well, the title kinda explains it all. I'm nt looking to print pictures at home, however, I am looking to slash darkroom time by predeveloping my negatives at home and whatnot. Thigs for me to consider are cost (cheaper better), quantity (more better), and the fact that I will usually be using Ilford film and sometimes Tri-X. and just wondering, it ain't too hazardous to pour the developer/water mixture down my sink or toilet is it? We're renting, and leaving next year so pipe issues arent much of a consideration, however evil of me it may be.
