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.

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.

Metal roofs are increasingly popular due to their durability, energy efficiency, and modern aesthetic. However, to maximize their lifespan and performance, applying a specialized coating can be a game-changer. Metal roof coatings offer a variety of benefits, including enhanced protection against the elements, improved energy efficiency, and increased resistance to corrosion and rust. These coatings create a barrier that can reflect harmful UV rays, reducing heat absorption and lowering energy costs. Additionally, they can help prevent water infiltration and prolong the roof's life by protecting it from wear and tear. Different types of coatings are available, and their specific advantages and essential considerations for maintaining a metal roof. Through this knowledge, homeowners can make informed decisions that enhance the appearance of their roofs and ensure long-lasting performance.
Metal Roofing Materials
Metal roofing materials are famous for their durability, energy efficiency, and aesthetic appeal. Beyond their inherent advantages, applying specialized coatings, such as silicone and acrylic, can enhance these benefits even further. Elastomeric roof coatings also play a vital role in protecting metal roof surfaces. These coatings serve as protective barriers, safeguarding metal roofs against environmental factors such as UV rays, moisture, and corrosion. Additionally, these coatings can improve the roof's energy efficiency by reflecting sunlight, creating an excellent roof effect that helps regulate indoor temperatures and reduce cooling costs, especially in commercial properties.
Various coatings are available for metal roofs, highlighting unique properties and benefits. For instance, some coatings offer excellent UV and corrosion resistance, making them ideal for extending roof life, especially under extreme temperatures. The choice of coating can also depend on the specific roof type and the property's needs, whether for residential or commercial roofs. Understanding these options is essential for homeowners and builders looking to optimize the performance and longevity of metal roofs in residential and commercial applications.
Importance of Coatings for Metal Roofs
Coatings for metal roofs are crucial in enhancing the longevity and performance of roofing systems. As metal roofs become increasingly popular due to their durability and energy efficiency, applying protective coatings can significantly amplify these benefits. These coatings serve multiple purposes, including safeguarding the roof from harsh environmental elements, reducing thermal expansion, and improving energy efficiency through reflective properties. By creating a barrier against moisture, UV rays, and corrosion, coatings help extend metal roofs' lifespan while minimizing maintenance costs. With a wide range of options, building owners can choose coatings that provide protection and add aesthetic appeal, ensuring that their roofs remain functional and visually attractive for years. Understanding the importance of coatings is essential for anyone looking to invest in the long-term performance of their metal roofing system.
Benefits of Coating Metal Roofs
Coating for metal roofs offers numerous benefits, making them an excellent investment for homeowners and businesses. These coatings significantly enhance weather resistance and provide UV protection, safeguarding metal surfaces from the damaging effects of sun exposure and harsh weather conditions. Due to their flexibility and durability, silicone and elastomeric roof coatings are popular. The choice of metal roof paint can depend on the type of metal roof and the specific roof substrate.
Proper application techniques and adhesion allow these coatings to last 15-20 years, providing long-lasting protection. They also contribute to energy efficiency by reflecting heat, potentially saving up to 30% on cooling costs. The flexibility of these coatings allows them to accommodate the natural expansion and contraction of the roof structure, minimizing the risk of cracks or other damage. Additionally, these coatings are lightweight, reducing the load on the roof deck and ensuring minimal structural impact.
An essential part of any roof coating project is a thorough roof inspection to assess the condition of the roof structure and prepare the metal surfaces. Environmentally friendly options are available, aligning with sustainability goals and reducing a building's carbon footprint.
Enhancing Energy Efficiency
Metal roof coatings significantly enhance energy efficiency by effectively reflecting UV rays and minimizing heat buildup, which lightens the workload on cooling systems. This reduction in energy consumption leads to lower utility bills for property owners and contributes to a greener environment by decreasing the overall energy demand. Reflective coatings promote sustainable roofing practices by eliminating the need for tear-offs and minimizing waste generation during upgrades or maintenance. By choosing metal roof coatings, homeowners can enjoy the benefits of improved energy efficiency and environmental stewardship, positively impacting their finances and the planet. Emphasizing the importance of these coatings underscores their role in promoting sustainable roofing while ensuring optimal performance and comfort in residential and commercial buildings.
Extending the Lifespan of Roofs
Roof coatings play a vital role in extending the lifespan of metal roofs by offering essential protection against various environmental factors, such as UV rays, moisture, and temperature fluctuations. High-quality coatings, such as elastomeric roof coating systems and urethane, are crucial for ensuring enhanced durability, as they form a robust layer of protection that minimizes wear over time. These coatings are particularly effective on seam metal roofs and roof panels, providing water and impact resistance.
In addition to their protective qualities, roof coatings also offer color retention and the option for custom colors, allowing property owners to maintain or enhance their roof's appearance. Regular maintenance and inspections, including checking for issues around roof penetrations, are paramount in preserving the effectiveness of these coatings. This routine care allows for the early detection of potential problems and ensures the protective layer remains intact.
By investing in superior roof coatings and committing to routine care, property owners can significantly improve the longevity of their type of roof. This approach also avoids traditional roof tear-off, making it a cost-effective choice for any roofing project. Consulting with a professional roofing contractor can provide valuable insights into selecting the appropriate coating based on the roof's physical properties and specific needs. This proactive approach safeguards the investment through reliable environmental protection and extends the roof's overall life.
Improving Aesthetic Appeal
Metal roofs are a durable and popular choice for many homeowners and commercial buildings, but their aesthetic appeal can sometimes be enhanced for a more visually pleasing appearance. By applying specialized coatings, homeowners can transform the look of their metal roofs, offering a range of colors, finishes, and textures to complement any architectural style. These coatings improve the visual aspect of metal roofs and provide superior color retention and heat reflectivity, reducing heat gain and enhancing energy efficiency.
Additionally, coatings with rust inhibitors help protect the roof against weather damage and rust, effectively slowing down the rate of rust formation. This protective layer is especially beneficial in areas prone to adverse weather and other environmental conditions, ensuring the roof remains visually appealing and structurally sound.
These coatings' application and curing processes are critical as they determine the effectiveness of the coating in providing protection and durability. Coating manufacturers often offer different warranty periods based on the product's performance, giving homeowners peace of mind. Whether opting for a white finish to maximize heat reflectivity or a custom color to match the home's exterior, the suitable coating can significantly elevate the overall curb appeal of a property, making it stand out in a neighborhood and potentially increasing its value.

