Hello Everyone, I'm still working on getting my first closet-darkroom prepared. I have 3 small trays that my father gave me from his old rig, and I'd like something bigger. It seems that the deeper 5" trays would be less likely to spill, especially when I make trips to the sink in the adjacent room. Are the deeper trays more difficult to work with for any reason when developing paper? Is there any advantage to the more shallow 3" trays? Thanks so much. I know it's a very basic question, but I have absolutely no darkroom experience and do not know anyone, other than my father, who has any to share. His only experiences are printing very small snapshots in his very small trays. Thanks most kindly for your patience with such a silly question.
