This is Tri-X, with Rodinal 1-100 stand developing. Really just experimenting with it (and some Ilford FP4) because it's what I have on hand right now as I spend a bit of time with film.
I picked Rodinal just because of its long life and ease of using it in stand processing.
I know the grain is pretty pronounced and may not appeal to all. After spending the past few years exclusively in digital, I sort of enjoy the grain. If I keep with it, I'm sure I'll try some other combos as well.

Tim, what film are you using on this and are you pushing t it? You should try some shots with tmax. it has great tonal range and i find it works well for portraits.
