Another frame from the RPX100 test roll.
Camera: the Minolta Autocord, film developed in PMK (Pyro).
Unfortunately I overestimated the reciprocity required for this film and got some severely dense negs. But PMK saved the day, at least somewhat. The higher values on this negative were fairly compressed, but I was still able to make a decent image from it. I will likely try again tomorrow morning.
RPX100 has some great grey values, plenty of sharpness and seems forgiving of overexposure. I strongly suspect this is actually a variant of Kentmere 100 (exact same grey film base, by the looks).
NOON pinhole camera 6x12 model at 6x9. The light weather shifted fast, from almost sunlight to dark skies and heavy rain, most of the latter. The exposure coud be all from 5 to 30 minutes. I decided 22 minutes, and the result is decent. Pinhole photography is always a qualified quessing in the combination of f-stop, focal length, ISO and reciprocity.

Between Aquarius and Luna Duo, revolving languidly, like an ivory Ferris wheel, the Stonehenge Intergalactic Spacefort monitors star systems both near and remote, ceaselessly seeking extra-terrestrial life for friendship, and maintaining vigilance for potential threats to the Interstellar Reciprocity Coalition, IRC.
One of the planets belonging to the IRC is Hypatia, a garden planet of serene beauty where philosophers, scientists, and artists from all over the galaxy live and work in harmony. But something unexpected and terrifying is about to shatter that tranquility, drawing Terran IRC Civilian Oversight Chief Plush Tusch, Terran IRC Captain Debris Jetsam, and IRC Aquarian Major Scrumptious Sky into an evil web intended to snare the entire galaxy!

This is a film shot that I took with one of my Rolleiflex cameras at the end of January. I was really looking forward to finally getting these scans back from the lab as I had tried something with this roll of film that I'd never tried before using a Rolleiflex TLR and that of course was to use an ND filter on it. This was a 43mm circular filter, made by K&F Concept, that I picked up on eBay for around £15 which now seems like the deal of the century. It's interesting to compare this shot with the last shot I put up which was taken digitally using a Lee ND filter and where I commented on the blue colour cast that the Lee filter left on the photo. What you see with this shot is very close to what was recorded on the film in terms of colour. I tweaked it with a bit of clarity and contrast and that's about it. I suppose the bad news is that I only tried two of these LE compositions as I was so unsure of myself shooting LEs on film that I only chanced three shots on the roll (1 of which I screwed up). But at least now I know it worked. BTW, if you wonder why I thought shooting long exposures on a TLR might be a challenge look up the term reciprocity!
Ten days ago I had abdominal surgery and I've not felt up to making photographs, but yesterday I decided to just make a couple exposures "to exercise my creative brain" if nothing more.
I exposed two 5x7 sheets of Fomapan 100 @ 50 ASA and developed one in Thornton's 2-Bath developer, and another in PMK. This image is from the Thornton negative. I’ve used Fomapan sheet film for a couple years now and I find it to be a very capable product, and aside from its reciprocity characteristics, it’s a very attractive option at a remarkably good price. I buy FP4+ occasionally and have a cache of it in the fridge, but at nearly $10 a slice for 8x10 sheets of it, it’s hard to justify this price and I expect I will limit how much of it I buy in the future.
The differences between the two developers are very subtle and aside from the Pyro stain on the PMK neg, the two negatives scan almost identically. (They'd print differently in the darkroom, though) Anyway, this was a happy exercise and it felt good to make some new work.
Camera: 5x7 Intrepid with my 8.5" Kodak Commercial Ektar lens (a beautiful thing!)
I'm doing more large format materials testing - comparing developers and how they act on certain films. I've recently become aware of how good certain older, simple developers can be, specifically Divided D-23. I exposed two sheets of Bergger Pancro 400 identically, and processed one in Xtol 1:1 (which is one of my standards) and the other in Divided D-23*
This image was the one processed in DD-23
The difference? Normally I would think of Xtol as the perfect developer for delivering full emulsion speed, contrast, shadow information, and retrained highlights. But in comparison with the DD-23 negative, the Xtol neg was far more contrasty and the brightest values were far hotter than I wanted. The DD-23 negative was beautiful; excellent contrast, good shadow values, excellent tonal separation, and the highest values were much more restrained/balanced than the Xtol negative. This, frankly, surprised me. I expected the two negatives to be much more alike.
This prompts me to continue exploring the Divided D-23 option, and maybe try Divided D-76 as well. Of course, you don't want to apply this technique to any and all images, as there may be too much contraction of the tonal scale in low contrast situations. I knew that with the contrasty window lighting, and the fact that this was a 90 second exposure, contrast was going to be quite strong. You might not think so, looking at the image, but directional light can be contrasty even when its subdued window light on a cloudy day. And of course, reciprocity builds in more contrast too - something to be aware of.
Camera: 8x10 Deardorff
Lens: Gundlach Turner-Reich 12" convertible, both cells used. This is a 100 year old lens (give or take), and in spite of its limitations its capable of making spectacular photographs. This is one of the better lenses for giving very soft out-of-focus areas, devoid of vibrations or aperture shapes, etc. (many lenses fare really poorly in this regard. My Hasselblad is one of the worst, with its pentagonal bokeh!) If it was good enough for Edward Weston, its good enough for me.
Exposure: 90 seconds at f22
Anyway, this was mostly just a technical test image, but I hope you enjoy it just the same. I have a second image made in the same way that I like much more and I'll post it shortly.
Divided D-23 is a two part developer; the developing agent + preservative in Part A, and the accelerator in Part B
In this case, Part A was 3 grams of Metol and 50 grams of Sodium sulfite in 500 ML of water, and Part B was 2 grams of Borax in 500 ml of water.
Depending on the film, time in Part A is between 4 and 12 minutes, and time in Part B is pretty much a constant: 3 minutes, plus or minus.

