I have an alcove which I plan to convert into a darkroom. It has a pretty good setup for one already. There's a counter along one wall with a sink at one end, and I'm going to set up another counter on the opposite wall for my dry space. The problem is that there's no real door to the alcove, just an archway with a roll down (and definitely not lightproof) wooden shutter-type thing (I can't think how else to describe it). I've browsed through these forums and found the suggestion of using thick black fabric to seal off light (as well as several other suggestions if that doesn't work), but that was pertaining to sealing off windows, and I have a whole doorway which I have to be able to get through when I'm done working. So here's what I was thinking, and I was wondering if someone with more experience doing this would let me know if it sounds like a good idea: I was thinking of covering the wooden shutters (which go all the way to the ground and overlap the wall on either side of the doorway) in a lightproof material, that way if I bump into the door on accident light won't flood in. Then, since light might get in through the edges, I was thinking of hanging another layer of the material on the other side of the doorway. With that setup I should be able to roll up the material and let the room air out when I'm not using it. But since both layers would be just hanging there, not really secured, I'm not sure it's enough. Should I maybe put a strip of velcro along the doorway to keep the fabric in place? If the fabric is on the long side and hangs on the ground, do I still have to worry about a light leak at the bottom of the doorway? Sorry for the long post, but I want to have a good idea whether or not this will work before I go and spend money and time rigging it up. If anyone has another suggestion of how I might do this, that would be helpful as well, as long as it's not terribly expensive or intrusive to set up (the alcove is attached to the family livingroom and I don't want to make it into a construction zone while I'm doing this). Thanks for reading through that, any advice or input would be greatly appreciated.
