Sonata Vario suspended sound absorption panels installed within the restaurant at Llanerch Vineyard to reduce noise and reverberation during service
The Access technology addresses the problem of poor intestinal absorption by utilizing the body's natural transport system. Cobalamin™ (a vitamin B12 or COBALAMIN analog) is actively transported from the gut to the blood stream by a receptor-mediated process the body normally uses for transport of vitamins.
The absorption bands near 400 and 600nm are associated with an F-centre in the presence of Y3+ ions. The dip between 1900 and 2000nm could be water. The broad band(s) between 1200 and 1600 is/are ???
There is some Eu2+ fluorescence emission around 400nm in the bottom of the F-centre band.

On July 4, 2024, I took my camera Zenza Bronica S2A (Japan, 1972-1977) for a tour in the district of Fourvière, Lyon, France.
The Nikkor normal lens 1:2.8 f=75mm was equipped of a Hoya Yellow (K2) 67mm screwed filter and the dedicated Zenza Bronica metal hood.
I used an Ilford FP4+12-exposure negative 120-format film . The film was exposed for 64 ISO (to compensate the filter absorption) using an Autometer III Minolta lightmeter fitted with a 10° finder for selective measurements privileging the shadow areas.

Funeral mask, Roman period. The original is exposed at the Gallo-Roman Museum next to this place.
After the view #12 exposed, the film was fully rolled to the taking spool and was developed in a Paterson tank with a spiral adapted to the 70mm large film. 500 mL of Adox Adonal (Agfa Rodinal) developer were prepared at the dilution 1+25 and the film processed for 9min at 20°C.
Digitizing was made using a Sony A7 camera (ILCE-7, 24MP) held on a Minolta vertical macro stative device and adapted to a Minolta MD Macro lens 1:3.5 f=50mm. The light source was a LED panel (approx. 4x5') CineStill Cine-lite fitted with film holder "Lobster" to maintain flat the 70mm films.
The RAW files obtained were inverted within LR and edited to the final jpeg pictures without intermediate file. They are presented either as printed files with frame or the full size JPEG.
All views of the film are presented in the dedicated album either in the printed framed versions and unframed full-size jpeg accompanied by some documentary smartphone Vivo Y76 color pictures.
Strangely, although its 1.8 kg the camera is not at all uncomfortable to carry, especially when the camera is hold on the chest by the neck strap. I did not feel tied after this photo tour (about 4km walking). It is easily to get a good stability and a precise framing with the camera on the chest.
Details about the camera :
The Zenza Bronica’s S (ゼンザブロニカ) were often referred to the « Japanese Hasselblad ». Conceived in the year 50’s (Bronica D, 1959) was manufactured in ToKy,o Itabashi-ku, Minami-Tokiwadai with the Japan engineering spirit of that time : « we wlll do as … in better! »; The Bronica (ETR, SQ series) camera’s were progressively discontinued twenty years ago between 2002 and 20O4 and the brand was bought by Tamron company and disappeared from the market.
The Zenza Bronica S2A was produced by Bronica Insdutries founded by Yoshino Zenzaburo, between 1972 and 1977 and was the ultimate model of fully mechanical medium format modular SLR o th e S series. The camera in made in stainless steel 18-8 quality for the outer elements. The S2A is still a focal-plane shutter camera with automatic diaphragm and automatic film back coupled to the shutter cocking through a re-arming crank. Bronica were equipped either with Nikon Nikkor lenses, Zenzanon of Komura optics.
I got this exemplary from a French eBay auction for a quite reasonable price, equipped with a Nikkor-P normal lens 1:2.8 f=75mm, a generic 67mm lens cap, and a neck/shoulder Bronica strap. I found at my monthly trade -exchange photo meeting new-old stock 67mm filters (Hoya HMC anti-UV, Yellow K2, and a Zenzza Bronica Skylight 1A) and two shade shade hoods (one generic foldable and a rigid metal Zenza Bronica Japan). I also found a nice storage box 15x20x20cm to store the machine with silica-gel protectant.
The camera fit in my ThinkTank Retrospective 5 usual bag as easy as my French TLR Semflex. The weight is however twice more heavy by about 1.8 kg (0.8 kg for my Semflex TLR).

