Since learning to develop film by inspection, I have been doing a lot of it. I h ave also heard and noticed both that in past years, Fred Archer and AA started w orking on the Zone System about the time a lot of the inspection development was going by the way. Does anyone have any historical references, articles or whate ver on this change in development methods. If one develops by inspection all you really need is solid shadow exposure and p ossibly an indication of where highlights might need to fall as a help in initia l planning of the development...a rough guide as to maybe giving a bit more or l ess development, the final decision being made as you view the negs under the gr een safelight. If you do this, the constant zoning, testing and obsession with m inute changes seem to go out the door. Time is approxiate til turning on the saf elight & seeing your negatives density. Temperature really doesn't matter, other than being in the ballpark. Developer aging isn't much of a factor either. Deve lop, look & see, and put the negs in the stop & then finish up. So, anyone out there know of information sources on inspection and Zone system d evelopment?
