The late Fred Picker actually recommended that all 35 mm film should be targeted to print on Grade 3 paper. His reasoning, which seems valid to me, was that this would involve less development time for the 35 mm negative. He felt that this would lead to a somewhat less grainy negative and that the 35 mm negative needed all of the help it could get. While it has been a number of years since I shot any 35 mm film, I wonder if my medium format would not benefit from the same reasoning. I have not shot any medium format for a long time. I think that if and when I pick that format up again that I will develop my film accordingly.
