Holy hell, is that what DCG plates are supposed to like? Actually, come to think of it, I've never seen a coated plate in normal lighting. Actually I have, it was a plate that I had dropped and missed a piece, but I assumed the yellow colour was from light exposure. Huh... I'll have to check when I get home.
Dave, which DCG recipe do you personally use?
I'm also curious how using more dichromate affects the final transparency of the unexposed portions. I've seen holograms where the object is "floating", i.e., the unexposed parts are perfectly transparent whereas the object is very bright. I imagine these are taken using a black backdrop.
