Tri x has three layers does it not hence that's how they came up with the name? Plus x having one more which to me means two? Pan means one right? I may have thought that at one time. Or clear high tones like played with a flute? The films which have worked the best for me when I am in what I call "Ansel Adams mode" are the slow single layer films. Thin. Which is when I'm using my Hasselblad with the mirror locked up with a tripod and a cable release and the slowest film I can find with the high rez developer dilution combination I can find. When using even medium speed films many of which I'd assume had 2 layers it was never quite the same. Good old Panatomic x or Ilford Pan F. But tab grain films and Xtol leveled the playing field on that account pretty much. Like ACROS and delta 100. And Tmax 100 if you are not using Xtol. Or Rodinal. Ansel they say used tri x with his Hassy when he was in Ansel Adams mode. A mode he was good at. I never could get myself to have that "glow" and intense separation of all tones or anything resembling his work with 400 speed films. And lets not even bring up HC-110 I'm positive John Sexton when the lights were out switched it with Pyro. I've printed out their whole 22 page thing but so far it looks like a slower speed Tri x to me. I'd bet the fast larger grained emulsion was really a finer grained one but they added some chemical. And as I say I don't do well with thick skinned multiple emulsions. Mark Rabiner Photography Portland Oregon http://rabinergroup.com/
