Re: Lighting for Platinum/palladium Alt proc Work Area
I taught "alt" for 14 years in a lab with only fluorescent lights in the ceiling... never saw anything like a problem from that, tho the ceiling was about 10 feet up. (And we hung to dry in a closet.)
I also a couple of times tried to expose "through the back" of a print on a UV table.... after maybe 4 hours about 2 inches above the bulbs, there was NOTHING, NADA ! visible from the "exposure."
I do conclude, however, from various tests, that dry emulsions are more sensitive than wet. Which is to say, I always dry in the dark... with an electric fan, but no heat. (Doesn't everybody?)