My photo walk of July 4, 2023 in the district of "La Croix Rousse", Lyon, France.
For the photo session, I equipped my Foca PF2B, a 35mm French range-finder camera year 1948, with my new and optically clean normal lens Oplar 1:3.5 f=5cm lens recently sourced from a trusted specialist of FOCA camera's and lenses. This lens, with the serial number beginning by 032, was manufactured in 1947 by the Optique & Précision de Levallois (OPL) French company, most likely in its factory of Châteaudun, Eure, France. The lens was also equipped withe with a Foca filter "Dyma". x3.5 for all the views and a metal shade-hood.
Due to a rather "foggy" finder, I used the Foca multi-focal external finder for the 50mm lense. The focus is almost impossible to evaluate using the internal range-finder that is, however, well operating. When necessary (distances bellow ca 5-6m), exact distances were measured using a LASER meter and reporting the value found to the lens distance scale.
The Foca camera was loaded with an Ilford XP2 Super 36-exposure film. It was exposed for 125 ISO to compensate the Dyma filter absorption, using an Autometer III Minolta lightmeter fitted with a 10° finder for selective measurements privileging the shadow areas.
The Ilford XP2 Super film is a monochromatic chromogenic film with a very high acutance and a very wide exposure latitude for regular C-41 process.

After exposure, the film was developped by a local lab service using the C-41 protocol. The film was then digitalized using a Sony A7 body fitted to a Minolta Slide Duplicator installed on a Minolta Auto Bellows III with a lens Minolta Bellow Macro Rokkor 50mm f/3.5. The RAW files obtained were processed without intermediate files in LR and edited to the final jpeg pictures.

About the camera :
This Foca PF2B is an early series (circa 1948) of the Foca PF2B 35mm range-finder camera released in 1945. The PF2B model of Foca has the 36mm screw mount of other Foca PF (PF standing for "Petit Format"). Foca camera's were constructed in France by the company "Optique & Precision de Levallois" (OPL) in the OPL factory of Chateaudun (Eure) starting from 1946. This factory still exists under the name of SAFRAN a French company producing aerospace devices and systems.
About the DYMA filter :
To my knowledge this type of filter was exclusively produced in France by Foca. The filter is called "DYMA" due to the presence of neodymium in the glass giving an unusual absorption by bands in the visible spectrum. In particulier blue and yellow color ans more absorbed than the rest of the spectrum. The filter existed in two different versions with the coefficient x2.5 or 3.5.
Wetlands are biodiversity rich sensitive ecosystems that harbor hundreds of plants, insects, birds and other animals uniquely adapted to their wetland mode of life.They are crucial to maintain the regional water balance through ground water recharge and absorption of flood waters and also serve as the rice bowl of developing countries. Nevertheless, wetlands play immense role in the socio-economic and livelihood aspects of local communities living around the wetland. In India, rural communities depend wetland for livelihood through farming, mat making etc; for food through fishing and hunting; for roof thatching by collection of reeds and palm leaf ; for firewood; for fodder etc. However, these wetlands are now under a threat of conversion for big industrial and real estate projects, change in lifestyle of local community, over extraction of resources by increased population, pollution,waste dumping, eutrophication and pesticide farming. There are three important wetlands in the Puducherry region namely Oussudu, Bahour and Kaliveli that provide important resources for local communities and also are a home to tens of thousands of migratory birds that visit the Puducherry region in winter. These wetlands have been acknowledged as Important Bird Areas(IBAs) by IBCN, since many of these birds are represented in more than 1% of their global population.
