The Trans-Arabian Pipe Line (also known as the Tapline) was conceived by American companies as a faster, cheaper, and safer alternative to the export of Saudi Arabian oil by ship around the Arabian Peninsula. Its origins lay in US-government coordinated efforts to replace the enormous drain on American reserves in ‘oiling’ the second world war. The Tapline was constructed between 1947 and 1950 as a joint venture of Standard Oil of New Jersey, the Socony-Vacuum Oil Company (both now merged into ExxonMobil), the Texas Company, and Standard Oil of California (now Texaco and its parent company Chevron, respectively). The pipeline was planned to run in a direct line from the Abqaiq oil field to Haifa, then in British-administered Palestine. Yet as the disputed 1947 United Nations Partition Plan divided Palestine into Arab and Israeli sections, a diversion had to be made in the route. The final stretch of the 1214 km line thus headed off at an angle through Jordan and Syria, and terminated in southern Lebanon. Oil exports flowed from 1950 until the Lebanese Civil War broke out in 1975. The Tapline later supplied oil exclusively to Jordan until Saudi Arabia stopped the agreement in 1990 in response to Jordanian support for Iraq during the first Gulf War. The pipeline has lain dormant ever since.
Crossing galleries 2 and 3, Rayyane Tabet’s Steel Rings (2013) addresses the pipeline as a form of line drawing. The artist distilled his exhaustive research into the history of the Tapline to focus on the abstract and geometric qualities of what was a remarkable feat of engineering and logistics. Tabet’s primary interest lies in the Tapline’s route as a cartographic vector, and the physical presence of a tube of steel that slices through five political entities. The steel rings replicate the scale of the pipeline in section. Each ring is engraved with the longitude, latitude and elevation corresponding to a kilometre-marker of the pipeline’s path. Three Logos (2013) evokes the numerous mergers and rebrandings of the American corporations involved. The blue oval of the Esso logo (originally a brand of Standard Oil), intertwines with the red star of Texaco and the winged horse of Mobil.

Lithography is a printing technique discovered around 1796 by the Bavarian playwright Alois Senefelder (1771–1834) as an alternative to costly copperplate engraving. Its name derives from the Latin for stone, litho, and mark, graph. After drawing with greasy crayon on the surface of the local smooth limestone, Senefelder found that images could be repeatedly inked and printed on paper. Later refinements of the technique led to a broad range of possibilities for reproducing commercial and artistic images, and the development of offset printing. It is no coincidence that all known fossil specimens of the early bird Archaeopteryx lithographica have been found in Senefelder’s Bavaria—the exceptionally fine limestone mined for lithographic printing also preserved highly detailed imprints of Jurassic life.
Touchpad comprises a dozen stone slabs once used for lithography. As printing houses closed or upgraded their presses, many slabs were discarded and were often used as paving. Tracing this history of obsolescence from inky images to ghostly footprints, MartÃn Llavaneras is interested in these surfaces as lithic tactile interfaces.

I would normally not have processed this, much less post it, but when I was looking at the image as a whole, the shallow depth of field in the sand and sea shells under this Egret was just something that jumped out at me. So... I'm sharing it with folks who can geek on out it.

Rule of composition: Depth
- Dimension is created in this photo as it separates it into 3 different parts which are the foreground, middle ground, and background. The front roof is the foreground; the roof behind it is the middle ground and the sky is the background.
Why is this a good photo?
- It is taken from a unique angle and perspective. The special lighting of the sky makes the subject(roof) more obvious and also the rule of depth more focused on.
How can this be improved?
- Crop the upper part of the photo to focus even more on the roof.
The Aslan Pasha Mosque seen in the distance from Nisi, the island in lake Pamvotis, Ioannina, Epirus, Greece. The mosque built in 1618 at the location of the church of St. John, sealed the Ottoman rule after the failed revolution of Dionysius the Philosopher in 1611. It retained its function after the liberation of the city in 1913, serving the muslim minority of Ioannina until the population exchange in 1924 following the end of Greco-Turkish War (1919–1922). Since 1933 it houses the Municipal Ethnographic Museum. Its minaret, which is broken in this photo, was damaged in September of 2018 from a medicane (Mediterranean tropical-like cyclone) and its repair has been completed in August 2019.

This photo was taken with a 50mm prime lens with shutter speed of 1/4000 seconds and f/3.2. This is a picture representing the motion of water from a hose. The shutter speed of 1/4000s was enough to freeze the motion of the water.
No processing other than slightly boosted shadows when converting from RAW, and very slight edge vignetting added in Picnik. I'm beginning to really like this EF 50mm f/1.8 II lens.
I have been trying to teach myself to look for ways to add more depth to pictures.
I figure if you consider the moon to be the background then this picture has the most depth you can get without actually digging a hole and standing in it.

