Annie, you can have something similar if you are good at making things, or perhaps a freind can build a light box for you. The plans for a light box are at the edwards engineering web site. Of course you can buyone of theirs, but they are expensive.

You can also look for plate makers in E bay. look for the Nu Arc 26-1k. The can go anywhere from $300 to $500 plus shipping, and the shipping will be another couple of hundred dollars. Many of us are using this units as they have a light integrator and allow you to burn or dodge if you need to do so.
