Bergger Pancro 400 Vs Tri-X 320?

[Arklatexian]

FWIW (not much): I've tried a few rounds with Bergger film. I would like the fact that Bergger is available in 5X7 as a normal stock; however, it seems routinely out-of-stock in the more economical quantities,. Like their Berspeed developer much better on a Jobo processor. Now more focused on FP4+ and Delta400, but may have another go at HP5, too. New copy of Developer Cookbook likens current TRI-X more to Plus-X, but I don't think TRI-X 320 is the same animal.

I have always been told and read that TX 320 and Tri-X are two different emulsions. Also that TX 320 is grainer (but not "grainy") and this has been true for many years. That made sense to me. Why make two different films if their emulsions and speeds are the same? As I remember, 320 TX was being made before the 400 TX came along.............Regards!

TXP was a very different film to TX, their curves showed how different at a glance. TXP used to be a very popular film for controlled lighting type photography, I tried a few rolls many years ago for outdoors work and didn’t care for it but I admit I didn’t mess around with development times, I think I got the dev times from AA’s book The Negative.
