For testing on film my newly arrived exceptional French 35mm camera FOCA Universel RC (see below for details about this rare and fascinating camera), I went for photowalk in my district, Lyon, France. The weather was very sunny and the outside temperature warm (32°C).
Testing a new collection camera is always is great moment. We know the camera only from its blank manipulations but the real judge is the test film on the field, the camera exposed to outside elements in real photography operations. Some possible problems as light leaks or slight unpairing of the shutter curtains, will be only detected on film.
I used the camera with its ever-ready bag and I removed the front part for operation. In particular, I previously checked very carefully the exact condition of the thin leather neck strap. Old leather may crack and it would a shame and a nightmare to drop such camera. The OPLAR standard lens 1/:2.8 f=5cm was equipped with a yellow filter FOCA x2.5. The OPLAR lens fro the FOCA’s only accept push-on filter (42.5mm in this specific case). A vintage Genaco cylindric stainless-steel shade hood conceived for a 5cm focal length was also used all along the session.
The test film was a 36-exposure Fomapan 100. Expositions were determined for 50 ISO to compensate the absorption of the yellow filter. Metering was achieved using a Minolta Autometer III lightmeter fitted with a 10° finder for selective metering privileging the shadow areas.

After completion at view #39, the film was rewound normally and processed using 350 mL of Adox Adonal developer (identical to the original Agfa Rodinal in its formula of 1891) prepared at the dilution 1+50 for 9 min 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 14.4) 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.
As a result, the test film shows that this FOCA Universel RC is in perfect conditions and could be used normally with confidence.
About the camera and its history :
Among the French 35mm camera produced by « Optique & Précision de Levallois S.A. » from 1945 to the middle of the 60’s, the FOCA Universel « RC » is likely the most captivating ever produced in France at that time.
The camera was the last development of the FOCA, sometime called the « French Leica » because the optical and mechanical precision matched and even surpassed the original thread-mount Leica. Far before the first Leica M (the M3 in 1954) O.P.L. developed a bayonet-mount FOCA in 1948 called the FOCA « Universel ». Seeing the incredible viewer and range finder of the Leica M that is likely the most sophisticated system even engineered, O.P.L. released lately a great improvement of the FOCA with a novel collimated, parallax auto-corrected, of a fully original and different design of the Leitz system.
The FOCA Universel RC It is a rare camera that only appears for time to time on the collector market, being only produced to a bit more than 2000 overall units in the years 1962 and 1963, just before O.P.L. decided to quit the camera production and returned to other instrumental optical production. O.P.L. soon merged with SOM Berthiot and today can be found still in the industrial filiation of SAFRAN group, the French leader company for designing and producing system for aerospace appliances. The plant where the FOCA's were produced still exists in an almost original form in Châteaudun, Eure-et-Loir, France.
I got my first FOCA URC unit two years ago (Sept. 2023, flic.kr/s/aHBqjAV6Dg) that is a standing and emotional piece of my small camera collection.
I got this one from an apparently ignored auction on the French eBay. We were only two biders in the last 5s and I won the auction not far away to the initial price. The camera was fully revised, with new shutter curtains, a new delayed shutter release mechanism. The serial number indicated a year-1962 production starting with 1.000.000, closed to my first FOCA URC. The camera works in every functions like on its Day-1! The camera came with a late version 1962 of the OPLAR 1:2.8 f=5cm standard collapsible lens of excellent quality, the FOCA UCR dedicated ever-ready leather bag with the original leather neck strap in good condition.
The original O.P.L. camera warranty and a registration postal card fortunately followed the life of the camera, indicating that this beautiful FOCA Universel RC was sold to its first owner on August 9, 1963 by the official FOCA dealer « ROYAL-PHOTO, Photo-Ciné-Magnétohone », 42, rue Vignon, Paris 9ème arrondissement, France, today a Weill fashion shop at the same address. The address of the owner also still exists with the original Parisian building in place, Boulevard Poniatwski, next to the Métro station « Porte de Charenton », Paris 12ème arrondissement.
The shown original FOCAL Universel RC user manual is the one that came with my other FOCA URC camera.
