This is the first time I've used movements to control my plane of focus as well as perspective. I had rise, tilt, and swing on the front standard here, getting both gate leaves in focus and keeping...

I've been away for a while, but I haven't forgotten large format. I had my Graphic View out a few weeks ago, and there was this little copse of tall trees...

I've processed the original CMS 20 in both a PQ low contrast developer (home mixed version of H&W Control) and in Caffenol LC+C, which I originally created for Fuji and Agfa microfilm stocks. Both...
I'll add a plus one here. For roll films, you can buy everything you need to process negatives at home (stainless daylight tank w/ 120 reel, thermometer and chemicals, changing bag optional) for not...
It might be worth looking back to reversal processes intended for Tech Pan; there are similarities between that film and the document films that are the basis of CMS 20, including the use of very low...
I've also used the Impossible 600 B&W, in SX-70 Model 2 and Model 3 cameras, with very good results (turn the brightness dial all the way down, or almost, and it works fine in the 150 speed cameras)....
Your mark is light on the negative, and not sharp. I think it's the shadow of a hair inside your bellows. Static would be dark on the negative.
What I did when I shot 35 mm a lot was, if I shot at 400, I developed with the time for the Foma 400. Contrast ran a little higher than shooting 400 at 400, but not much. You could (and I did)...
I've used Caffenol LC and Caffenol LC+C (low contrast versions of Caffenol) for microfilm stocks, including Adox CMS20, which are (relative to contrast and resolution, though not in spectral...
I've used Fomapan 100 (and Arista .EDU Ultra 100, same film relabeled) in 35 mm and 9x12, processed in HC-110 Dilution F, Parodinal, and Caffenol. I was very pleased with it, and felt it gave all...
Bingo!
I've seen many reports from stand development users in all formats that are consistent with concentration-driven flow across the film -- what you're seeing in the middle/late part of...
No, in my opinion, not too much fog. I like the way the far shore and house fade, while the foreground rock is still sharp.
First, we need to clarify whether this is increased or decreased density at the top (as placed in the tank). Underdevelopment would be reduced density and contrast, while overexposure due to a light...
You might be right -- though I can see these things requiring ID or having quantity limits (and resulting prohibitive pricing) long before they become completely unavailable. Simple strike-anywhere...
When last I was able to process film (my darkroom has been out of service for about eight years), I was using my own mix "Parodinal" made from acetaminophen, sodium sulfite, and sodium hydroxide...
I like the idea of that camera, especially the extension of putting a sleeve on it. Might be a good use of a small changing bag (too small for 8x10 film changing, more the size you'd unjam a 35 mm...
I've read, fairly recently (within the past year) an extensive web site by a woman in Oregon who is making her own ISO 25 orthochromatic emulsion, coating on glass and film. The tonality seems very...
Efke made the ortho film that's packaged as CMS20 (though I'm not sure they make the CMS20 II). This stuff is reputed to be originally a microfilm emulsion, but microfilm bears a suspicious...
I can make Parodinal for about a nickel per 8x10, Caffenol C for a few cents more, and D72 for printing for under a dollar per darkroom session with purchased metol and hydroquinone. Chemistry cost...
I've mixed Dektol stock solution in half the water and been able to keep the stock solution in glass pickle jars, with minimal airspace (but not topped up to zero airspace) for over a year. It still...
To my eye, the window light is just right -- there's plenty of illumination in the important shadowed areas, and still an interesting catch reflection in the glass.
Looks like a shipping container with the sun peeling a decal off the paint. Seems better than when I shoot stuff like this...
My experience with (35 mm) reversal processing indicates about a 1 to 1 1/3 stop increase in film speed, coupled with a great reduction in the visibility of grain -- effectively, the coarse grains...
Okay, here's another one. Homemade camera, started out as the core from a roll of paper for a photo printing machine (not sure what kind); I saw the lab tossing it, and asked to take it home. ...
This has been a long time...

Fomapan 100 9x12 cm, HC-110 Dilution G, shot in a Zeiss Ikon Ideal plate camera with a pinhole in place of the lens. I don't recall the hole size or...
Yes, that category. You can find less nice looking ones for as little as $10 plus shipping, in my experience (though it's been several years since I bought one). The Tessar (4 elements, 3 groups,...
I've seen formulae online for "diafine-like" two-bath developers. Seems to me there's been a good consensus that it's a P-Q speed increasing formula with neutral or very slightly acidic Bath A (to...
Wow, that resource didn't exist last time I looked at making my own film. I'll have to look through her site in more detail; it certainly seems as if, as long as we can get acetate and glass, we'll...
The most important handling rule for freezing and refreezing film is to avoid condensation conditions. Water on the sensitive surface of film (that's both sides, for most x-ray stocks) can remove or...
Ut oh.
Better Google around for the difference between a "Graflex" back or film holder, and a "Graphic" back. All modern 4x5 cameras have a Graphic back; the Graflex back went out of production...
Film choices are rather limited (one commercial offering at Freestyle, last I checked) but there are 9x12 cm "plate cameras" from the 1920s to 1930s era that give 85-90% of a 4x5 negative in a...
Sometimes the bottle is excessively alarmist, likely prompted by liability concerns (and lawyers). For instance, I recall a warning on the bottle of HC-110 concentrate that contaminated clothing...
A faster lens will make a difference here (that is, if the Sinar has an f/4.5 lens but the one on your Super is f/6.3, the Sinar will be about one stop brighter on the ground glass), but it's likely...
Toxicity is related to concentration. For instance, Alka-Seltzer is a solution of aspirin and various buffering agents; at the recommended dosage, it's therapeutic (for most folks; there are a few...
IF the damage is only to the coating, stripping the old coating will remove it, and the new coating will have (approximately) the same optical surface as the original. If the damage goes through...
The particles are most likely aluminum oxide: the stuff inside a firecracker that make the "bang!" is flash powder, usually aluminum powder with a strong oxidizer such as potassium perchlorate. If...
As a semi-educated guess, the double emulsion films use a grain technology appropriate for a single emulsion at half the speed (because the double layer gives roughly twice the density for a given...
If you like hand-held night photography without flash, this is the best solution available (that I know of) since FP-3000B was dumped in both 4x5 and 3x4 sizes. Here's a scan of the very first...
"Super Soup" is my own concoction, invented to try to save some of my early large format (9x12 cm) films that, on unloading from the film sheaths, I found had been loaded backward, hence exposed...
I first got my fingers in the Dektol in 1969, and I've used gloves only for one process: B&W reversal, in which I want to avoid contact with the sulfuric acid/potassium dichromate bleach solution...
