500 years ago. Most graffiti from the time was boasts about sexual experiences Graffiti in Ancient Rome was a form of communication, and was not considered vandalism.
Ancient tourists visiting the 5th-century citadel at Sigiriya in Sri Lanka write their names and commentary over the "mirror wall", adding up to over 1800 individual graffiti produced there between the 6th and 18th centuries. Most of the graffiti refer to the frescoes of semi-nude females found there. One reads:
Wet with cool dew drops
fragrant with perfume from the flowers
came the gentle breeze
jasmine and water lily
dance in the spring sunshine
side-long glances
of the golden-hued ladies
stab into my thoughts
heaven itself cannot take my mind
as it has been captivated by one lass
among the five hundred I have seen here.
Among the ancient political graffiti examples were Arab satirist poems. Yazid al-Himyari, an Umayyad Arab and Persian poet, was most known for writing his political poetry on the walls between Sajistan and Basra, manifesting a strong hatred towards the Umayyad regime and its walis, and people used to read and circulate them very widely.
Graffiti, known as Tacherons, were frequently scratched on Romanesque Scandinavian church walls. When Renaissance artists such as Pinturicchio, Raphael, Michelangelo, Ghirlandaio, or Filippino Lippi descended into the ruins of Nero's Domus Aurea, they carved or painted their names and returned to initiate the grottesche style of decoration.
There are also examples of graffiti occurring in American history, such as Independence Rock, a national landmark along the Oregon Trail.
Later, French soldiers carved their names on monuments during the Napoleonic campaign of Egypt in the 1790s. Lord Byron's survives on one of the columns of the Temple of Poseidon at Cape Sounion in Attica, Greece.
The oldest known example of graffiti "monikers" found on traincars created by hobos and railworkers since the late 1800s. The Bozo Texino monikers were documented by filmmaker Bill Daniel in his 2005 film, Who is Bozo Texino?.
In World War II, an inscription on a wall at the fortress of Verdun was seen as an illustration of the US response twice in a generation to the wrongs of the Old World:
During World War II and for decades after, the phrase "Kilroy was here" with an accompanying illustration was widespread throughout the world, due to its use by American troops and ultimately filtering into American popular culture. Shortly after the death of Charlie Parker (nicknamed "Yardbird" or "Bird"), graffiti began appearing around New York with the words "Bird Lives".
Modern graffiti art has its origins with young people in 1960s and 70s in New York City and Philadelphia. Tags were the first form of stylised contemporary graffiti. Eventually, throw-ups and pieces evolved with the desire to create larger art. Writers used spray paint and other kind of materials to leave tags or to create images on the sides subway trains. and eventually moved into the city after the NYC metro began to buy new trains and paint over graffiti.
While the art had many advocates and appreciators—including the cultural critic Norman Mailer—others, including New York City mayor Ed Koch, considered it to be defacement of public property, and saw it as a form of public blight. The ‘taggers’ called what they did ‘writing’—though an important 1974 essay by Mailer referred to it using the term ‘graffiti.’
Contemporary graffiti style has been heavily influenced by hip hop culture and the myriad international styles derived from Philadelphia and New York City Subway graffiti; however, there are many other traditions of notable graffiti in the twentieth century. Graffiti have long appeared on building walls, in latrines, railroad boxcars, subways, and bridges.
An early graffito outside of New York or Philadelphia was the inscription in London reading "Clapton is God" in reference to the guitarist Eric Clapton. Creating the cult of the guitar hero, the phrase was spray-painted by an admirer on a wall in an Islington, north London in the autumn of 1967. The graffito was captured in a photograph, in which a dog is urinating on the wall.
Films like Style Wars in the 80s depicting famous writers such as Skeme, Dondi, MinOne, and ZEPHYR reinforced graffiti's role within New York's emerging hip-hop culture. Although many officers of the New York City Police Department found this film to be controversial, Style Wars is still recognized as the most prolific film representation of what was going on within the young hip hop culture of the early 1980s. Fab 5 Freddy and Futura 2000 took hip hop graffiti to Paris and London as part of the New York City Rap Tour in 1983
Commercialization and entrance into mainstream pop culture
Main article: Commercial graffiti
With the popularity and legitimization of graffiti has come a level of commercialization. In 2001, computer giant IBM launched an advertising campaign in Chicago and San Francisco which involved people spray painting on sidewalks a peace symbol, a heart, and a penguin (Linux mascot), to represent "Peace, Love, and Linux." IBM paid Chicago and San Francisco collectively US$120,000 for punitive damages and clean-up costs.
