Anyone have experience developing 8mm film in caffenol?

  The size of the film doesn't matter, only the emulsion. This process is for B&W negative film emulsions. It will work okay with many other film emulsions, but the result will be a B&W negative.

  I've done a fair bit of developing with caffenol and beerol and a combination of the two on moviefilm, mostly 16mm but the process is the same. Volume of the developer is the issue. Works best in a bucket with 2 liters of developer per 400ft of material to prevent exhaustion. I personally like the combination of the traditional caffenol recipe combined with Dagie Brundert's beerol recipe. 1L of water (warm) 100g (20 tsp) washing soda 30g (6 tsp) vitamin C 60g (12 tsp) instant coffee 1L beer On something like Tri-X I'll use a dev time ranging from 15-20 min that I determine after testing. It's a nice balance in contrast between the two developers.

    Brilliant. 2 litres developer per 400ft of material seems a bit little though, no? > I personally like the combination of the traditional caffenol recipe combined with Dagie Brundert's beerol recipe. How comes, out of interest?

      For me beerol doesn't get to the density I'm looking for and caffenol, depending on a few factors, will result in a relatively high-contrast negative. The combined recipe is similar to a stock D-76 or ID-11 in terms of conventional developers. 200ft/L is a conservative estimate and I have been a part of workshops where we developed 1000ft per gallon, so YMMV. Checking my notes it looks like I processed reversal last time I did 4 rolls and so each roll would have been developed twice, essentially.