These information pushed me to question what were the news in France on this Friday, August 9, 1963… France was mainly on vacation, by an exceptional wet and fresh weather that wasted many French citizens holidays. The whole national radio information bulletin is still available online here :

June 14, 1963: a particularly cool day - it was no more than 12°C in Rouen, 13°C in Paris, St. Quentin, Lille, Le Havre, and Caen.
August 1963 was autumnal because it was very cool and very wet. On August 3, 1963, torrential rains caused catastrophic flooding and the death of eight people in the Lyon region. On August 4, 1963, 400 houses were also flooded between St. Jean de Luz and Le Boucau (Pyrénées Atlantiques). On August 17 and 18, 1963, it was no more than 10°C. and 15°C in the northern half - many summer visitors leave early - it's snowing in the mountains and the harvest is very difficult.
Historical landmarks of the year 1963
August 28, 1963: Martin Luther King leads the march on Washington. October 11, 1963: Jean Cocteau and Edith Piaf die within hours of each other. November 22, 1963: President J.F. Kennedy is assassinated in Dallas. The yé-yé movement is in vogue - the debut of Françoise Hardy and the politically engaged singer, Jean Ferrat.
This is an unusually rich view of the Earth's telluric absorption spectrum obtained using the addition of many spectra of the underside of a dark thundercloud obtained in Munich in August 2014. More details of these observations can be seen at:
www.flickr.com/photos/bob_81667/49778550932/in/album-7215...
The Solar altitude at the time was 45° and so the normal telluric spectrum of the sky would be weak and rather unimpressive. In this case however, the light reaching the spectrometer had experienced a long path through the towering cloud and had scattered many times from water drops, other aerosols and air molecules with much of the path happening at low altitudes where the pressure is highest.
Such a random walk through the cloud can accumulate a long pathlength's worth of travel through a medium that will contain a high proportion of absorbers and scatterers such as water that predominate at low altitudes.
One species that will be under-represented is ozone (O_3) because this gas is only present in any quantity above about 12km — although some will be produced locally by lightning flashes.
Another oxygen 'molecule' however will be over-represented since its density depends on the square of the gas pressure. This is tetra-oxygen (O_4) which is a transitory (very short-lived) association of two oxygen molecules that allows the formation of spectral bands from normally electric dipole forbidden transitions. These O_4 bands are called Collisional Induced Absorptions (CIA). The short lifetime of these collision interactions results — basically because of Heisenberg's Uncertainty Principle — in spectral lines being substantially broadened. This process was only discovered in the mid-20th century and the full quantum-mechanical explanation has only recently been explored by Tijs Karman and co-workers in the Netherlands (Karman, T., Koenis, M.A.J., Banerjee, A. et al. Publisher Correction: O2−O2 and O2−N2 collision-induced absorption mechanisms unravelled. Nature Chem 10, 573 (2018). doi.org/10.1038/s41557-018-0063-2).
These distinctive absorption bands were seen by the 19th century observers such as Ångström and others at sunset and sunrise but, although they realised that the bands behaved differently from those due to water vapour and the normal O_2 molecule, they were not able to identify them.
The green and violet lines in the plot show processed versions of the observed cloud spectra which have been normalised by a process described in the previous posts referred to above. This results in a flat continuum which is free from all of the absorptions in the Sun's atmosphere: the Fraunhofer lines have gone.
The thin violet spectrum contains all of the telluric features including the complex spectrum of nitrogen dioxide (NO_2) which occupies the blue and green part of the spectrum only. The thick green line has the NO_2 spectrum removed assuming a column density of 2.5e17/cm2. This rather high density is probably predominantly the result of the formation of NO_2 in lightning flashes and not necessarily by vehicle exhaust pollution. Cross-section data for NO_2 can be obtained from:
www.frontiersin.org/articles/10.3389/fenvs.2019.00118/full
A model of the computed O_4 spectrum corresponding to a column of 2e44 cm^5 molecule^-2 using the HITRAN database ( www.sciencedirect.com/science/article/pii/S0022407311003773 ) is shown as the dashed red line.