In 2005, a similar ad campaign was launched by Sony and executed by its advertising agency in New York, Chicago, Atlanta, Philadelphia, Los Angeles, and Miami, to market its handheld PSP gaming system. In this campaign, taking notice of the legal problems of the IBM campaign, Sony paid building owners for the rights to paint on their buildings "a collection of dizzy-eyed urban kids playing with the PSP as if it were a skateboard, a paddle, or a rocking horse".
Tristan Manco wrote that Brazil "boasts a unique and particularly rich, graffiti scene ... [earning] it an international reputation as the place to go for artistic inspiration". Graffiti "flourishes in every conceivable space in Brazil's cities". Artistic parallels "are often drawn between the energy of São Paulo today and 1970s New York". The "sprawling metropolis", of São Paulo has "become the new shrine to graffiti"; Manco alludes to "poverty and unemployment ... [and] the epic struggles and conditions of the country's marginalised peoples", and to "Brazil's chronic poverty", as the main engines that "have fuelled a vibrant graffiti culture". In world terms, Brazil has "one of the most uneven distributions of income. Laws and taxes change frequently". Such factors, Manco argues, contribute to a very fluid society, riven with those economic divisions and social tensions that underpin and feed the "folkloric vandalism and an urban sport for the disenfranchised", that is South American graffiti art.
Prominent Brazilian writers include Os Gêmeos, Boleta, Nunca, Nina, Speto, Tikka, and T.Freak. Their artistic success and involvement in commercial design ventures has highlighted divisions within the Brazilian graffiti community between adherents of the cruder transgressive form of pichação and the more conventionally artistic values of the practitioners of grafite.
Graffiti in the Middle East has emerged slowly, with taggers operating in Egypt, Lebanon, the Gulf countries like Bahrain or the United Arab Emirates, Israel, and in Iran. The major Iranian newspaper Hamshahri has published two articles on illegal writers in the city with photographic coverage of Iranian artist A1one's works on Tehran walls. Tokyo-based design magazine, PingMag, has interviewed A1one and featured photographs of his work. The Israeli West Bank barrier has become a site for graffiti, reminiscent in this sense of the Berlin Wall. Many writers in Israel come from other places around the globe, such as JUIF from Los Angeles and DEVIONE from London. The religious reference "נ נח נחמ נחמן מאומן" ("Na Nach Nachma Nachman Meuman") is commonly seen in graffiti around Israel.
Graffiti has played an important role within the street art scene in the Middle East and North Africa (MENA), especially following the events of the Arab Spring of 2011 or the Sudanese Revolution of 2018/19. Graffiti is a tool of expression in the context of conflict in the region, allowing people to raise their voices politically and socially. Famous street artist Banksy has had an important effect in the street art scene in the MENA area, especially in Palestine where some of his works are located in the West Bank barrier and Bethlehem.
There are also a large number of graffiti influences in Southeast Asian countries that mostly come from modern Western culture, such as Malaysia, where graffiti have long been a common sight in Malaysia's capital city, Kuala Lumpur. Since 2010, the country has begun hosting a street festival to encourage all generations and people from all walks of life to enjoy and encourage Malaysian street culture.
The modern-day graffitists can be found with an arsenal of various materials that allow for a successful production of a piece. This includes such techniques as scribing. However, spray paint in aerosol cans is the number one medium for graffiti. From this commodity comes different styles, technique, and abilities to form master works of graffiti. Spray paint can be found at hardware and art stores and comes in virtually every color.
Stencil graffiti is created by cutting out shapes and designs in a stiff material (such as cardboard or subject folders) to form an overall design or image. The stencil is then placed on the "canvas" gently and with quick, easy strokes of the aerosol can, the image begins to appear on the intended surface.
