Response to how to evalulateand compare negatives

Hi, Just a short note to make you aware of another source for information about non-densitometer testing. The paper-based method described in the book "The Zone System Manual", by Minor White, Richard Zakia et al is one that I have used successfully for years now. It describes how to make Zone System tests for film speeds and all develpment options and requires nothing more than your negative, enlarger and paper, and, it's scientific!! Check it out. Regards, ;^D)
