I guess I should stop what I'm doing and finally test my safelights now that I have both of them installed where I want them. I am using two simple Kodak screw in safelights with OC filters, mounted at least 48" from my enlarger base board and my developer tray. (I was to anxious to get printing after months of work to test them first!, and I seem to be getting pretty good results so far.) I've read numerous ways to test for safelight fogging. Some sound easy, some very laborious. What have some of you done to test your safelights? Would you recommend one method over another? Thanks.