Some of the first examples were created in 1981 by artists Blek le Rat in Paris, in 1982 by Jef Aerosol in Tours (France); by 1985 stencils had appeared in other cities including New York City, Sydney, and Melbourne, where they were documented by American photographer Charles Gatewood and Australian photographer Rennie Ellis
Tagging is the practice of someone spray-painting "their name, initial or logo onto a public surface" in a handstyle unique to the writer. Tags were the first form of modern graffiti.
Modern graffiti art often incorporates additional arts and technologies. For example, Graffiti Research Lab has encouraged the use of projected images and magnetic light-emitting diodes (throwies) as new media for graffitists. yarnbombing is another recent form of graffiti. Yarnbombers occasionally target previous graffiti for modification, which had been avoided among the majority of graffitists.
Theories on the use of graffiti by avant-garde artists have a history dating back at least to the Asger Jorn, who in 1962 painting declared in a graffiti-like gesture "the avant-garde won't give up"
Many contemporary analysts and even art critics have begun to see artistic value in some graffiti and to recognize it as a form of public art. According to many art researchers, particularly in the Netherlands and in Los Angeles, that type of public art is, in fact an effective tool of social emancipation or, in the achievement of a political goal
In times of conflict, such murals have offered a means of communication and self-expression for members of these socially, ethnically, or racially divided communities, and have proven themselves as effective tools in establishing dialog and thus, of addressing cleavages in the long run. The Berlin Wall was also extensively covered by graffiti reflecting social pressures relating to the oppressive Soviet rule over the GDR.
Many artists involved with graffiti are also concerned with the similar activity of stenciling. Essentially, this entails stenciling a print of one or more colors using spray-paint. Recognized while exhibiting and publishing several of her coloured stencils and paintings portraying the Sri Lankan Civil War and urban Britain in the early 2000s, graffitists Mathangi Arulpragasam, aka M.I.A., has also become known for integrating her imagery of political violence into her music videos for singles "Galang" and "Bucky Done Gun", and her cover art. Stickers of her artwork also often appear around places such as London in Brick Lane, stuck to lamp posts and street signs, she having become a muse for other graffitists and painters worldwide in cities including Seville.
Graffitist believes that art should be on display for everyone in the public eye or in plain sight, not hidden away in a museum or a gallery. Art should color the streets, not the inside of some building. Graffiti is a form of art that cannot be owned or bought. It does not last forever, it is temporary, yet one of a kind. It is a form of self promotion for the artist that can be displayed anywhere form sidewalks, roofs, subways, building wall, etc. Art to them is for everyone and should be showed to everyone for free.
Graffiti is a way of communicating and a way of expressing what one feels in the moment. It is both art and a functional thing that can warn people of something or inform people of something. However, graffiti is to some people a form of art, but to some a form of vandalism. And many graffitists choose to protect their identities and remain anonymous or to hinder prosecution.
With the commercialization of graffiti (and hip hop in general), in most cases, even with legally painted "graffiti" art, graffitists tend to choose anonymity. This may be attributed to various reasons or a combination of reasons. Graffiti still remains the one of four hip hop elements that is not considered "performance art" despite the image of the "singing and dancing star" that sells hip hop culture to the mainstream. Being a graphic form of art, it might also be said that many graffitists still fall in the category of the introverted archetypal artist.
Banksy is one of the world's most notorious and popular street artists who continues to remain faceless in today's society. He is known for his political, anti-war stencil art mainly in Bristol, England, but his work may be seen anywhere from Los Angeles to Palestine. In the UK, Banksy is the most recognizable icon for this cultural artistic movement and keeps his identity a secret to avoid arrest. Much of Banksy's artwork may be seen around the streets of London and surrounding suburbs, although he has painted pictures throughout the world, including the Middle East, where he has painted on Israel's controversial West Bank barrier with satirical images of life on the other side. One depicted a hole in the wall with an idyllic beach, while another shows a mountain landscape on the other side. A number of exhibitions also have taken place since 2000, and recent works of art have fetched vast sums of money. Banksy's art is a prime example of the classic controversy: vandalism vs. art. Art supporters endorse his work distributed in urban areas as pieces of art and some councils, such as Bristol and Islington, have officially protected them, while officials of other areas have deemed his work to be vandalism and have removed it.
