I tried a number of Caffenol prints today and noticed a lot of stain creeping in from the edges of the print. My darkroom was quite cold, and processing times were very long. Perhaps that is part of the problem.
My process is: Develop, water rinse (so that the Caffenol doesn't make my stop bath go all funky), stop, fix, first wash, tone in selenium, wash (in Ilford Wash Aid), final wash.
If anyone has experience in printing with Caffenol, I would love to hear your opinions.