An art installation "Karanakuy" by Raul Ayala inside the Green-Wood Cemetery Chapel. On view from October 28 to November 17, 2024
Since 2018 Green-Wood Cemetery has commissioned an altar inside their historic chapel for the "Day of The Dead" holiday
From the website:
This year’s altar, created by Raul Ayala, pays homage to the traditions of the Ecuadorian Andes, where November 2nd is celebrated as Día de los Difuntos (Day of the Deceased or All Soul’s Day).
Karanakuy is a Kichwa word that embodies the concept of giving as an act of reciprocity. The altar weaves together elements that invite visitors to engage through their senses, utilizing plants, fruits, and culinary traditions from the Andes. Traditions associated with Día de los Difuntos includes two distinctive culinary items: guaguas de pan, sweet bread figures shaped and decorated like babies, and colada morada (or its fermented version, yana api), a thick beverage that is made with fruit and spices and used in rituals and celebrations tied to the agricultural calendar.
Inspired by guaguas de pan, visitors are encouraged to craft their own offerings for the altar by shaping fondant into doll-like figures or objects commemorating their departed loved ones. They may also leave personal items, such as mementos, photos, or flowers, upon the altar. The large urn at the center of the Chapel will be filled with yana api as an offering to those who have passed.
Another photo made with Fomapan 100 (rated at 50 ASA) the same morning, but this image dod not require reciprocity adjustments, so getting the exposure correct was easy (1/2 second at f16)
Intrepid 5x7 with the 8.5" Kodak Commercial Ektar lens. Fomapan developed with Photographers Formulary FA-1027 1:14, 9 minutes. Excellent developer, I always have it available. Far superior (IMO) to Rodinal.

==================================================
Picture taken with a Linhof Technika II 13x18 cm. camera made c.1947; Schneider-Kreutznach Angulon f6.8 / 120mm lens; Fomapan 100 film, 6:15 min. of exposure, at f13 compensating for the large reciprocity failure (the photo meter indicated only 30s., at EV 2).
First trials at urbex.
From an 8x10 inch Fomapan 100 negative (well, branded as CatLabs X80, but it's Fomapan) developed in PMK Pyro. Not bad, but the shoulder rolls off very early, making for somewhat difficult to visualize high values. But it works in its own way.
Deardoff with Schneider 240mm Symmar-S
40 seconds exposure at f16. (Long reciprocity + bellows extension)
One of the few frames of Ektachrome from my last trip that came out how I expected.
Reciprocity failure is a bitch.
I am evaluating the CatLabs X80 II film for use in my Salted Paper printing process. This is a first test exposure.
It is weighing on me that Ilford FP4 - as much as I love that film - is approaching the very limit of my budget. Once it hits $200 for a box of 25 sheets, I'm going to have to bid it farewell, sadly.
And so I've bought some 8x10 CatLabs X80 II sheets to test, even though I have issues with how CatLabs promotes (or should I say occludes) its products properties. (basically, CatLabs provides ZERO technical data about their films, and if asked, they refuse to provide any)
Since I am making negatives specifically for salt printing (which requires extra contrast and density in the negative), I made some assumptions about this new film and handled it almost exactly as I do FP4. I exposed it at 64ASA, and developed it in double strength PMK (pyro) developer, which gave me a very good negative, from which the scanned image here was made.
I'm pleased that the negative I got was almost ideal for salt printing: just the right contrast index, density and a base fog density that is almost as clear as FP4 (but not quite). So, although this film lacks ANY documentation data (no reciprocity values, no characteristic curves, nothing), it does appear that it will be suitable for my needs. I don't mind the fact that it will save me $70 over the price of FP4.