In this case the telluric spectrum is dominated by the the bands of water vapour whose strength increases towards the infrared. These are overtones (harmonics) of the fundamental vibrations of the water molecule that include symmetric and asymmetric stretch of the two hydrogen atoms with respect to the central oxygen, the oscillation of angular separation of the hydrogens around a mean angle of about 105° and librations around three axes (see: www1.lsbu.ac.uk/water/water_vibrational_spectrum.html ). These higher harmonics cause depths of a metre or so of clear water to appear blue. See my discussion of water spectra at: www.flickr.com/photos/bob_81667/6309336354
The spectra also include emission from some lightning flashes (the spectra were selected to avoid strong lightning flashes) which have not been marked but can be identified by looking at:
www.flickr.com/photos/bob_81667/4951867947/
Note that there is no visible sign of ozone which only dominates the spectrum near twilight.
I have included on the plot overlays of two of the maps of the atmospheric spectrum made by Ångström. The top one, made by Ångström and Thalén is taken from the book "Spectrum Analysis" by H. Schellen published in 1872 and reproduced by the Scholarly Publication Office of the University of Michigan University Library (which I gratefully acknowledge as the source) as part of Plate VI.
The second map (left-right mirrored) is from the same volume as Fig. 95. While these two maps are very similar, there is a significant change in the position of the blue absorption band marked as Greek(lambda) in the lower map. What is apparently the same band appears shifted some 14nm to the blue. This band, which appears strongly in my cloud spectrum at a wavelength consistent with the lower map, is hard to see in a visual spectroscope (I have yet to observe it!) and one can perhaps excuse Ångström — who is renowned for his exquisite precision — for getting it wrong the first (?) time. Remember that he did not have access to the digital manipulation of spectra that I have now! He had to disentangle the telluric spectrum from that of the sun by eye, a task that is considerably easier in the red than in the blue.
Since all of these telluric features result from transitions in molecules, they tend to be more frequent and stronger towards longer wavelengths, leaving the visible and ultraviolet spectrum dominated by atomic processes. It is perhaps remarkable that some of the most obvious features to our eyes are due to the somewhat esoteric and only lately understood process of CIA. Indeed, the yellow/orange part of the spectrum seen through a spectroscope is dominated by an almost transparent region between about 580 and 590nm that is bounded on the blue side by the strongest O4 band at 576nm and, on the red side, by "The Rainband" of water from 590 to just over 600nm. This leaves what almost appears as a yellow/orange emission band in the region of the spectrum to which our eyes are most sensitive.
Another interesting telluric spectral feature can be see at the violet end of this spectrum, again enhanced in the cloud spectrum due to the long high pressure pathlength of the light. The majority of scatterings of photons by molecules or aerosols in the atmosphere are 'elastic', ie. do not involve a change of wavelength between the incident and the scattered photon. A small fraction are however 'inelastic', meaning that some energy is transferred from the photon to produce internal vibrations in the molecule. [Note that this process can happen in reverse but that is very rare and most of the outgoing photons are redder that the original one.]
In the case of the solar spectrum scattered in the Earth's atmosphere, especially in clouds, a small fraction of the photons at each wavelength will be Raman scattered towards longer wavelengths. If the Solar spectrum was perfectly flat, this would make little difference. When there are strong, deep absorption lines however, more light will be scattered into an absorption line than out of it. This will result the spectrum of skylight having slightly shallower lines than the Fraunhofer absorption lines in in the Sun. See the discussion of the phenomenon in:
www.researchgate.net/publication/253321609_The_Ring_Eect_...
This process, called Raman scattering after the Indian Nobel Laureate in physics (1930) who discovered it with his student K. S. Krishnan, is now very widely used in science, technology and forensics to study and identify materials of many sorts. When we remove the Solar lines by dividing our cloud spectrum by the Sun, we can see the strong lines appearing in apparent 'emission'. The Ca II H & K lines, being the strongest is the spectrum, offer the best chance of seeing the effect appearing in our plot.
This nice example of a telluric spectrum gives an idea of the kind of spectrum that we might hope or expect to see from an exoplanet in the 'habitable zone' orbiting another sun-like star when our instruments allow us the capability to see this level of detail (which may take a while!)

