You see it on the edges of your negs. Maybe with the sheetfilm setup this is minimized. With a Nikor tank with every inversion you give a slight twist and that is the way to develop black and white rollfilm taught in most good photo schools and done by the assistants of most photographers if not themselves. The sky is blue, the earth is brown. I could tell you your wife is ugly - but I'd never dream of putting down your *&^% Jobo's again. Mark Rabiner :)
