I'm working with old Kodak transtar paper for lith, and I've got a lifetime supply of it. The prints look best on my light box, I imagine the same way a big color transparency does. Had some thoughts of building boxes for my big prints, but tubes put out UV and bulbs put out heat. Now I'm playing around with LED's, and they seem like the perfect light source for a project like this. Anybody know anybody who is doing this? Re-inventing the wheel can be fun and rewarding, but I just finished my darkroom and six months of that took the wind out of me when it comes to problem solving.