Pixnit is another artist who chooses to keep her identity from the general public. Her work focuses on beauty and design aspects of graffiti as opposed to Banksy's anti-government shock value. Her paintings are often of flower designs above shops and stores in her local urban area of Cambridge, Massachusetts. Some store owners endorse her work and encourage others to do similar work as well. "One of the pieces was left up above Steve's Kitchen, because it looks pretty awesome"- Erin Scott, the manager of New England Comics in Allston, Massachusetts.
Graffiti artists may become offended if photographs of their art are published in a commercial context without their permission. In March 2020, the Finnish graffiti artist Psyke expressed his displeasure at the newspaper Ilta-Sanomat publishing a photograph of a Peugeot 208 in an article about new cars, with his graffiti prominently shown on the background. The artist claims he does not want his art being used in commercial context, not even if he were to receive compensation.
Territorial graffiti marks urban neighborhoods with tags and logos to differentiate certain groups from others. These images are meant to show outsiders a stern look at whose turf is whose. The subject matter of gang-related graffiti consists of cryptic symbols and initials strictly fashioned with unique calligraphies. Gang members use graffiti to designate membership throughout the gang, to differentiate rivals and associates and, most commonly, to mark borders which are both territorial and ideological.
Graffiti has been used as a means of advertising both legally and illegally. Bronx-based TATS CRU has made a name for themselves doing legal advertising campaigns for companies such as Coca-Cola, McDonald's, Toyota, and MTV. In the UK, Covent Garden's Boxfresh used stencil images of a Zapatista revolutionary in the hopes that cross referencing would promote their store.
Smirnoff hired artists to use reverse graffiti (the use of high pressure hoses to clean dirty surfaces to leave a clean image in the surrounding dirt) to increase awareness of their product.
Graffiti often has a reputation as part of a subculture that rebels against authority, although the considerations of the practitioners often diverge and can relate to a wide range of attitudes. It can express a political practice and can form just one tool in an array of resistance techniques. One early example includes the anarcho-punk band Crass, who conducted a campaign of stenciling anti-war, anarchist, feminist, and anti-consumerist messages throughout the London Underground system during the late 1970s and early 1980s. In Amsterdam graffiti was a major part of the punk scene. The city was covered with names such as "De Zoot", "Vendex", and "Dr Rat". To document the graffiti a punk magazine was started that was called Gallery Anus. So when hip hop came to Europe in the early 1980s there was already a vibrant graffiti culture.
The student protests and general strike of May 1968 saw Paris bedecked in revolutionary, anarchistic, and situationist slogans such as L'ennui est contre-révolutionnaire ("Boredom is counterrevolutionary") and Lisez moins, vivez plus ("Read less, live more"). While not exhaustive, the graffiti gave a sense of the 'millenarian' and rebellious spirit, tempered with a good deal of verbal wit, of the strikers.
I think graffiti writing is a way of defining what our generation is like. Excuse the French, we're not a bunch of p---- artists. Traditionally artists have been considered soft and mellow people, a little bit kooky. Maybe we're a little bit more like pirates that way. We defend our territory, whatever space we steal to paint on, we defend it fiercely.
The developments of graffiti art which took place in art galleries and colleges as well as "on the street" or "underground", contributed to the resurfacing in the 1990s of a far more overtly politicized art form in the subvertising, culture jamming, or tactical media movements. These movements or styles tend to classify the artists by their relationship to their social and economic contexts, since, in most countries, graffiti art remains illegal in many forms except when using non-permanent paint. Since the 1990s with the rise of Street Art, a growing number of artists are switching to non-permanent paints and non-traditional forms of painting.
Contemporary practitioners, accordingly, have varied and often conflicting practices. Some individuals, such as Alexander Brener, have used the medium to politicize other art forms, and have used the prison sentences enforced on them as a means of further protest. The practices of anonymous groups and individuals also vary widely, and practitioners by no means always agree with each other's practices. For example, the anti-capitalist art group the Space Hijackers did a piece in 2004 about the contradiction between the capitalistic elements of Banksy and his use of political imagery.
Berlin human rights activist Irmela Mensah-Schramm has received global media attention and numerous awards for her 35-year campaign of effacing neo-Nazi and other right-wing extremist graffiti throughout Germany, often by altering hate speech in humorous ways.
