I've just started developing my own film. I live in Tokyo so my chemicals are Fuji. The developer is Super Prodol in powder form. I decided to run a roll of Ilford HP5 Plus 400 through my newly acquired Mamiya Press. The problem is that Ilford's charts give development times for their own chemicals. Fuji charts don't mention film besides their own. Where can I find accurate info for this combination of film and chemicals?
