When I shoot roll film, I shoot Tri-X 400 -- I expose it at EI 200 and process in Rodinal. In sheet film, I've been shooting Bergger -- rate it at EI100 and process in Rodinal (1:25 for 6.5 minutes in a Jobo tank). I've wanted to try Tri-X sheets but have held off for a couple of reasons. First, I gather the TX 320 sheet emulsion is quite different from the TX 400 roll film. And second, I've found no recipes for processing it in Rodinal.

How different is the 320 sheet film from the 400 roll film? And why no Rodinal recipes? If someone could comment, and/or post their formula for process Tri-X 320 sheets in Rodinal, or explain why it's a bad idea, I would be grateful.

I am happy generally with the Bergger sheet film -- see www.mcnew.net for samples. Tri-X roll film gave starker images -- I'm not sure if that is attributable to the emulsion or the greater degree of enlargement required to make a print from roll film as opposed to a 4x5 sheet. Thoughts?
