I used to just stand at the kitchen sink with a changing bag and two little plastic tanks. Did that for maybe 3 years. Then I visited a friend in Portland who had a whole setup with trays and a dedicated space. She showed me how much more control you get with a real darkroom tray for the developer stage. I tried it that same weekend with an old roll of Tri-X I had sitting around. The difference in grain and contrast was huge. Now I keep a tray and a small red light in the closet. Does anyone else find it harder to get consistent temps with a tray versus a tank?
