My teacher at the academy asked me to do a class on 'b/w development' (it's all digital), as I am one of the few ones that work analog mostly. Just very basic class, but the idea is to motivate other students to either start with analog photography and the ones that already work analog; motivate them to start developing the film themselves. I am wondering if I have the 'main' variables straight here in b/w film development that will influence the result, I know, very subjective and much more to tell, but I want to keep it very simple, so here they are: - Developer/dilution. - Development time. - Agitation. - Temperature. Any thoughts anyone?