Lake Kivu with Goma in the background
Lake Kivu is one of the African Great Lakes. It lies on the border between the Democratic Republic of the Congo and Rwanda, and is in the Albertine Rift, the western branch of the East African Rift. Lake Kivu empties into the Ruzizi River, which flows southwards into Lake Tanganyika. The name comes from kivu which means "lake" in some Bantu languages, just like the words tanganyika or nyanza.[citation needed]

People on the shore at Gisenyi
The first European to visit the lake was German Count Adolf von Götzen in 1894. Since then it has been caught up in the conflict between Hutu and Tutsi people in Rwanda, and their allies in DR Congo, which led to the 1994 Rwandan Genocide and the First and Second Congo Wars. Lake Kivu gained notoriety as a place where many of the victims of the genocide were dumped.
Geography
The lake covers a total surface area of some 2,700 km2 (1,040 sq mi) and stands at a height of 1,460 metres (4,790 ft) above sea level. Some 1 370 km2 or 58% of the lake's waters lie within DRC borders. The lake bed sits upon a rift valley that is slowly being pulled apart, causing volcanic activity in the area, and making it particularly deep: its maximum depth of 480 m (1,575 ft) is ranked eighteenth in the world.
The world's tenth-largest inland island, Idjwi, lies in Lake Kivu, as does the tiny island of Tshegera, which also lies within the boundaries of Virunga National Park; while settlements on its shore include Bukavu, Kabare, Kalehe, Sake, and Goma in Congo, and Gisenyi, Kibuye, and Cyangugu in Rwanda.
Chemistry
Lake Kivu is a fresh water lake and, along with Cameroonian Lake Nyos and Lake Monoun, is one of three that experience limnic eruptions. Around the lake, geologists found evidence of massive biological extinctions about every thousand years, caused by outgassing events. The trigger for lake overturns in Lake Kivu's case is unknown, but volcanic activity is suspected. The gaseous chemical composition of exploding lakes is unique to each lake; in Lake Kivu's case, methane and carbon dioxide due to lake water interaction with a volcano. The amount of methane is estimated to be 65 cubic kilometers (if burnt over one year, it would give an average power of about 100 gigawatts for the whole period). There is also an estimated 256 cubic kilometers of carbon dioxide. The water temperature is 24°C, and the pH level is about 8.6.[2] The methane is reported to be produced by microbial reduction of the volcanic CO2.[3] The risk from a possible Lake Kivu overturn is catastrophic, dwarfing other documented lake overturns at Lakes Nyos and Monoun, because of the approximately two million people living in the lake basin.
Cores from the Bukavu Bay area of the lake reveal that the bottom has layered deposits of the rare mineral monohydrocalcite interlain with diatoms, on top of sapropelic sediments with high pyrite content. These are found at three different intervals. The sapropelic layers are believed to be related to hydrothermal discharge and the diatoms to a bloom which reduced the carbon dioxide levels low enough to precipitiate monohydrocalcite.[4]
Scientists hypothesize that sufficient volcanic interaction with the lake's bottom water that has high gas concentrations would heat water, force the methane out of the water, spark a methane explosion, and trigger a nearly simultaneous release of carbon dioxide.[5][6] The carbon dioxide would then suffocate large numbers of people in the lake basin as the gases roll off the lake surface. It is also possible that the lake could spawn lake tsunamis as gas explodes out of it.[7][8]
The risk posed by Lake Kivu began to be understood during the analysis of more recent events at Lake Nyos. Lake Kivu's methane was originally thought to be merely a cheap natural resource for export, and for the generation of cheap power. Once the mechanisms that caused lake overturns began to be understood, so did awareness of the risk the lake posed to the local population.
An experimental vent pipe was installed at Lake Nyos in 2001 to remove gas from the deep water, but such a solution for the much larger Lake Kivu would be considerably more expensive. No plan has been initiated to reduce the risk posed by Lake Kivu.[dubious – discuss] The approximately 500 million tonnes of carbon dioxide in the lake is a little under 2 percent of the amount released annually by human fossil fuel burning. Therefore the process of releasing it could potentially have costs beyond building and operating the system.
Methane extraction
Methane extraction platform.
Lake Kivu has recently been found to contain approximately 55 billion cubic metres (1.94 trillion cubic feet) of dissolved biogas at a depth of 300 metres (1,000 ft). Until 2004, extraction of the gas was done on a small scale, with the extracted gas being used to run boilers at a brewery, the Bralirwa brewery in Gisenyi.[9][10] As far as large-scale exploitation of this resource is concerned, the Rwandan government has negotiated with a number of parties to produce methane from the lake.
In 2011 ContourGlobal, a U.S. based energy company focused on emerging markets, secured project financing to initiate a large-scale methane extraction project. The project will be run through a local Rwandan entity called KivuWatt, using an offshore barge platform to extract, separate, and clean the gasses obtained from the lake bed before pumping purified methane via an underwater pipeline to on-shore gas engines. Stage one of the project aims to build and supply three "gensets" along the lake shore, totaling 25MW of electrical capacity. Initial project operations are scheduled to commence in 2012.[11] In addition to managing gas extraction, KivuWatt will also manage the electrical generation plants and on-sell the electrical power to the Rwandan government under the terms of a long-term Power Purchase Agreement (PPA). This allows KivuWatt to control a vertically integrated energy offering from point of extraction to point of sale into the local grid. Extraction is said to be cost-effective and relatively simple because once the gas-rich water is pumped up, the dissolved gases (primarily carbon dioxide, hydrogen sulphide and methane) begin to bubble out as the water pressure gets lower. This project is expected to increase Rwanda's energy generation capability by as much as 20 times, and will enable Rwanda to sell electricity to neighboring African countries.[10] The firm was awarded the 2011 Africa Power deal of the year for innovation in the financing arrangements it obtained from various sources for the KivuWatt project.

