> To keep things on topic, I've played a bit with Caffenol and found it to work reasonably well but lost something like 1-1/2 stops speed (varied by film type) and the stain seemed to be an overall cast, not proportional like you get with pyro.  Only a little bit of inspection with a densitometer, nothing exhaustive and none of it terribly scientific.  Just piddling about a few years ago because it sounded interesting.

I should clarify, the 1-1/2 stop loss was the coffee-only formula, no Vitamin-C added.
