Tech pan is the clear winner in the grain wars. However for enlargement to 8x10's APX 25 or Ilford pan F will work fine. In fact for 8x10's, t-max 100 might fill the bill better than Pan F according to my testing. It just depends on what you mean by fine-grained. At 11x14 size (~11-12X enlargements), tech pan will start emerging from the others. Keep your negatives on the thin side to reduce grain.(posted 9049 days ago)To try the ultimate, get a couple of rolls of Tech Pan 2415 and a box of Technidol liquid developer. Shoot one roll at an E.I of 25 and develop as directed on the liquid technidol box (expecially the agitation routine), except I've not found the need to drop the film reel into the full tank as recommended. Evalute the results and then shoot the second roll. Enjoy!
