I'm thinking about getting some tech-pan 25 film and technidol developer for some pictorial photos. anyone used this combo before? I've been using tri-x 400 and d-76 developer (or its arista counterpart actually) so i'm expecting a pretty drastic change in contrast, tonality seperation, and grain amount. I have some microdol-x developer and some pretty fine-grained 100 speed film (agfa apx 100 pro, fuji fp4+) now to try, as well as a roll of fuji pan-f plus (iso 50). Any suggestions? Any major differences I should know about when shooting this type of film except for the traditional "expose for shadows, develop for highlights" bit?
