Hi all, I've set up a darkroom in the basement of our house, sharing a room with a washing machine (no, it cannot be used for drum processing. The household public opinion is not in favour). When using the room as a darkroom, I board up the window - at all other times, daylight flows in. This leads me to wonder about how to store my chemicals - how much deteoriation will exposure to daylight cause? What I have is an assortment of - Plastic bottles containing non-diluted developer, fixer, selenium toner - Clear or brown glass bottles containing dilutions of the above - Clear or brown bottles with stock solutions made from dry powder (D76, Xtol, Calbe fixer) - Bags of dry powder (most are light tight it seems, so perhaps not an issue). Would it be a good idea to store it all away in a light tight box outside darkroom hours, or does daylight not influence storage life? Thanks!