Differential Method of Measurement of the Two-Photon Absorption Coefficient in Si-Photodetector Using an Electrically Focused Tunable Lens
Justin Deterding, Francisco Lagunas
Southern Illinois University Edwardsville
We report the measurement of the Two Photon absorption coefficient (TPA) of a silicon photodiode using the Differential F-Scan technique. The technique works by modulating the focal length of an electrically Focus Tunable Lens (EFTL). Using the EFTL allows for simplification of the experimental setup, an increased signal-to-noise ratio (SNR), and increased robustness of the setup. The TPA coefficient is measured using a 1.55 μm laser source, with 50 fs pulse duration operating at 23mW and 80 MHz repetition rate. The TPA coefficient of a silicon photodiode is reported and compared with other traditional measurements like z-scan, finding good experimental agreement.
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.

A view from the dark side….
Dark nebulae or absorption nebulae are types of interstellar clouds, also called molecular clouds, that are so dense that they obscure the visible wavelengths of light from objects behind it, such as background stars and emission or reflection nebulae.
The astronomer Edward Barnard compiled a list of these dark makings in the sky, known as the Barnard Catalogue.
This is a 2-panel mosaic of part of the Taurus Molecular Cloud (TMC-1), which is an interstellar molecular cloud in the constellations Taurus and Auriga. This cloud hosts a stellar nursery containing hundreds of newly formed stars.
The blue area in the image is a reflection nebula known as LBN 782, which lies within both dark nebulae, Barnard 10, and Barnard 7. The dark area of nebulosity stretching away from LBN 782 towards the left of the image comprises Barnard 211, 213 and 216.
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.
