Re: Dichromate dilution and speed

hi everyone, just to go a little off topic - re pigment ratio, does the
transparency of pigment have anything to do with exposure time? It seems
logical to me that the more opaque the pigment, the longer exposure but I'm
a little jet-lagged so perhaps I'm not that logical.

The "Print Exposed" exhibition was lovely - first time I'd ever seen a lot
of the techniques and certainly the first time I'd ever seen so many alt-pro
people together in one place!
