Response to the minimum amount of D-76 needed

If you want to be completely safe, you can follow the guidelines in Anchell and Troop's _The Film Development Cookbook. They recommend 250ml. of the stock solution per 8x10=1roll120=36exp.of 35mm.=4 sheets 4x5. So, if you dilute the D-76, use a bigger tank. I believe that Kodak says that you need a minimum of 100ml. stock. I've done it both ways, and have done OK. When in doubt, I tend to go with the larger amount; might as well use up the D-76 while it's fresh. I just looked in the Kodak B&W Darkroom Dataguide and didn't find dilute sheet film times, either. Someone should jump in with theat. In any case, if you don't have the Anchell and Troop book, I think it's a "must study." If you do, you know that they have really worked it out!
