I'm going to buy my stuff soon, but I still have some questions. I remember I saw T-Max developer at my local photo store....is that required for T-Max films ? Basically I mean if you can develop all b&w films with the same chemicals, or do kodak, fuji, etc all need their own stuff ? Also, with shooting monochrome film (which is c41) can I develop that too in b&w ? Cause if it doesn't I'll have to buy normal b&w film instead of the kodak portra c41. And third, how on earth do you keep your chemicals on a specific temperature ? I read in a guide that some stuff has to be 'exact' 20 Celcius, while the other can be one or two degrees off. Well, I don't see anyway to be right on 20 C. Thanks =)
