I am preparing my long awaited darkroom. When we moved to a new home I had a 15'x16' room built with plumbing for a sink. The room is accessed from my utility room so I have a baffle of sorts from the outside light. The room is nice and dark with no need for door or window blocking. As the room is a good size and out of the way, I put my TV/Internet modem in there too. You guessed it, green LED lights. Covering these would not be difficult, but should I? Will such small green lights cause problems with printing?
