The absorption of light and colour in search of tone and texture is the pursuit of photography where painting with light often leads us into darkness. These pictures were created as I tested a new camera. When I first got my Canon 550D I thought that it was so light and well fitting in the hand that I could capture any lighting conditions. True there are some leaps and bounds for technology yet to perform to allow my unsteady hands to capture the lowest light conditions in sparkling clarity. I am sure that some of these technological leaps and bounds are occurring even as I type. It makes my hands tremble with anticipation to think of testing the next stable releases of stabilizing cameras with even lower light sensitive sensors.
Copper is found in all body tissues, plays a role in making red blood cells with iron & maintaining nerve cells, the immune system, formation of collagen, plays a role in energy production, aids in iron absorption, helps carry oxygen to your brain. Most copper in the body is found in the liver, brain, heart, kidneys, skeletal muscle & regulating stress response.
Body needs copper to produce specific enzymes responsible for making the connective tissue in our ligaments, tendons & heart. These enzymes are also involved with maintaining strong blood vessel structure & support bone formation. Copper plays an important role in melanin formation. Copper peptides possibly stimulates hair follicles, so they receive adequate oxygen & nutrients to produce new hair growth.
Normal copper level in blood is 70-140 microgram/dL for males & 80-155 microgram/dL.
Copper deficiency can lead to problems with connective tissue, muscle weakness, anemia, low white blood cell count, neurological problems, paleness. As an antioxidant, it binds with free radicals in our body, preventing them from harming our cells. Excessive free radicals, in long run, can cause chronic diseases like diabetes, arthritis & heart disease.
Besides, copper deficiency causes low body temperature, bone fractures and osteoporosis, low white blood cell count, irregular heartbeat, loss of pigment from the skin, thyroid problems.
Copper poisoning occurs from prolonged use of copper dietary supplements or from drinking contaminated water. Poisoning cause feeling of anxiety, irritability, non-attention, overexcited, sad, mood changes with other common symptoms abdominal cramps, nausea, jaundice etc.
Main reason for copper deficiency is malabsorption due to bariatric surgery. Ascorbic acid is known to inhibit the absorption of copper. Rich dietary copper sources include shellfish, seeds, nuts, organ meats, wheat-bran cereals, whole-grain products, chocolate, potatoes. Sweet potatoes are rich in beta carotene (vitamin A), copper, potassium, manganese, Vit B6, B5, Vit E.
Copper supplements like copper gluconate, copper sulfate, copper chloride are prescribed for copper deficiency as medication.
TAILPIECE: Copper is a micro-nutrient, eating or drinking out of copper vessels healthy as it is great for the immune system, digestion. Water stored in a copper vessel is alkaline and better for your health. However, avoid preparation of acidic foods in copper vessels since the acids react with copper.

