I know many of us have darkrooms that aren't dark enough for tray processing film. That's one of the reasons I went with a tank. Well while developing a print today an idea hit me. I'm working on a long table. It would seem putting a three sided box on the table open on just one side for access would turn my darkroom into dark enough for tray processing film. Light doesn't like going around corners so if the open side was away from small leaks I have then they shouldn't be a problem. A person could even put a clock/timer on top of the box and it wouldn't fog anything. If I ever get an 8x10 then I'll need a way to process the film. This sounds simple. Too simple?
