After trying to coax Tri-X to work for me, I gave up and switched to HP5+. With my developing procedure, I've got finer grain and a longer tonal scale with HP5+ than with Tri-X. I also find working with HP5+ much easier than working with Tri-X.(posted 8717 days ago)I expose HP5+ at E.I.200 and develop it in HC-110 diluted 1:60, or expose it at E.I.400 and use HC-110 dil-B or D76 1:1. D76 1:1 does wonders for this film, but I moved to HC-110 simply for convenience, and the results are comparable. HC-110 diluted 1:60 gives me a tiny bit more sharpness and acutance with HP5+, and also acts as a compensating developer. Off late, I've started liking this look.
I once tried Rodinal 1:50 with HP5+, Tri-X and APX400, but, as expected, the grain was huge and distracting.