In Serbian capital, Belgrade, the graffiti depicting a uniformed former general of Serb army and war criminal, convicted at ICTY for war crimes and crimes against humanity, including genocide and ethnic cleansing in Bosnian War, Ratko Mladić, appeared in a military salute alongside the words "General, thank to your mother". Aleks Eror, Berlin-based journalist, explains how "veneration of historical and wartime figures" through street art is not a new phenomenon in the region of former Yugoslavia, and that "in most cases is firmly focused on the future, rather than retelling the past". Eror is not only analyst pointing to danger of such an expressions for the region's future. In a long expose on the subject of Bosnian genocide denial, at Balkan Diskurs magazine and multimedia platform website, Kristina Gadže and Taylor Whitsell referred to these experiences as a young generations' "cultural heritage", in which young are being exposed to celebration and affirmation of war-criminals as part of their "formal education" and "inheritance".
There are numerous examples of genocide denial through celebration and affirmation of war criminals throughout the region of Western Balkans inhabited by Serbs using this form of artistic expression. Several more of these graffiti are found in Serbian capital, and many more across Serbia and Bosnian and Herzegovinian administrative entity, Republika Srpska, which is the ethnic Serbian majority enclave. Critics point that Serbia as a state, is willing to defend the mural of convicted war criminal, and have no intention to react on cases of genocide denial, noting that Interior Minister of Serbia, Aleksandar Vulin decision to ban any gathering with an intent to remove the mural, with the deployment of riot police, sends the message of "tacit endorsement". Consequently, on 9 November 2021, Serbian heavy police in riot gear, with graffiti creators and their supporters, blocked the access to the mural to prevent human rights groups and other activists to paint over it and mark the International Day Against Fascism and Antisemitism in that way, and even arrested two civic activist for throwing eggs at the graffiti.
Graffiti may also be used as an offensive expression. This form of graffiti may be difficult to identify, as it is mostly removed by the local authority (as councils which have adopted strategies of criminalization also strive to remove graffiti quickly). Therefore, existing racist graffiti is mostly more subtle and at first sight, not easily recognized as "racist". It can then be understood only if one knows the relevant "local code" (social, historical, political, temporal, and spatial), which is seen as heteroglot and thus a 'unique set of conditions' in a cultural context.
A spatial code for example, could be that there is a certain youth group in an area that is engaging heavily in racist activities. So, for residents (knowing the local code), a graffiti containing only the name or abbreviation of this gang already is a racist expression, reminding the offended people of their gang activities. Also a graffiti is in most cases, the herald of more serious criminal activity to come. A person who does not know these gang activities would not be able to recognize the meaning of this graffiti. Also if a tag of this youth group or gang is placed on a building occupied by asylum seekers, for example, its racist character is even stronger.
By making the graffiti less explicit (as adapted to social and legal constraints), these drawings are less likely to be removed, but do not lose their threatening and offensive character.
Elsewhere, activists in Russia have used painted caricatures of local officials with their mouths as potholes, to show their anger about the poor state of the roads. In Manchester, England, a graffitists painted obscene images around potholes, which often resulted in them being repaired within 48 hours.
In the early 1980s, the first art galleries to show graffitists to the public were Fashion Moda in the Bronx, Now Gallery and Fun Gallery, both in the East Village, Manhattan.
A 2006 exhibition at the Brooklyn Museum displayed graffiti as an art form that began in New York's outer boroughs and reached great heights in the early 1980s with the work of Crash, Lee, Daze, Keith Haring, and Jean-Michel Basquiat. It displayed 22 works by New York graffitists, including Crash, Daze, and Lady Pink. In an article about the exhibition in the magazine Time Out, curator Charlotta Kotik said that she hoped the exhibition would cause viewers to rethink their assumptions about graffiti.
From the 1970s onwards, Burhan Doğançay photographed urban walls all over the world; these he then archived for use as sources of inspiration for his painterly works. The project today known as "Walls of the World" grew beyond even his own expectations and comprises about 30,000 individual images. It spans a period of 40 years across five continents and 114 countries. In 1982, photographs from this project comprised a one-man exhibition titled "Les murs murmurent, ils crient, ils chantent ..." (The walls whisper, shout and sing ...) at the Centre Georges Pompidou in Paris.