Main Street, Gloucester - 1917
John Sloan (American, 1871 - 1951)
Sloan spent each summer from 1914 to 1918 in the small Cape Ann, Massachusetts, town of Gloucester. This work, executed during the fourth summer, reveals an aesthetic sophistication stimulated by the artist's absorption of the 1913 Armory Show's provocative presentation of avant-garde and modernist art. That landmark exhibition, coupled with those he helped to organize for The Eight in 1908 and the Exhibition of Independent Artists in 1910, inspired Sloan to explore a constellation of new ideas and methods. The body of work he created during the Gloucester years speaks of a renewed rigor as well as an intrepid and vigorous spirit of experimentation that would endure throughout his career.(1)
Initially, “Main Street, Gloucester” captivates as one of Sloan's distinctive "city-life" pictures, for which he garnered an enormous reputation. In the decade and a half preceding this painting's creation, his keen powers of observation, selection, and rendering were honed through his work as an illustrator, etcher, and painter of the urban scene. Yet his production during the Gloucester period represented a fundamental shift in his methods of conception and execution.
I had been dependent on waiting for the inspiration to paint a picture because I had so little leisure time to work for myself. So I decided to save up enough money to take off for a few months, go to the country and work from nature to get fresh ideas about plastic design and color rhythms.(2)
Thus issues of pure painting, rather than subject, motivated his work at this time.
This redirection toward plasticity, design, and color resulted from Sloan's thoughtful analysis of the work of what he called the "ultra-moderns" at the Armory Show. Sloan recalled the impact of that landmark exhibition: "It was exciting, it pointed many ways to freedom of expression, color, texture, most of all “graphics”. It pointed the way back to mental rather than visual thinking."(3) He credited the works of Cézanne, Matisse, and Van Gogh, among others, as powerful antidotes for the disease of "clever eyesight painting," the scourge of art production and consumption since the advent of photography.(4) He wrote: "Many intelligent people have accepted the false idea that accuracy in representing visual facts is a sign of progress in art. Such imitation of superficial effects has nothing to do with art, which is and always has been the making of mental concepts."(5)
Sloan's summers in Gloucester precipitated the auspicious convergence of several paths of inquiry in his own work. Using color as a constructive, expressive element in painting had been one of his preoccupations since 1909, when Robert Henri introduced him to Hardesty Maratta's experimental color system. Through it, Sloan had moved away from a dark tonal palette by increasing the presence of bright vivid colors. Maratta's system was predicated on the analogous relationship of the twelve colors in the chromatic wheel to notes in an octave of music.(6) The careful, precise orchestration of notes, chords, and harmonies was facilitated through the use of a set palette of premixed colors. With this palette, Sloan was confident that he could maintain the continuity of a painting's colors as he worked on it over time:
These Maratta colors opened up the palette for me. I had been analyzing the color of the city streets and the few things I painted from the model, in terms of color changes away from a basic raw umber note. With the Maratta colors I had six, twelve color-hues to work with, and from there could think of branching up into notes of higher intensity.(7)
His use of the Maratta system was given fresh impetus when he coupled it with plein-air techniques. The genre of landscape provided a comfortable arena in which to experiment with color that was often somewhat antinaturalistic. "After selecting the subject I would take half an hour to set my palette. Then I would pick up those set tones and draw with paint. Instead of imitating the colors in nature, I decided on some quality of color that interested me and set a limited palette."(8) His deep sympathy for humanity prevented his taking too many liberties with human subjects. "There is no better subject [than landscape] to free one of color habits. The variety in nature offers new color combinations, new ideas. You also feel more free to take liberties with color in nature than when painting from the figure."(9)
In “Main Street, Gloucester” Sloan effectively merged plein-air techniques with his exploration of color rhythms and plastic design. Through the skilled massing and organization of form, volume, and color, he devised a composition that is at once stable and balanced yet highly animated. By the artist's criteria for a successful composition, “Main Street, Gloucester” is a successful work. "A good design has stability. It is at rest with itself. Sense the opposition of horizontal and vertical rhythms to the dynamic movement of diagonal curves. Feel the weight of tones and colors, balance and counterbalance them against line and mass."
Born in Lock Haven, Pennsylvania, John Sloan was the first child and only surviving son of Henrietta Ireland, a former school teacher, and James Dixon Sloan, who repaired bicycles and worked as a photographer after the decline of his family's cabinetry business. Sloan's childhood was spent reading, sketching, and pouring over illustrated books. He attended Philadelphia's prestigious collegiate Central High School with fellow students William Glackens and Albert Barnes. In 1888 Sloan left school just six months shy of graduation, to become the family's primary breadwinner.
Sloan took a job as a cashier at Porter and Coates' bookstore and continued his education by reading and studying prints. He taught himself to etch using Philip Hamerton's “Etcher's Handbook” (1881), a popular "how-to" manual, and supplemented his income by selling prints at the bookshop. When A. Edward Newton, one of his co-workers, left to open his own store, he hired Sloan to etch giftbooks and pamphlets. At this time, Sloan made his first oil painting, “Self-Portrait” (1890; Delaware Art Museum, Wilmington), using another "how-to" book, John Collier's “Manual of Oil Painting” (1886), and painting on a piece of window shade his father gave him.
During the 1890s Sloan worked as an illustrator for the “Philadelphia Inquirer” and the “Philadelphia Press”, honing his skills as an astute "spectator of life." Fellow illustrators Glackens, George Luks, and Everett Shinn introduced him to a circle of artists, including Robert Henri, who soon became his close friend and mentor. Their shared aspirations to infuse American art with vitality and release it from the tyranny of the conservative academic system of juried exhibitions and prizes led them to form the group known as The Eight. Their landmark exhibition of 1908 established Sloan's career as an artist, exhibition organizer, and forward-thinking modernist.
Sloan's earliest paintings, many executed in a limited palette, are indebted to the figurative traditions of James McNeill Whistler, Thomas Eakins, and Thomas P. Anshutz. Sloan moved to New York in 1904 and took up the city-life subjects that distinguished his ensuing career. His spirit of artistic exploration, fed by the 1913 Armory Show and summer sojourns to the art colonies of Gloucester (1914-18) and Santa Fe (1919-50), led him to experiment with color, glazing, and a graphic painting technique that he called "linework."
From 1900 until his death, Sloan's paintings, etchings, and drawings were exhibited in nearly nine hundred exhibitions, including those at the Pennsylvania Academy of the Fine Arts, Carnegie Institute, Art Institute of Chicago, Corcoran Gallery of Art, Whitney Studio Club and C. W. Kraushaar Art Galleries. “The Gist of Art” (1939), written with his student Helen Farr (later, Mrs. John Sloan), stands as a thoughtful and eminently readable compendium of his ideas and practices. Happily, Sloan's numerous contributions to the arts and to art education were recognized and celebrated in the decade before his death.