The recent threat on wetlands of Puducherry is more due to the change in life style of local community living around these wetlands. The younger generation is not much dependent on wetland resources, The younger and modern generation has lost the compassion and bonding to the wetland which their forefathers maintained through sustainable livelihood practices. This has resulted in a change in attitude and perception of the community towards unsustainable farming and resource extraction, game hunting, intensive fishing and reclamation, ultimately resulting in shrinking of wetland area and loss of biodiversity at an alarming pace. Local community is leaving the traditional farming practices for more fertilizer and pesticide based farming; fish stock is depleted using invasive Gill nets. Since Puducherry is fast developing region with rapidly growing commercial tourism and industrial establishments, these wetlands are under the threat of reclamation for resort construction and other commercial establishments. Poaching for a sport as well as open selling of birds including the threatened species is common. School drop-out are noticed to get attracted to such practices to make easy money as well as hunting for a sport with peers. With time, they may grow into expert hunters who will depend on poaching as the main source of income for the family. There are many wetland awareness programs organized by Forest Department as well as NGOs targeting school kids and educated community through workshops. School drop-outs are often not specially targeted by any of such programs and often not brought under the ambit of such programs. This gap needs to be addressed for local conservation efforts to be fully effective. We have chosen birds as the umbrella species whose conservation will in turn protect the lake and biodiversity as a whole. Birds are attractive and beautiful; ,which may easily get compassion from drop-out kids if guided appropriately. With proper efforts, the poachers can be turned to protectors and expert tour guides to facilitate ecotourism.

For the test film of the Jupiter-9 lens I mounted it on the Leningrad camera (see below for detail about the lens and the camera). The lens was fitted with a generic yellow filter (screw-on 49mm) and a generic cylindrical metal shade hood designed for a 50mm lens. By safety, a lens cap fitted on the hood (55mm) was also used to protect the shutter curtains from an accidental sun burning (I forgot twice to remove the cap before shooting...)
I loaded the Leningrad with a Rollei RPX 400 film exposed for 250 ISO to compensate the absorption of the yellow filter. The light metering was done using a Minolta Autometer III with the 10° viewer for selective metering privileging the shadows areas.
The viewer of the Leningrad has build-in frame for the 85mm and is fully compensated for the parallax error.

About the camera :
After several months, my local repair shop gave up to repair my first exemplary of Leningrad camera. I got that GOMZ Leningrad for less than the price of the lens (50€) a year ago (February 24, 2024, flic.kr/s/aHBqjBftyP) at the monthly collector meeting in Saint-Bonnet-de-Mure, near Lyon, France. I looked then again for a working one.
Leningrad’s are fascinating Russian range-finder 35mm camera’s produced in Leningrad (USSR) / Saint-Petersburg, from 1956 to 1968 at about 76.000 units. It is not really a rare camera but appears only from time-to-time in the classical collector’s networks.
The Leningrad camera project was developed by GOMZ company (ГОМЗ, Государственный оптико-механический завод, Ленинград = Gosularstvennyi Optiko-Mekhanicheskii Zavod =State Optical-Mechanical Factory), Leningrad, USSR. The Leningrad ’s were constructed to a very high degree of precision and likely the most advanced rangefinder ever made at that time in Russia. At the 1958 World Exposition in Brussels, the Leningrad was awarded the "Grand Prix de Bruxelles”. Modified Leningrads were also used in the Soviet space program. In addition to a complex parallax-compensated multi-focal (for 3.5, 5, 8.5 and 13.5cm) collimated system, the camera has a built-in spring-powered mechanical motor for an automated film advance after each view taken. The Leningrad mounts the 39mm Leica-type thread lenses, especially of the Jupiter series of lens derived of classical Carl Zeiss lenses designed for the Contax (Biogon 3.5cm and Sonnar’s 5, 8.5 and 13.5cm).
In 1965, GOMZ became LOMO ( ЛОМО, Ленинградское oптико-механическое oбъединение (Leningradskoïe Optiko-Mekhanitcheskoïe Obiedinienie) that is still existing, producing instrumental optical devices (www.lomo.ru).
On eBay, I focused on a LOMO Leningrad year 1965 in working condition but without the original film plate. I got the camera for 130€ including the leather bag and a standard lens Jupiter-8 1:2 f=5cm. The seller adapted cleanly a different film plate that looked to work, but my idea was to use the camera back of my faulty Leningrad. This film plate may a precision glass plate special designed for optimum film transport and optical planarity. I received my new Leningrad on January 31, 2025 in good condition.
After a very careful inspection and a detailled cleaning, I decided to make a test film using a FOMAPAN 200 black-and-white film. On the Leningrad it is said that there is absolutely no way to check the correct film advance during the shooting session. The rewind should not be up since the mechanical forces induced would be too high for the spring-powered spooling barrel. The film should be also in a quality not too tight film cartridge and should be checked before use. This stressful machine should be manipulated with maximum care when not familiar with it.
