The book that Paul Harris refers you to is excellent. As for developers, I would encourage you to try Xtol, which I am very impressed with. Dilutions of 1+2 and 1+3 are very good. It has given better results than Microdol-X which I used in 1+3 for years, and better than my memory of D-76 from years ago. --Sam Elkind(posted 8859 days ago)
