I would be curious to know what methods forum photographers use in identifying, noting, marking, etc. their film holders from one another--those that might need Normal, Plus develop, Minus develop, etc . Are your holders "marked" in advance of the shoot? If marked, with what? Are they "marked" after the shoot? When you get into the darkroom to process your film take, how do you identify those film holders which need N,P,Minus development?

Thank you-Raymond