About the lens Jupiter-9:
New in my collection in Feb. 2025, this very popular lens Jupiter-9 1:2.8 f=85mm for my Zorki’s and Leningrad camera’s. The lens was produced in 1978 by the LZOS company (Лыткаринский завод Оптического Стекла , Lytkarino Zavod Optychisovo Sticklo) located in Lytkarino (about 100 km Noth to Moscow).
I sourced a clean exemplary in Germany at regular price given the popularity of the Jupiter-9 (170€) with the Leica 39mm thread mount, front and rear caps plus the lens black storage canister. The lens is popular especially among videographers due to its peculiar bokeh and perfectly round shaped diaphragm made of 15 blades.
Originally, the Jupiter 9 is based on the design of the Carl Zeiss Sonnar designed for the Zeiss Ikon Contax in the years 1930’s. Production began in USSR in 1948, when the lens was initially called the ЗК-85 (Sonnar Kransogorsk) and it was assembled using mostly German parts in Contax/Kiev mount. The lens was also adapted to Zorki (M39) mount to fit the Zorki cameras early in production It appears, for both Zorki and Kiev mount, in a 1949 catalogue. By 1951 the name changes to Jupiter 9 (Юпитер-9). The lens has seven glass elements in three groups; a single glass at the front, and two cemented groups of three. All versions of the lens are coated. It was made by the KMZ (Красногорский механический завод, Krasnogorski Mekhanicheskii Zavod) and LZOS factories, in Leica 39 mm thread mount for Fed and Zorki rangefinders, but originally it was a Contax bayonet used in Kiev cameras. Jupiter-9 lenses were also made at the Arsenal factory in Ukraine, for Kiev rangefinders,but initially released as KMZ. It was later adapted for M42-mount Zenit SLR cameras, with an M24×1 thread mount.
On the last day of our holiday I did the whale watch tour at Kaikoura on the east Coast of the South Island.
Just off the shore the very deep canyon Kaikoura Trench is a feeding zone for male sperm whales and they can be seen in these seas year round. It's an amazing trip I'd recommend to anyone.
Physeter macrocephalus
A marine mammal species, order Cetacea, a toothed whale (odontocete) having the largest brain of any animal. The name comes from the milky-white waxy substance, spermaceti, found in the animal's head. The sperm whale is the only living member of genus Physeter. A bull can grow to 20.5m long. It is the largest living toothed animal. The head can take up to one-third of the animal's length. It has a cosmopolitan distribution across the oceans. The species feeds on squid and fish, diving as deep as 3 kilometres which makes it the deepest diving mammal. Its diet includes giant squid and colossal squid. The sperm whale's clicking vocalization is the loudest sound produced by any animal, but its functions are uncertain. These whales live in groups called pods. Pods of females and their young live separately from older males. The females cooperate to protect and nurse their young. Females give birth every three to six years, and care for the calves for more than a decade. Over most of the period from the early 18th century until the late 20th century, the sperm whale was hunted to obtain spermaceti and other products, such as sperm oil and ambergris. Spermaceti found many important uses, such as candles, soap, cosmetics and machine oil. As a result of whaling, the sperm whale is currently listed as vulnerable by the IUCN. The sperm whale has few natural predators, since few are strong enough to successfully attack a healthy adult; orcas attack pods and kill calves. The sperm whale can live for more than 70 years.
