Tri X is good stuff – it’s pretty hard to not get a usable image out of it normally, it’s got very wide exposure latitude. On the other hand it’s got a bit more grain than more modern films like Tmax or Ilford Delta. The exact look of the results are going to depend on your developer, though. I’ve used it with Diafine:
Tri-x to me is the classic looking black and white film. Very forgiving of exposure error, you can underexpose the roll one stop and not need to push stop it. I’ve shot it at EI1600 with decent results. I will usually use D-76 developer with it either full strenght or mixed 1:1 with water (ie 4oz d-76 mix and 4oz water) which gives a bit finer grain.
