I've heard that some chemicals (toner?) will fog paper that is stored in close proximity. Does anyone have a definitive list of the problematic ones? I need to do some cupboard-consolidation and it'd be nice if I could store paper in a darkroom cupboard. I have B&W and RA4 paper, plus: - rapid fixer in working and concentrate form - glacial acetic (messy bottle) - concentrated multigrade (messy bottle) - sealed dry stuff (xtol, d76, etc) - sealed conc devs (rodinal, HC110) - Xtol in a Mylar bag/box, D76 in PET - C41, RA4 and E6 kits as working solution (PET bottles) & concentrates (little glass bottles) I am pondering getting Selenium and Sepia toners maybe next year, presumably that means I'll have some more bleaches too.