The name sperm whale is an apocopation of spermaceti whale. Spermaceti is the semi-liquid, waxy substance found in the spermaceti organ or case in front of and above the skull bone and also in the junk, the area below the spermaceti organ and just above the upper jaw. The case consists of a soft white, waxy substance saturated with spermaceti oil. The junk is composed of cavities filled with the same wax and spermaceti oil and intervening connective tissue. The sperm whale is the largest toothed whale, with adult males measuring up to 20.5 metres (67 ft) long and weighing up to 57,000 kilograms. It is among the most sexually dimorphic of all cetaceans. At birth both sexes are about the same size, but mature males are typically 30% to 50% longer and three times as massive. The sperm whale's distinctive shape comes from its very large head, which is typically one-third of the animal's length. The blowhole is located very close to the front of the head and shifted to the whale's left. This gives rise to a distinctive bushy, forward-angled spray. The sperm whale's flukes are triangular and very thick. The whale lifts its flukes high out of the water as it begins a dive. It has a series of ridges on the back's caudal third instead of a dorsal fin. The largest ridge was called the 'hump' by whalers, and can be mistaken for a dorsal fin because of its shape. In contrast to the smooth skin of most large whales, its back skin is usually knobbly and has been likened to a prune by whale-watching enthusiasts. Skin is normally a uniform grey in color, though it may appear brown in sunlight. Albinos have also been reported. The sperm whale has 20 to 26 teeth on each side of its lower jaw. The teeth are cone-shaped and weigh up to 1 kilogram. The purpose of the teeth is unknown. Teeth do not appear to be necessary for capturing or eating squid, and well-fed animals have been found without teeth. One hypothesis is that the teeth are used in aggression between males. Bulls often show scars which seem to be caused by the teeth. Rudimentary teeth are also present in the upper jaw, but these rarely emerge into the mouth. Sperm whales, along with bottlenose whales and elephant seals, are the deepest-diving mammals believed to be able to reach 3 kilometres and remain submerged for 90 minutes. More typical dives are around 400 metres (1,300 ft) and 35 minutes in duration. The sperm whale has adapted to cope with drastic pressure changes when diving. The flexible ribcage allows lung collapse, reducing nitrogen intake, and metabolism can decrease to conserve oxygen. Myoglobin, which stores oxygen in muscle tissue, is much more abundant than in terrestrial animals. The blood has a high red blood cell density, which contain oxygen-carrying hemoglobin. The oxygenated blood can be directed towards the brain and other essential organs only when oxygen levels deplete. The spermaceti organ may also play a role by adjusting buoyancy. While sperm whales are well adapted to diving, repeated dives to great depths have long term effects. Bones show pitting that signals decompression sickness in humans. Older skeletons showed the most extensive pitting, whereas calves showed no damage. This damage may indicate that sperm whales are susceptible to decompression sickness, and sudden surfacing could be lethal to them. Between dives, the sperm whale surfaces to breathe for about eight minutes before diving again. Odontoceti (toothed whales) breathe air at the surface through a single, S-shaped blowhole. Sperm whales spout (breathe) 3–5 times per minute at rest, increasing to 6–7 times per minute after a dive. The blow is a noisy, single stream that rises up to 15 metres (49 ft) above the surface and points forward and left at a 45° angle. On average, females and juveniles blow every 12.5 seconds before dives, while large males blow every 17.5 seconds before dives. The brain is the largest known of any modern or extinct animal, weighing on average about 8 kilograms though the sperm whale has a lower encephalization quotient than many other whale and dolphin species, lower than that of non-human anthropoid apes and much lower than humans'. Like other toothed whales (suborder odontoceti), sperm whales use echolocation as one means to find food because their habitat has favorable acoustic characteristics and light absorption by water and suspended material limits visual range. The whale emits a focused wide angle beam of high-frequency clicks. Passing air generates sounds from the bony nares through the phonic lips (also known as "monkey lips"), a structure within the head. The skull, melon and various air sacs in the whale's head all play important roles in forming and focusing the beam of sound. The lower jaw is the primary echo reception path. A continuous fat-filled canal transmits received sounds to the inner ear. The spermaceti organs may help adjust the whale's buoyancy. Before diving, cold water enters the organ and it is likely that the blood vessels constrict, reducing blood flow and hence temperature. The wax therefore solidifies. The increase in specific density generates a down force of about 392 newtons (860 lb) and allows the whale to dive with less effort. During the hunt, oxygen consumption, together with blood vessel dilation, produces heat, and melts the spermaceti, increasing its buoyancy, enabling easy surfacing. The case may also aid echolocation. The organ's variable shape narrows or spreads the sound. The sperm whale has two nostrils. An external nostril forms the blow hole, and an internal nostril presses against the bag-like spermaceti container. The male's spermaceti organ is much larger than the female's. This may be a case of sexual selection, enabling males to compete for females using sound displays.
