From browsing the forum, it seems that the skilled people here have ways of judging the success of their negative development besides printing (or scanning). I read about negative density but have not read anyway that this is measured. Can someone explain this in a bit more detail? Now that I look at my two rolls of film developed, I think that they might be a bit "thin", but really am not sure. I have to wait 1 more week to get scans done. I can neither print or scan them at home, so am not certain of my success. I'm going to do one more roll tomorrow, and then await the results. I'm wondering about what negative density is and how it is measured so that in future, I can judge my results more methodically then just eyeballing them.
