I'm moving to a new apartment, currently, and my darkroom is quite temporary. I can't take the kitchen, or the bathroom. I just have a closet...
Pinned a black sheet to the doorframe, for day or night sheet film developing. In fact, I don't even have TABLES, yet. So there I am, sitting on the floor, rotating sheets of film in open trays... I don't have any electricity nearby, either, so I've been using diafine and my mechanical enlarger timer in 1-minute intervals (as long as it's 3 minutes, eh?)
Ridiculous, yes, but I can't just NOT do it! Crazy, what those chemicals do to you.