A dark nebula or absorption nebula is a type of interstellar cloud, particularly molecular clouds, that is so dense that it obscures the visible wavelengths of light from objects behind it, such as background stars and emission or reflection nebulae.
Dark clouds appear so because of sub-micrometre-sized dust particles, coated with frozen carbon monoxide and nitrogen, which effectively block the passage of light at visible wavelengths.
The main molecular clouds are annotated according to SIMBAD.

These scans are from a short trip to Portugal during my first year learning to shoot develop black & white 35mm film. The Voigtlander R2M was the camera at the time paired with Tri-x 400. I enjoyed how remote and scenic the countrysides were. The weather was cold and overcast most of the trip with small windows of sunlight. Street photography in this city was a joy as well! Lately I've been re-scanning my negatives with the Plustek 8300 AI and Im impressed at the information it can pick up. I highly recommend it. The scanner comes with Silverfast SE software and as a final step I convert the DNG Files with Negative Lab Pro's Lightroom plugin.

ABOUT THE ARTIST
Chance Nkosi Gomez known initiated by H.H Swami Jyotirmayanda as Sri Govinda walks an integral yogic path in which photography is the primary creative field of expression. The medium was introduced during sophomore year of high school by educator Dr. Devin Marsh of Robert Morgan Educational Center. Coming into alignment with light, its nature and articulating the camera was the focus during that time. Thereafter while completing a Photographic Technology Degree, the realization of what made an image “striking” came to the foreground of the inner dialogue. These college years brought forth major absorption and reflection as an apprentice to photographer and educator Tony A. Chirinos of Miami Dade College. The process of working towards a singular idea of interest and thus building a series became the heading from here on while the camera aided in cultivating an adherence to the present moment. The viewfinder resembles a doorway to the unified field of consciousness in which line, shape, form, color, value, texture all dissolve. It is here that the yogi is reminded of sat-chit-ananda (the supreme reality as all-pervading; pure consciousness). As of May 2024 Govinda has completed his 300hr yoga teacher training program at Sattva Yoga Academy studying from Master Yogi Anand Mehrotra in Rishikesh, India, Himalayas. This has strengthened his personal Sadhana and allows one to carry and share ancient Vedic Technology leading others in ultimately directing their intellect to bloom into intuition. As awareness and self-realization grows so does the imagery that is all at once divine in the mastery of capturing and controlling light. Over the last seven years he has self-published six photographic books, Follow me i’ll be right behind you (2017), Sonata - Minimal Study (2018), Birds Singing Lies (2018), Rwanda (2019), Where does the body begin? (2019) & Swayam Jyotis (2023). Currently, Govinda is employed at the Leica Store Miami as a camera specialist and starting his journey as a practitioner of yoga ॐ
Two versions of a sketch of the visual spectrum of the setting Sun showing the prominent telluric lines towards the red end.
The bottom spectrum shows lines in black and diffuse bands in grey as they would appear in the spectroscope.
In the top spectrum, the telluric features are coded in blue (for water vapour absorption), red (for diatomic oxygen) and brown (for tetra-oxygen).
A few of the strong Solar Fraunhofer lines are shown in black and marked with their designations (C – h) in black letters.
Greek(alpha) marks the combination of ordinary diatomic oxygen absorption and a broader contribution from the collisionally induced transition in the transitory association of two oxygen molecules called tetra-oxygen. Greek(delta) marks the strongest visible tetra-oxygen absorption at ~576nm.
'r' marks the water absorption that was known in the late nineteenth century as The Rainband since there were attempts to use it as a predictor of rain.
These three features along with the water band that encompasses the H-alpha line 'Fraunhofer C' are the most visually prominent telluric features.
I find it interesting that two of these features are associated with an absorption process that was not identified until 1949 ( en.wikipedia.org/wiki/Collision-induced_absorption_and_em... ).
The 19th century scientists had appreciated that these two bands behaved differently from the water absorptions and became stronger more rapidly as the Sun approached the horizon. However, they had no idea what caused them.
