Hi all! I sure have learned alot from reading the various threads but I'm curious to know if there is a good book on the subject of chemistry in general? Something that will provide answers about how long chemistry will last, storage, Pyro vs. Rodinal vs. D76, etc. I'm fairly new to darkroom work but I want to learn more. Would the "Darkroom Cookbook" be a good choice? Suggestions? Thanks in advance everyone!