A problem associated with the prevalence of methane is that of mazuku.
Biology and fisheries

Reflection of the sky on Lake Kivu
The fish fauna in Lake Kivu is relatively poor with 28 species, including four introduced species.[14] The natives are the Lake Rukwa minnow (Raiamas moorii), four species of Barbus (B. altianalis, B. apleurogramma, B. kerstenii and B. pellegrini), an Amphilius catfish, two Clarias catfish (C. liocephalus and C. gariepinus), Nile tilapia (Oreochromis niloticus) and 15 endemic Haplochromis cichlids.[14] The introduced species are three cichlids, the longfin tilapia (Oreochromis macrochir), O. leucostictus and redbreast tilapia (Coptodon rendalli), and a clupeid, the Lake Tanganyika sardine, Limnothrissa miodon.[14]
The exploitable stock of the Lake Tanganyika sardine was estimated at 2000–4000 tons per year.[15] It was introduced to Lake Kivu in the late 1959 by a Belgian Engineer A. Collart. At present, Lake Kivu is the sole natural lake in which L. miodon, a sardine originally restricted to Lake Tanganyika, has been introduced initially to fill an empty niche. Prior to the introduction, no planktivorous fish was present in the pelagic waters of Lake Kivu. In the early 1990s, the number of fishers on the lake was 6,563, of which 3,027 were associated with the pelagic fishery and 3,536 with the traditional fishery. Widespread armed conflict in the surrounding region from the mid-1990s resulted in a decline in the fisheries harvest.[16]
Following this introduction, the sardine has gained substantial economic and nutritional importance for the lakeside human population but from an ecosystem standpoint, the introduction of planktivorous fish may result in important modifications of plankton community structure. Recent observations showed the disappearance during the last decades of a large grazer, Daphnia curvirostris, and the dominance of mesozooplankton community by three species of cyclopoid copepod: Thermocyclops consimilis, Mesocyclops aequatorialis and Tropocyclops confinis.[17][18]
The first comprehensive phytoplankton survey was released in 2006.[19] With an annual average chlorophyll a in the mixed layer of 2.2 mg m-3 and low nutrient levels in the euphotic zone, the lake is clearly oligotrophic. Diatoms are the dominant group in the lake, particularly during the dry season episodes of deep mixing. During the rainy season, the stratified water column, with high light and lower nutrient availability, favour dominance of cyanobacteria with high numbers of phototrophic picoplankton.[19][20][21][22] The actual primary production is 0.71 g C m-2 d-1 (~ 260 g C m-2 y-1).[23]
A study of evolutionary genetics showed that the cichlids from lakes in northern Virunga (e.g., Edward, George, Victoria) would have evolved in a "proto-lake Kivu", much older than the intense volcanic activity (20,000-25,000 years ago) which cut the connection.[24] The elevation of the mountains west of the lake (which is currently the Kahuzi-Biega National Park, one of the largest reserves of eastern lowland (or Grauer's) gorillas in the world), combined with the elevation of the eastern rift (located in eastern Rwanda) would be responsible for drainage of water from central Rwanda in the actual Lake Kivu. This concept of "proto-lake Kivu" was challenged by lack of consistent geological evidence,[25] although the cichlid's molecular clock suggests the existence of a lake much older than the commonly cited 15,000 years.
Lake Kivu is the home of four species of freshwater crab, including two non-endemics (Potamonautes lirrangensis and P. mutandensis) and two endemics (P. bourgaultae and P. idjwiensis).[26] Among Rift Valley lakes, Lake Tanganyika is the only other with endemic freshwater crabs.[26]

San Francisco, 2013
It was December, a really cold day. Windy. Me and my girlfriend were talking and smoking a cigarette on a bench. We talked for at least 30 minutes. This guy was there, the entire time, with his feet in the chilly water and looking toward Alcatraz. After some time I was looking at him, intensely still, I tried to think about what was he looking for, where was he looking for, or who he was looking for .... in that direction ....
I taught the flower tower at the recent Origami Bogotá 2014 convention. Purposedly I didn't explain that you can do alternating twists (the most common version) and same direction twists. The talented Juan David Bernal folded the same side twists and then put the model in its tower state, which gave it a nice depth effect I had not seen before, so I had to try it.
