I am in final stages of completing my own darkroom. This space will be used by two photographers ALOT as well as the occasional friend. I have been using school facilities for some time... I am adept at mixing school chemicals (D76 and other basics) as well as using some Tmax dev. for Tmax film.... Thats about it. I own the "Darkroom Cookbook" and this place seems to be a great resource but chemcals are just a little intimidating to me. I'm torn between keeping things simple and experimenting with all kinds of stuff. I'd like to mix my own stuff as opposed to buying mixes. Is there a good developer that can be standardized easily and maybe tweaked here and there, to do other things? What are good, easy Stops and Fixes? Anyone have any advice on the matter?