The yellow gap between r and delta appears as a very prominent structure in the visible spectrum of the daytime sky, particularly at dusk and dawn.. The yellow almost looks as if it is an emission band superimposed on the Solar spectrum!
The coloured background spectrum in these illustrations is derived from my own photograph, taken with a full-spectrum digital camera, of a dispersed quartz-halogen lamp using a slit and a 60° glass prism.

Yesterday I was lucky enough to have free tickets to the Braque expo at the Grand Palais. I didn't know this artist before and was very happy to discover his work which has a very wide variety of styles. If you have the opportunity, go discover!
Having just done the series of 6 photos where there was indifference also, it was interesting to see yesterday that everyone was absorbed! I've decided to do this series in black and white to focus on the people rather than the art. However, I'd definitely recommend this artist to you :)
Hier j’ai eu la chance de pouvoir aller gratuitement à l’expo Braque au Grand Palais. Je connus pas cet artiste et fut heureuse de découvrir son travail qui a changé en plusieurs styles très différents tout au longue de sa vie. Si vous avez l’occasion, découvrez-le ! (Demain c’est le dernier jour au Grand Palais.)
Puisque j’ai fait très récemment cette petite série « immersion et indifférence » j’étais très sensible aux autres visiteurs … et cette fois-ci tout le monde était immergé ! J’ai décidé de montrer ces photos en noir et blanc car j’ai voulu mettre en valeur les personnes et non pas l’art. Mais je vous recommande vivement cet artiste :)
If you recognise yourself in these photos and prefer they are not here, just let me know (or if you would like a copy of the photo).

5 year old Emma arrived in the Atelier with "a broken arm". She had administered first aid on herself using paper to create an arm cast. Then she set to work with her ink experimentation, using the dropper to carefully compose her colours. She chose "purple - as it's a magical colour" and "green for emeralds" . Somehow, "the broken arm" enabled her to focus even more as she cautiously applied the ink to the fabric.

I felt today also warranted being off, as mentally I’m not convinced I’m completely over the last of our joyous child inherited illnesses, even if physically I think I’m back there. Possibly decreased absorption of compounds is the primary cause of this today. Anyway, I made myself available to people to run through things with me before planned meetings and, following a lengthy call, decided to head into town to try and clear my head, mirrorless and two lenses in tow.
I’ve not really used the zoom lens that came with my M100 very much, possibly because I’ve favoured the pancake lens as primes are generally better. However, kit lenses are clearly much improved over the days of my old school 18-55mm that came with the 400D. Apparently I can correct the barrel distortion and vignetting, but these are features I like, so I shall not.
The trip left me with a new book from the library (the next from Andy Weir) as well as many shots that I liked and so have the trauma of choosing which to have as ‘the’ photo for the day. It is for this reason that I think I will do a Project 52 next year, but along the lines of that from 2016 when I had a self imposed 3 photos a week allowance for it, the rationale being that it gave me scope for themes and to explore those within just a few frames.
Tips to avoid a hangover
Follow these tips to keep hangovers at bay:
Don't drink on an empty stomach. Before you go out, have a meal that includes carbohydrates (such as pasta or rice) or fats. The food will help slow down the body's absorption of alcohol.
Don't drink dark-coloured drinks if you've found that you're sensitive to them. They contain natural chemicals called congeners (impurities), which irritate blood vessels and tissue in the brain and can make a hangover worse.
Drink water or non-fizzy soft drinks in between each alcoholic drink. Carbonated (fizzy) drinks speed up the absorption of alcohol into your system.
Drink a pint or so of water before you go to sleep. Keep a glass of water by the bed to sip if you wake up during the night.
---------------
The morning after
If you wake up the next morning feeling terrible, you probably didn't follow this advice. Although there are no real cures for hangovers, there are ways to ease the symptoms.
Treatment involves rehydrating the body so it can deal with the painful symptoms, though the best time to rehydrate is before going to sleep.
Over-the-counter painkillers can help with headaches and muscle cramps. Paracetamol-based remedies are usually preferable, as aspirin may further irritate the stomach and increase nausea and sickness.
