I've shot Tri-X rolls @400, 800 and 1600, Delta 3200 @ 3200 and 1600 and I'm currently doing the same with Tmax 400 @ 400, 800 & 1600
the last roll (TMY 400 @ 1600) is currently loaded in the Bessa III so I'll be able to do comparisons (based on my way of shooting)
Currently my tastes are :
1°) Delta 3200 @ 1600 (by far)
2°) TMY 400 @ 400
3°) TMX 400 @ 400
4°) TMY @ 800
5°) TMX @ 800
6°) Delta @ 3200
7°) TMX @ 1600. (I've got poor results, developped by a reference lab here in Paris). John just demonstrated that correctly exposed @ souped he got wonderful results.
