I'm with Scott. Have been using Diafine/Tri-x @800. Negs in 35mm and 120 are very, very sharp, excellent contrast, and really decent grain. An ei of 1200 would probably be a little better with this film as sometimes I find it necessary to print with a grade 1 filter. Definitely worth a try if you haven't used it already.(posted 8063 days ago)JIM
