Hi everyone!
I've just joined, so want to say hello. My name is Roger, I live in Portland, OR, and I'm building a darkroom. I have a book or two that I'm going from, but I thought it would be nice to see if anyone has some reality-based experiences they could help me with. I've already learned, for example, to paint it white, not black. Glad I did before I started painting!
I'm building in a single-room outbuilding that's about 10' x 14'. The back 10' will be darkroom with the front 4' being workspace (home office) and entry area, and therefore lit and not light-tight. I had designed a traditional U-shaped light trap for entering/exiting the darkroom area, but now I'm wondering if this is too much of a waste of space for the advantages gained. I do not want to use a revolving door because of expense and the fact that I will need to move large objects in and out (the sink, print washers, etc.).
Would I be better off just using a door and hanging a curtain over it? This would mean that every time I wanted to step out to check something in the light I'd have to close everything up and finish make sure all prints were in the fixer before opening the door. With the light trap approach I can step in and out at will without worrying about it. Any opinions?
Also, I'm wanting to install a fan. The outer walls are only 2x4's and there is no ceiling space, so there is only a three inch space in the outside walls. I would like a simple through-the-wall fan with a light-tight louver, but I can't find any that would fit within a three inch wall space. It would also be very hard to use any that required ducting, as ventilation ducting is usually at least 4" and I don't have that much room. I have read some suggestions on here by people that just open the door and run a floor fan every 1/2 hour or so, and I suppose I could do that if worse came to worse, but as I am building this darkroom from scratch (not adapting another room) I'd like to make it as robust and nice as possible, since I have the opportunity and can do anything I want, pretty much. On solution would be a simple louvered vent in the wall that would be exhausted from the positive pressure of the air conditioner/fan that I have installed in the front office portion. But then I'm concerned about air leak. Since it's a small space not heated/cooled by any other area (as a bathroom in a house would be, for example) how do I stop cold air from blasting in through the exhaust system in the winter?
If anyone has experience dealing with these issues I'd be very interesting in hearing any advice. Thanks!
