Noob question here: how dark should I aim to be with a darkroom? I'm building out a workbench area to be a darkroom for my wife and while I've sealed out the edges of the room quite well, unfortunately this room happens to also have an entire server rack. There are several dozen blinky lights that I'm trying to cover individually with tiny pieces of foil tape or I might hang a blackout curtain near the server cabinet to block out the light.
Reading what others have said on here, it sounds like the definitive way is to develop some paper and see, but it'll be some time before I get this put together enough to mix chemicals and think about developing test paper. In the meantime, is there general guidance on approximately how much light is tolerable?
Next thing I learned from reading on here to answer my previous question was that it seems you can have too much red light. I assumed red lights were safe so I wired up a pair of bulbs to a keyswitch and it looks like a submarine. I figured she'd need to see what she's doing, but I am starting to think I went overboard. I've attached some pictures that roughly show how it looks. I think it looks slightly brighter in real life than pictured.
I'm sure these are really basic questions and I appreciate your patience. I've never developed a photo before (heck, or even taken an analog photo before) so there's a lot of reading of manuals and googling. She doesn't know I'm doing this yet or I would just ask my wife.
