Greg, Thanks very much for taking the time to look into this aspect of the
glow

Hi:
Yes paper is pretty forgiving. Its not nearly as sensetive to light as
film. I rate paper at 6 ASA when I use it in a camera. My darkroom has a
couple of small light leaks around the door. I haven't bothered fixing
these yet. I will when I start processing real film. The CGP orhto film
and is a great demonstration if you are teaching.

I've been using a red party bulb from the grocery store
I've been using a red party bulb from the grocery store for about
10 years. You have to check around the base to make sure the red
coloring covers completely. I covered the gaps with opaque tape.
I've also used orange christmas tree lights. I haven't tried leaving
a piece of paper out for
10 matches