The NBMAA collection represents the major artists and movements of American art. Today it numbers about 8,274 paintings, works on paper, sculptures, and photographs, including the Sanford B.D. Low Illustration Collection, which features important works by illustrators such as Norman Rockwell, Howard Pyle, and Maxfield Parrish.
Among collection highlights are colonial and federal portraits, with examples by John Smibert, John Trumbull, John Singleton Copley, Gilbert Stuart, and the Peale family. The Hudson River School features landscapes by Thomas Cole, Asher B. Durand, Martin Johnson Heade, John Kensett, Albert Bierstadt, and Frederic Church. Still life painters range from Raphaelle Peale, Severin Roesen, William Harnett, John Peto, John Haberle, and John La Farge. American genre painting is represented by John Quidor, William Sidney Mount, and Lilly Martin Spencer. Post-Civil War examples include works by Winslow Homer, Thomas Eakins, John Singer Sargent, George de Forest Brush, and William Paxton, and 19 plasters and bronzes by Solon Borglum. American Impressionists include Mary Cassatt, Theodore Robinson, John Henry Twachtman, J. Alden Weir, Willard Metcalf, and Childe Hassam, the last represented by eleven oils. Later Impressionist paintings include those by Ernest Lawson, Frederck Frieseke, Louis Ritman, Robert Miller, and Maurice Prendergast.
Other strengths of the twentieth-century collection include: sixty works by members of the Ash Can School; significant representation by early modernists such as Alfred Maurer, Marsden Hartley, John Marin, Georgia O’Keeffe, and Max Weber; important examples by the Precisionists Charles Demuth, Charles Sheeler, Preston Dickinson, and Ralston Crawford; a broad spectrum of work by the Social Realists Ben Shahn, Romare Bearden, Jacob Lawrence, and Jack Levine; and ambitious examples of Regionalist painting by Grant Wood, John Steuart Curry, and Thomas Hart Benton, notably the latter’s celebrated five-panel mural, The Arts of Life in America (1932).
Works by the American Abstract Artist group (Stuart Davis, Ilya Bolotowsky, Esphyr Slobodkina, Balcomb Greene, and Milton Avery) give twentieth-century abstraction its place in the collection, as do later examples of Surrealism by artists Kay Sage and George Tooker; Abstract Expressionism (Lee Krasner, Giorgio Cavallon, Morris Graves, Robert Motherwell, Sam Francis, Cleve Gray), Pop and Op art (Andy Warhol, Larry Rivers, Robert Indiana, Tom Wesselman, Jim Dine), Conceptual (Christo, Sol LeWitt), and Photo-Realism (Robert Cottingham). Examples of twentieth-century sculpture include Harriet Frishmuth, Paul Manship, Isamu Noguchi, George Segal, and Stephen DeStaebler. We continue to acquire contemporary works by notable artists, in order to best represent the dynamic and evolving narrative of American art.

