Johnathan Russell commented on the differences in toning VD prints, and the
apparent effect of the light sources. Just as an observation, I have noticed
that the platinum and platinum/palladium prints, as well as cyanotypes, all
seem tobe "crisper", for lack of a better term, when exposed via sunlight vs
a uv light box. This is the old point-source vs diffused light situation, I
would guess.
Might be this has some effect on the toning as well, although I would be more
suspicious of electromagnet emmissions effects affecting toning (boy, is that
a mouthfull!).
