After being a long time Black and white printer and developer, i have decided to try my hand at color. I first decided it intolerable to allow careless stores to develop my film in some machine and then get them all dirty and ruined with their hands. So my question is, what are the components of a color developer? Can i mix one up from stock chemicals or should i just buy a premixed one? Is all i need for C-41 processing, a color developer, bleach, fixer (the same i use for my B and W?)?