My photowalk of August 11, 2023. in the district of La Croix Rousse, Lyon, France, with my Zorki-4K camera circa 1977.
I equipped the Zorki-4K with the Jupiter-12 1:2.8 f=3.5cm and tried for the first time the use of a FOCA DYMA 42mm push-on filter. In turn, this induced a noticeable vignetting that I corrected to my best during the digital processing. Then, this combinaison is not to recommend.
The camera was loaded with an Fomapan Classic 100 36-exposure film. It was exposed for 32 ISO instead of 100 ISO to compensate the DYMA filter absorption (coefficient x3.5); I used my Autometer III Minolta light meter fitted with a 10° finder for selective measurements privileging the shadow areas.

After completion, the film was processed using Adox Adonal (Agfa Rodinal) developper at dilution 1+50 and 20°C for 9min. 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.
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 Vivio Y76 color pictures.
About the camera :
This Zorki-4K camera was manufactured in 1977 by KMZ company ( Красногорский механический завод, Krasnogorskiy Mechanicheskiy Zavod) located in the Moscow region. KMZ also manufactured the ZENIT SLR's among many other productions. Zorki 4K was produced between 1972 to 1978 and the previous Zorki models were inspired by the Leica II since 1949. This model 'Made in USSR" is branded in roman characters, intentionally for exportation. Other Zorki 4K were also branded in Cyrillic as "Зоркий". Zorki 4K was sold basically either with this Jupiter-8 lens 1:2 f=50mm or the Industar lens1:3.5 f=50mm. The Jupiter-8 is a Sonnar Zeiss optical formula and fits to the Zorki body using the screwing 39mm Leica mount.
The camera was sold to me in August 2022 with its original ever-ready leather bag, a front lens cap and a small shade hood accessory Minolta D42KA. The shade hood and filter of my Focaflex also fit to the Jupiter lens (Leica standard 42 mm filter)
About the Jupiter-12 lens : The Jupiter-12 is a copy of the pre-war Carl Zeiss Biogon 3.5cm f/2.8 for the Contax that Russia produced since 1948 to around 1980. Biogon is of course a non-retro focus lens that penetrate deeply in the camera body with a protruding last glass element that should be protected with the special rear lens cap that came with. The lens was manufactured in 1975 by the KMZ sister company LZOS company (Lytkarinski Zavod Opticheskogo Strekla) in Lytkarino (Moscow region).

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.

Reconstruction of the marble funerary stele of Phrasikleia, 2010
Polymethyl metacrylate
Vinzenz Brinkmann & Ulrike Koch-Brinkmann
The colors in this reconstruction of an ancient Greek marble statue of a young woman were identified on the original with the help of ultraviolet-visible absorption spectroscopy and X-ray fluorescence spectroscopy. These techniques revealed numerous pigments: red and brown madder lake, red and brown ocher, and lead white for the eyes, skin, and hair, as well as red and yellow iron oxide, orpiment, and cinnabar for the dress. Certain ornaments had been gilded or perhaps covered with a lead-and-tin foil.
"This richly decorated statue stood on the tomb of a girl named Phrasikleia. She wears a crown of lotus buds and holds a single bud in her left hand. The epigram on the base tells us that she died young, before she could marry.
The famous sculptor Aristion of Paros signed the work. With the help of ultraviolet-visible absorption spectroscopy (UV-Vis spectroscopy) and X-ray fluorescence spectroscopy (XRF), traces of a numbers of colors on the flesh and clothing could be identified: red and brown madder, red and brown ocher, lead white for the eyes, flesh, and hair, as well as three different reds and yellows (red and yellow iron oxide and orpiment for the garment). Wherever the underside of the fabric is visible - on the sleeve and the lower hem - a dark red pigment (hematite) was deliberately used. Gold leaf and lead tin foil that gleams like silver were applied to the dress and the jewelry. Metal rosettes and shiny yellow swastikas (painted with orpiment and gold ocher) were scattered over the entire garment. Additionally, stars appear on the back of the garment, evidently intended to represent a constellation.
The reconstruction made in 2010 follows the incised patterns and colors that were identified by scientific analysis. But after the latest discoveries by the conservators in the Athens National Museum, the red ocher of the robe has been mixed with cinnabar, giving the color an even more intense effect. The polish of the skin was based on contemporary Egyptian mummy portraits and was done using agate, while a shimmering lacquer (gum arabic) was applied to the irises of the eyes. In 2019, gilding was added to the volute ornament of the belt and precious stones were inserted into the round depressions that are still preserved."
Pigments used in the reconstruction: red: burnt Cypriot yellow ocher, cinnabar, red ocher, hematite; yellow: light yellow Cypriot ocher, gold ocher, orpiment; white: lead white; brown: brown madder, umbra; black: vine black; flesh color: red and yellow ocher, lead white (polished).*

