<< I'll add that my exposure times for gum and cyanotype were so short at 1
1/2 inches above tightly ranked single and double fixtures (although
exposures were even) that I had to move paper stage higher.

Judy, please do write more on this. I posted a question about 1 or 2 months
ago asking whether I could use a light box for exposing my carbon tissue.
Your response (if I remember correctly) was that light box might not be
sufficient and one should use UV light. From that I had an impression that
you built your own light box, etc. etc. It seems like I was wrong. Do you
mean (in the above posting) that you just use regular double fixtures that
one can buy from a hardware store, and then just use UV tubes in them?
TIA!
