i'm about to venture into the world of paper negatives(from pinhole cameras). i have a few questions about the paper chemicals. i've bought ilford paper chems for development, stop and fixing. they are all in liquid form, so it looks like i can just mix as much as i need as i go along(very much like with chemicals for film). can the chemicals be reused? when i develop film i routinely re-use the fix, but nothing else. what about for paper - fix? developer? if so do the chemicals need to be stored in dark/opaque bottles?