Chroma: Ancient Sculpture in Color
(July 2022 to March 2023)
Ancient Greek and Roman sculpture was once colorful, vibrantly painted and richly adorned with detailed ornamentation. Chroma: Ancient Sculpture in Color reveals the colorful backstory of polychromy—meaning “many colors,” in Greek—and presents new discoveries of surviving ancient color on artworks in The Met’s world-class collection. Exploring the practices and materials used in ancient polychromy, the exhibition highlights cutting-edge scientific methods used to identify ancient color and examines how color helped convey meaning in antiquity, and how ancient polychromy has been viewed and understood in later periods.
The exhibition features a series of reconstructions of ancient sculptures in color by Prof. Dr. V. Brinkmann, Head of the Department of Antiquity at the Liebieghaus Skulpturensammlung, and Dr. U. Koch-Brinkmann, and introduces a new reconstruction of The Met’s Archaic-period Sphinx finial, completed by The Liebieghaus team in collaboration with The Met.Presented alongside original Greek and Roman works representing similar subjects, the reconstructions are the result of a wide array of analytical techniques, including 3D imaging and rigorous art historical research. Polychromy is a significant area of study for The Met, and the Museum has a long history of investigating, preserving, and presenting manifestations of original color on ancient statuary.

In the Met
The Metropolitan Museum of Art was conceived in Paris by John Jay in Paris, 1866, as a "national institution and gallery of art" for the American people. The Union League Club in New York campaigned for funding, and The Metropolitan Museum of Art opened to the public in 1870, in the Dodworth Building 681 Fifth Avenue. Initially formed from donations by its founders, the Museum collection increased to the point that it outgrew the initial site, and then a consecutive one, moving to its current location (on Fifth Avenue and 82nd Street) in 1880.
The initial museum building was designed by Calvert Vaux and Jacob Wrey Mould, with extensions added from 1888 onwards - the Fifth Avenue facade, Grand Stairway, and Great Hall, designed by Richard Morris Hunt, opened 1902, and the Fifth Avenue wings by McKim, Mead & White in 1910. The last major development was the installation of glass at the sides and rear of the building, designed by Roch-Dinkeloo in 2011-12.

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.

After completion, the film was rewound and processed using 350 mL of Adox Adonal (Agfa Rodinal) developer prepared at the dilution 1+25 for 12min15 at 20°C.
Digitizing was made using a Sony A7 camera (ILCE-7, 24MP) fitted to a Minolta Auto Bellows III with the Minolta slide duplication accessory and Minolta Macro Bellow lens 1:3.5 f=50mm. The diffuse light source was a LED panel CineStill Cine-lite.
The RAW files obtained were inverted within the latest version available of Adobe Lightroom Classic (version 14.2) and edited to the final jpeg pictures without intermediate file. They are presented either as printer files with a frame or the full size JPEG's together with some documentary smartphone color pictures.
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.
With a water absorption rate of less than 0.5 percent, this Koydol collection is ideal for any wet surface application, including floors, walls, and countertops. The series offers several different textures and sizes in neutral and earthy colors.
