How will I know whether I've overdeveloped or underdeveloped with Pyrocat-HD? I've never used a staining developer and I'm going to try my first negatives with it tomorrow. These negatives are something that I can repeat and probably will if tonight's negatives in D76 stock are anything to judge by. Is it best to only use the developer once? I'll be developing Tri-X 320 and Maco IR with it.
