From what you say >above it would seem that rating it at 1250 would give over-exposure. Each film will react to different developers in different ways. TMax P3200 is actually much closer to 1200 or 1600 in nominal speed, but performs so well with under exposure that at 3200 it looks great. And 6400 is like Tri-X at 1600. In actuality, Tri-X in HC-110 dil. B is more like ISO 200 or 250. But people shoot it at 400 because that's what the box says. No matter what film and/or developer you use you need to test it and adjust it until you get perfect negatives for the conditions you like to shoot in. It's not that hard, and you don't even need a densitometer to do it. You do have to be a pretty good printer and have a good idea what an ideal print should look like. You really need to try the developer that it was designed to be pushed in first, that would be TMax developer. Then try others in comparison to see if they do a better job. Don't try it with Press Maxx developer (golf ball sized grain) or HC-110. Horrible! (Any TMax film and HC-110 IMO stinks). ========== Eric Welch St. Joseph, MO http://www.ponyexpress.net/~ewelch Logic: The art of being wrong with confidence...