In Australia, art historians have judged some local graffiti of sufficient creative merit to rank them firmly within the arts. Oxford University Press's art history text Australian Painting 1788–2000 concludes with a long discussion of graffiti's key place within contemporary visual culture, including the work of several Australian practitioners.
Between March and April 2009, 150 artists exhibited 300 pieces of graffiti at the Grand Palais in Paris.
Spray paint has many negative environmental effects. The paint contains toxic chemicals, and the can uses volatile hydrocarbon gases to spray the paint onto a surface.
Volatile organic compound (VOC) leads to ground level ozone formation and most of graffiti related emissions are VOCs. A 2010 paper estimates 4,862 tons of VOCs were released in the United States in activities related to graffiti.
In China, Mao Zedong in the 1920s used revolutionary slogans and paintings in public places to galvanize the country's communist movement.
Based on different national conditions, many people believe that China's attitude towards Graffiti is fierce, but in fact, according to Lance Crayon in his film Spray Paint Beijing: Graffiti in the Capital of China, Graffiti is generally accepted in Beijing, with artists not seeing much police interference. Political and religiously sensitive graffiti, however, is not allowed.
In Hong Kong, Tsang Tsou Choi was known as the King of Kowloon for his calligraphy graffiti over many years, in which he claimed ownership of the area. Now some of his work is preserved officially.
In Taiwan, the government has made some concessions to graffitists. Since 2005 they have been allowed to freely display their work along some sections of riverside retaining walls in designated "Graffiti Zones". From 2007, Taipei's department of cultural affairs also began permitting graffiti on fences around major public construction sites. Department head Yong-ping Lee (李永萍) stated, "We will promote graffiti starting with the public sector, and then later in the private sector too. It's our goal to beautify the city with graffiti". The government later helped organize a graffiti contest in Ximending, a popular shopping district. graffitists caught working outside of these designated areas still face fines up to NT$6,000 under a department of environmental protection regulation. However, Taiwanese authorities can be relatively lenient, one veteran police officer stating anonymously, "Unless someone complains about vandalism, we won't get involved. We don't go after it proactively."
In 1993, after several expensive cars in Singapore were spray-painted, the police arrested a student from the Singapore American School, Michael P. Fay, questioned him, and subsequently charged him with vandalism. Fay pleaded guilty to vandalizing a car in addition to stealing road signs. Under the 1966 Vandalism Act of Singapore, originally passed to curb the spread of communist graffiti in Singapore, the court sentenced him to four months in jail, a fine of S$3,500 (US$2,233), and a caning. The New York Times ran several editorials and op-eds that condemned the punishment and called on the American public to flood the Singaporean embassy with protests. Although the Singapore government received many calls for clemency, Fay's caning took place in Singapore on 5 May 1994. Fay had originally received a sentence of six strokes of the cane, but the presiding president of Singapore, Ong Teng Cheong, agreed to reduce his caning sentence to four lashes.
In South Korea, Park Jung-soo was fined two million South Korean won by the Seoul Central District Court for spray-painting a rat on posters of the G-20 Summit a few days before the event in November 2011. Park alleged that the initial in "G-20" sounds like the Korean word for "rat", but Korean government prosecutors alleged that Park was making a derogatory statement about the president of South Korea, Lee Myung-bak, the host of the summit. This case led to public outcry and debate on the lack of government tolerance and in support of freedom of expression. The court ruled that the painting, "an ominous creature like a rat" amounts to "an organized criminal activity" and upheld the fine while denying the prosecution's request for imprisonment for Park.
In Europe, community cleaning squads have responded to graffiti, in some cases with reckless abandon, as when in 1992 in France a local Scout group, attempting to remove modern graffiti, damaged two prehistoric paintings of bison in the Cave of Mayrière supérieure near the French village of Bruniquel in Tarn-et-Garonne, earning them the 1992 Ig Nobel Prize in archeology.
In September 2006, the European Parliament directed the European Commission to create urban environment policies to prevent and eliminate dirt, litter, graffiti, animal excrement, and excessive noise from domestic and vehicular music systems in European cities, along with other concerns over urban life.