Negative was an interesting Agfatone P330p, medium contrast. Nothing to find on the web. In a previous session I had overexposed and overdeveloped for at least 5 stops, now I sort of got it OK-ish by metering at 100iso, applying no reciprocity failure factor and using stand development in R09 1:100 for 1 hour....

Something I shot over the summer at Falls of Ohio Park on TMax 400 film. I rarely use that film because the reciprocity failure curve favors TMax 100 at the exposure times that I regularly use. Not sure why, but the scene seems a unusually hopeful for me. Maybe we all need to capture that glimmer just a bit more often.
Hey, all because I like to use my century-old cameras doesn't mean that I can't enjoy using the phone sometimes too, right?
The workflow of those old cameras, at night, is pretty much:
>Load film properly
>Tape up light leaks in camera
>Find a good spot for a picture
>Measure light to determine exposure settings
>Measure light with a different device to confirm
>At nighttime, factor in the reciprocity
>Set camera to "B" (bulb) setting
>Secure the camera to keep it steady
>Carefully monitor exposure time elapsed
>Repeat as needed!
Whereas, the phone is:
>Look
>Shoot
>Repeat as needed!
Subjects who reciprocally recognize each other as such, must consider each other as identical, insofar as they both take up the position of subject; they must at all times subsume themselves and the other under the same category. At the same time, the relation of reciprocity of recognition demands the non-identity of one and the other, both must also maintain their absolute difference, for to be a subject implies the claim of individuation. - Jurgen Habermas
A lua que brilha pra cidade. A cidade que brilha pra lua. E é nessa reciprocidade que se segue.
The moon shining to town. The city shining to the moon. And it is this reciprocity that going.

Made a pinhole camera out of a cylindrical tin but results have been poor.
Today the reading was 1/100th at f8 on ISO 125 (Ilford FP4+) which converted to 10 seconds on the pinhole camera. With reciprocity dialled in that made 20 seconds. Cropped from original 5x4.
Developed in Rodinal 1+25 for 7.5 minutes at 20C.
At last an image! It won’t win any awards but still satisfying for a nerd like me 😂 ;))

It all started with a walk
and a wholly natural talk
to myself, within myself
the reciprocity of oneself
steps, flight, buds and lines
intertwined we are what life defines
take it gratefully and do not begrudge
the neighbourly world we so often prejudge
stop! a moment! you are still, the world still
turning in your presence of mind and will
cherish what you embrace and desire
from deepest heart the beauty you admire
never admonished when true and pure
for each step of life is evidence to endure,
to succeed where moods failed before
just another step will build and restore
faith in your soul, belief in the whole
entity of being who you are and who to console
for the giving and understanding of one another
is the embracement of the en-stepping venture
and it all started with a little walk
and nature's soft, silent talk...

Songs of Reciprocity is a series of windscreens located along Burnhamthorpe Road. The artworks incorporate organic and geometric patterns from four distinct environmental ecosystems: Lichen fields, coral reefs, mycorrhizal fungi networks, and bee colonies. They celebrate the theme of reciprocity through community, generosity, resilience, strength, creativity, agency, and liveliness of all living entities. The artwork highlights the mutually beneficial relationships vital for well-being and honours the relationship between people and nature.
The organic and geometric patterns in the designs complement the surrounding architectural features and nearby green spaces. The implications of reciprocity in the artworks will further inspire meaning in the local community’s daily life through this compelling art.
"Being here outshines taking something from here" wrote Seth Kantner in his book Shopping For Porcupine. At the other side of the world, these words have just as much relevance.
Within this 'here' is an ancient balance.
It gives us the air we breathe, and nurtures us, body and soul. In return, we must give to and nurture it.
This is the dance of reciprocity.
It is a pact from the depths of time.
I made this photograph with the Intrepid 4x5 and the 100mm Wide Field Ektar. I was recently told the Wide Field Ektar is not only an excellent landscape lens, but also makes a respectable lens for close-up work.

This was my second try with Ektachrome after some 'learning experiences' with my first. Still getting the hang of it... Most of my pictures from the early morning came out underexposed, either from metering for the wrong part of the scene or forgetting to account for reciprocity failure. Still though, I really like the low key look of this frame with the distant hill sticking out of the clouds.
Give it another few months and I might try butchering another roll of slide film
I finally did some film testing and was able to get a reliable asa and a development time. I also changed my reciprocity graph as well. The negatives look denser and the contrast is better. This should make my negatives easier to print, in due time.
