B&W film inspection

Funny... No sooner had this thread popped up, I find a Kodak #3 green safelight in our school darkroom...

And Doremus Scudder found the graph, I was wrong - it lets less green than I thought… about 1/630th of the green gets through.

Also I found the siamese cat, it’s in the filters guide.

Note: the siamese cats show how fog ruins prints. When you fog a negative, you can correct for it when you print, fog doesn’t ruin a negative as secerely as it destroys a print.

And, if you use pyro style developers the emulsion hardens as it developers which will make it even less sensitive to the green light.

That's not true at all as I do this on a regular basis using Pyro. Funny how this post goes round and round....try the old Fred picker axiom
TRY IT!!

I have tried it with several different pyro developers and never had any issue with the green light affecting my film. As a matter of fact, at one point I had a 10x12" safelight with the requisite green filter mounted directly behind the developer tray and short bursts of light toward the end of development was no problem.
