Okay, someone please explain to me (recently returned to developing) how to push film using Diafine, since time has no effect? Do you just shoot it at 1600 (or 1250) and the Diafine will automatically push it?
A film needs to be shot at the appropriate speed for development in Diafine. The Diafine packaging indicates that Tri-X should be shot at 1600, though many shoot it at 1250 or 1000 since Diafine does a good job of highlight preservation.
I think Diafine is a very easy way to get good results from Tri-X at 1600. No doubt other developers give you more control, but Diafine is almost idiot proof.
Finally, remember that Diafine doesn't demand critical temperature control. It's great in the summer when your chemicals might be 78/25 degrees at room temp.