In Budapest, Hungary, both a city-backed movement called I Love Budapest and a special police division tackle the problem, including the provision of approved areas.
The Anti-social Behaviour Act 2003 became Britain's latest anti-graffiti legislation. In August 2004, the Keep Britain Tidy campaign issued a press release calling for zero tolerance of graffiti and supporting proposals such as issuing "on the spot" fines to graffiti offenders and banning the sale of aerosol paint to anyone under the age of 16. The press release also condemned the use of graffiti images in advertising and in music videos, arguing that real-world experience of graffiti stood far removed from its often-portrayed "cool" or "edgy'" image.
To back the campaign, 123 Members of Parliament (MPs) (including then Prime Minister Tony Blair), signed a charter which stated: "Graffiti is not art, it's crime. On behalf of my constituents, I will do all I can to rid our community of this problem."
In the UK, city councils have the power to take action against the owner of any property that has been defaced under the Anti-social Behaviour Act 2003 (as amended by the Clean Neighbourhoods and Environment Act 2005) or, in certain cases, the Highways Act. This is often used against owners of property that are complacent in allowing protective boards to be defaced so long as the property is not damaged.
In July 2008, a conspiracy charge was used to convict graffitists for the first time. After a three-month police surveillance operation, nine members of the DPM crew were convicted of conspiracy to commit criminal damage costing at least £1 million. Five of them received prison sentences, ranging from eighteen months to two years. The unprecedented scale of the investigation and the severity of the sentences rekindled public debate over whether graffiti should be considered art or crime.
Some councils, like those of Stroud and Loerrach, provide approved areas in the town where graffitists can showcase their talents, including underpasses, car parks, and walls that might otherwise prove a target for the "spray and run".
Graffiti Tunnel, University of Sydney at Camperdown (2009)
In an effort to reduce vandalism, many cities in Australia have designated walls or areas exclusively for use by graffitists. One early example is the "Graffiti Tunnel" located at the Camperdown Campus of the University of Sydney, which is available for use by any student at the university to tag, advertise, poster, and paint. Advocates of this idea suggest that this discourages petty vandalism yet encourages artists to take their time and produce great art, without worry of being caught or arrested for vandalism or trespassing.[108][109] Others disagree with this approach, arguing that the presence of legal graffiti walls does not demonstrably reduce illegal graffiti elsewhere. Some local government areas throughout Australia have introduced "anti-graffiti squads", who clean graffiti in the area, and such crews as BCW (Buffers Can't Win) have taken steps to keep one step ahead of local graffiti cleaners.
Many state governments have banned the sale or possession of spray paint to those under the age of 18 (age of majority). However, a number of local governments in Victoria have taken steps to recognize the cultural heritage value of some examples of graffiti, such as prominent political graffiti. Tough new graffiti laws have been introduced in Australia with fines of up to A$26,000 and two years in prison.
Melbourne is a prominent graffiti city of Australia with many of its lanes being tourist attractions, such as Hosier Lane in particular, a popular destination for photographers, wedding photography, and backdrops for corporate print advertising. The Lonely Planet travel guide cites Melbourne's street as a major attraction. All forms of graffiti, including sticker art, poster, stencil art, and wheatpasting, can be found in many places throughout the city. Prominent street art precincts include; Fitzroy, Collingwood, Northcote, Brunswick, St. Kilda, and the CBD, where stencil and sticker art is prominent. As one moves farther away from the city, mostly along suburban train lines, graffiti tags become more prominent. Many international artists such as Banksy have left their work in Melbourne and in early 2008 a perspex screen was installed to prevent a Banksy stencil art piece from being destroyed, it has survived since 2003 through the respect of local street artists avoiding posting over it, although it has recently had paint tipped over it.
In February 2008 Helen Clark, the New Zealand prime minister at that time, announced a government crackdown on tagging and other forms of graffiti vandalism, describing it as a destructive crime representing an invasion of public and private property. New legislation subsequently adopted included a ban on the sale of paint spray cans to persons under 18 and increases in maximum fines for the offence from NZ$200 to NZ$2,000 or extended community service. The issue of tagging become a widely debated one following an incident in Auckland during January 2008 in which a middle-aged property owner stabbed one of two teenage taggers to death and was subsequently convicted of manslaughter.
