I've just had what I consider great success with Caffenol-C-M (Reinhold's formula) with both Fomapan 100 (Arista Edu Ultra) in 120 size and Kodak BW400CN in 35mm. I exposed both at ISO 200. The former film is one of Reihold's favorites and the other is one of Steveh Schaub's preferred films (Figital Revolution). I mixed one 500ml batch, and first developed the 400CN in a single roll tank with 260ml of developer for 15 minutes, then double stopped, first with water to get rid of the residual brown developer, then with Kodak indicator stop bath, both for 1 minute. I then fixed for 5 minutes in Arista fixer, followed by the rinse and Photo Flow process recently described by Roger H. I was a bit taken aback by the negs. The images were clear, but very dark and dense, but the spaces between frames were OK.

After I developed the first roll I dumped the developer back into the half-full origninal graduate, stirred it a couple of times and let it set while I fixed and rinsed the first roll. That done and hanging to dry, I poured 475ml of the developer into a double roll tank holding the roll of 120 Fomapan, then repeated the whole process and hung it to dry alongside the first roll. I let them dry all last night, then cut and sleved them this AM.

Intersperced among other tasks I've been scanning them images all day--yes it does take a while. The 35s I scanned on my old reliable Microtek Artixscan 4000t @4000 dpi. I used VueScan on 48 bit color using the Kodak Gold preset. Resulting images were 115.5 Megs! This roll I shot in my Contax G2 w/45mm/2.0. The roll of 120 I shot in my Fuji GA645zi. I scanned the images on my Epson 4490, using VueScan @2400 dpi, 16 bit grayscale. Images were about 35.5 megs. The first image is from the Fuji, the second from the G2.

These shots were taken at a rural church cemetery near my home.

Congratulations and nice photos!

I'm also experimenting with Caffenol C-M and Arista EDU Ultra 100 in both 35mm and 120. I'm curious, did you use Reinhold's weight (gram) or volume (milliliter) measurements? I ask, because I've tried both, and measuring the coffee by weight (with my particular coffee) requires way, way more than by volume, which is somewhat confusing to me. Perhaps the coffee I'm using just has more air! At any rate, I'd be interested in others' experiences; I haven't had a chance to ask Reinhold his opinion yet, but it definitely changes the cost/roll for me if I measure by weight.

Thanks,
Duane

I use Reinhold's measured weights, rather than Steven Schaub's measures. I also do cartridge reloading, and I like the concept of repeatable weights, then I can see what other variables to try. I got my ascorbic acid from Photographeer's Formulary and need to order more. I used Reinhold's suggested 15 minute developing time, and standard number of inversions, 10 at first, then 3 per minute. Next time I think I'll expose the Fomapan at 160 and the 400CN at 320 as the former seemed a bit underexposed and the other a bit over. I scanned each as DNGs and they were easy to work with in Adobe Bridge Raw. This was my first experience with the Fomapan 100 and it really looks great in 6x4.5. I've got more in 35mm that I'm going to run through the G2 and see how it looks. I think it would print nicely on Epson enhanced matte paper. We'll have to find out. BTW, I have had similarly good experience with Fuji Acros 100 and TMax 100 in this soup, both @ ISO 200.
 
Just as heads up for anyone wanting to try Caffenol-C-M with Rollei Retro 100: I've now given this a go, three films, one exposed at ISO 100, one at ISO 200 and one at ISO 400. All developed with Reinhold's formula, 15 minutes at 20 Celsius. Works really well at ISO 200:

Randomm: I really like those tones. I've just gotten a batch of Fuji Across 100 to shoot in 35 and 120, and have ordered some Arista Edu Ultra (Fomapan) in 120 in both 100 and 200 to play with. It will be my first time with the 200 and I'll post results in a couple weeks.