Sugary foods may help you feel less trembly. In some cases, an antacid may be needed to settle your stomach first.
Bouillon soup, a thin vegetable-based broth, is a good source of vitamins and minerals, which can top up depleted resources. Its main advantage is it's easy for a fragile stomach to digest.
You can replace lost fluids by drinking bland liquids that are easy on the digestive system, such as water, soda water and isotonic drinks (available in most shops).
"Hair of the dog" – drinking more alcohol – does not help. Drinking in the morning is a risky habit, and you may simply be delaying the appearance of symptoms until the alcohol wears off again.
If you've had a heavy drinking episode, hangover or not, doctors advise that you wait at least 48 hours before drinking any more alcohol to give your body tissues time to recover.
Sometimes, of course, a hangover makes that advice easier to follow.

I managed to capture this spectrum of the partially clear sky above the Sun direction about 12min after it set on 8 December in Bath UK. I used my old Beck Wavelength Prism Spectroscope on a stand and held a phone camera up to the eyepiece.
The photograph is straddled by my two drawings of a prism spectrum which show the telluric features marked: red/brown for oxygen and blue for water bands on the top.
I post it here since it shows rather clearly the structure in the yellow part of the spectrum with the clear, visually prominent, unabsorbed yellow band between 580 and 590nm.
At this time, the air was clear and dry and so the water bands are relatively weak. The tetra-oxygen features at 577 and 630nm are strong however, especially the one in the yellow/green which dominates the the visual appearance of the spectrum. Having said that the water absorption bands are relatively weak, it seems as if the band around 500nm could be visible as a slight but noticeable shading in the prism spectrum. It is in the right place and is marked on the Ångström maps.
Although the photograph does not show the far red bands because of the detector filtration, I can see beyond the Fraunhofer A-band to about 800nm when looking at the setting sun with a small diffraction-grating spectroscope. [Don't look directly at the sun, even with a spectroscope, when it is bright and higher in the sky — unless you know what you are doing!]
However, my ageing eyes no longer allow me to see clearly the Fraunhofer H & K lines between 395 and 400nm.
Schwarz: Bezeichnung der Farbempfindung, die entsteht wenn kein Farbreiz wahrgenommen wird.
Schwarz ist die Absorption aller Spektren des Lichtes. Abwesenheit von sichtbarem Licht jeglicher Wellenlänge - und somit die Abwesenheit von Farben.
Schwarz ist eine unbunte Farbe.
Die Buntheit der unbunten Farben ist Null.
Durch verschiedene Helligkeitsstufen des Unbunt ergeben sich die Schattierungen von Schwarz über Grau bis Weiß.
Pigmente und Färbemittel, die mehr Licht absorbieren als reflektieren ERSCHEINEN schwarz.

Yesterday I was lucky enough to have free tickets to the Braque expo at the Grand Palais. I didn't know this artist before and was very happy to discover his work which has a very wide variety of styles. If you have the opportunity, go discover!
Having just done the series of 6 photos where there was indifference also, it was interesting to see yesterday that everyone was absorbed! I've decided to do this series in black and white to focus on the people rather than the art. However, I'd definitely recommend this artist to you :)
Hier j’ai eu la chance de pouvoir aller gratuitement à l’expo Braque au Grand Palais. Je connus pas cet artiste et fut heureuse de découvrir son travail qui a changé en plusieurs styles très différents tout au longue de sa vie. Si vous avez l’occasion, découvrez-le ! (Demain c’est le dernier jour au Grand Palais.)
Puisque j’ai fait très récemment cette petite série « immersion et indifférence » j’étais très sensible aux autres visiteurs … et cette fois-ci tout le monde était immergé ! J’ai décidé de montrer ces photos en noir et blanc car j’ai voulu mettre en valeur les personnes et non pas l’art. Mais je vous recommande vivement cet artiste :)
If you recognise yourself in these photos and prefer they are not here, just let me know (or if you would like a copy of the photo).
Si vous vous reconnaissez dans cette photo et préfériez que la photo ne soit pas publiée, dites le moi (ou bien si vous aimeriez en avoir une copie).
