Ilford Pan F+ (improved over the old Pan F) is available in medium format. Pan F+ is not available in sheet film, probably because FP4+ has a fine enough grain structure for large format, and the extra speed for depth of field is often required. Both of these are excellent films, and much better than Panatomic-X in my opinion. I use Rodinal in dilutions of 1:50 to 1:100 (1:50 for low contrast scenes only) for both films. Most other developers also work well with these films.(posted 8238 days ago)For "artistic" photography, I prefer these “conventional” films over the T-Grain (Kodak TMAX and Ilford Delta) films, but I am sure that others have different opinions on this subject. As Conrad mentioned above, Anchell & Troop explain the differences between conventional films and T-Grain films in their book, “The Film Developing Cookbook.” Don’t be put off by the title; it’s a great book to have even if you never mix your own developers from scratch.