Graffiti databases have increased in the past decade because they allow vandalism incidents to be fully documented against an offender and help the police and prosecution charge and prosecute offenders for multiple counts of vandalism. They also provide law enforcement the ability to rapidly search for an offender's moniker or tag in a simple, effective, and comprehensive way. These systems can also help track costs of damage to a city to help allocate an anti-graffiti budget. The theory is that when an offender is caught putting up graffiti, they are not just charged with one count of vandalism; they can be held accountable for all the other damage for which they are responsible. This has two main benefits for law enforcement. One, it sends a signal to the offenders that their vandalism is being tracked. Two, a city can seek restitution from offenders for all the damage that they have committed, not merely a single incident. These systems give law enforcement personnel real-time, street-level intelligence that allows them not only to focus on the worst graffiti offenders and their damage, but also to monitor potential gang violence that is associated with the graffiti.
Many restrictions of civil gang injunctions are designed to help address and protect the physical environment and limit graffiti. Provisions of gang injunctions include things such as restricting the possession of marker pens, spray paint cans, or other sharp objects capable of defacing private or public property; spray painting, or marking with marker pens, scratching, applying stickers, or otherwise applying graffiti on any public or private property, including, but not limited to the street, alley, residences, block walls, and fences, vehicles or any other real or personal property. Some injunctions contain wording that restricts damaging or vandalizing both public and private property, including but not limited to any vehicle, light fixture, door, fence, wall, gate, window, building, street sign, utility box, telephone box, tree, or power pole.
To help address many of these issues, many local jurisdictions have set up graffiti abatement hotlines, where citizens can call in and report vandalism and have it removed. San Diego's hotline receives more than 5,000 calls per year, in addition to reporting the graffiti, callers can learn more about prevention. One of the complaints about these hotlines is the response time; there is often a lag time between a property owner calling about the graffiti and its removal. The length of delay should be a consideration for any jurisdiction planning on operating a hotline. Local jurisdictions must convince the callers that their complaint of vandalism will be a priority and cleaned off right away. If the jurisdiction does not have the resources to respond to complaints in a timely manner, the value of the hotline diminishes. Crews must be able to respond to individual service calls made to the graffiti hotline as well as focus on cleanup near schools, parks, and major intersections and transit routes to have the biggest impact. Some cities offer a reward for information leading to the arrest and prosecution of suspects for tagging or graffiti related vandalism. The amount of the reward is based on the information provided, and the action taken.
When police obtain search warrants in connection with a vandalism investigation, they are often seeking judicial approval to look for items such as cans of spray paint and nozzles from other kinds of aerosol sprays; etching tools, or other sharp or pointed objects, which could be used to etch or scratch glass and other hard surfaces; permanent marking pens, markers, or paint sticks; evidence of membership or affiliation with any gang or tagging crew; paraphernalia including any reference to "(tagger's name)"; any drawings, writing, objects, or graffiti depicting taggers' names, initials, logos, monikers, slogans, or any mention of tagging crew membership; and any newspaper clippings relating to graffiti crime.

It’s been quit a week. Monday I got together with two good friends that I have know for 40 years, but haven’t seen for a long time. It was the first time in 20 years that all three of us have been together. Tuesday I turned 65, and Wednesday morning I closed on my house that has been in the building process since October. After I closed on the house I stopped by the grocery store, and while I was checking out, a clerk approched my with a bucket full of flower bouquets and asked if I’d like one. They were “expired” and he was giving them away so that they wouldn’t have to be thrown out. “How wonderful!” I thought. What a great way to celebrate! The flowers were bright and colorful, so I thought they would make a good subject for the Orton Effect. I used the Orton Effect editing tool in PicMonkey.
Please forgive my lack of comments and involvement the past few weeks. I am extremely busy packing, getting my house ready to sell, and getting ready to move into my newly built home. Photography and moving do not blend well! I won’t be actually moving in until mid May, but will be moving boxes and things in gradually. It’s an exciting time, but I’ll be gald when it’s all over and I can get back to my photography.
