Here's what I'm gonna do:
Get some of those shop light things that hold like two long flourescent bulbs and build a little box to house them and then on top of that place a big sheet of glass about 6 or 7 inches from the lights and then hook the lights to a power strip so I can tun em on and off.
Then I'm gonna start burning screens in the privacy of my studio. The bulbs are gonna be "high output uv" bulbs. That's what I'm gonna do, and if this sounds wrong to someone, well please let me know what I should do instead. This is sort of based on all the stuff I could cobble together from various posts about building your own exposure unit and this seems like the cheapest way. Am I right?
