Can anybody point me to a chart for reciprocity failure for Kodak Tmax & Tri-X films? The Kodak film book only covers metered times of 100 seconds and less. I realize I'm going to have to run tests, but was wondering if there is a good set of starting points for the longer times. Also: how do filters alter the equation, in general?

Does anybody have any comments about the Arista sheet film sold cheap (37$/100 4x5) by Freestyle? I am a beginner and so am too clumsy with development and too unpracticed with exposure to make any definitive judgments about it, but I'm on a very limited income and the low price makes it quite attractive to me. On the other hand, I don't want to be pound foolish, either, and chase after problems or unsatisfactory images that are the result of the film and not my own novice mistakes. So far it seems to be working, though.

Gawd, I spent nearly three months loading all my film backwards when I got my camera. It drove me absolutely nuts trying to figure out why my film was so underexposed - never occured to me the film notches are supposed to be on the top right HORIZONTAL edge; I was loading it with the notch on the "top" right vertical edge - which is backwards. Finally I took my film in the holders to my father, experienced in sheet film from press camera days, and he had a long hearty laugh at my expense. I feel better somebody else had this problem too!!
