Frame-A-Day Tech Notes

I've got a Canon AE-1, loaded with Kodak Tri-X film and equipped with a 24mm lens set aside for this project.

Tri-X is normally rated at ISO 400, but after reading about how far that film can be pushed, I thought I'd give it a whirl myself. So, I'm rating it at 3200 (that's 3 stops underexposed).

I'm developing it in Rodinal, diluted to 1:100, using semi-stand development; that is, pouring the developer into the tank and letting the film sit there for 120 minutes (that's the 'stand' part). I do slowly invert the tank once every 30 minutes, otherwise I tend to get uneven development across the negative (the 'semi-' part).

The negatives come out of the soup looking rather thin, but my scanner can pull a surprising amount of detail out of them.
