I know this question comes up occasionally, but I'd like to hear some opinions unique to this situation. I've got several binders of modern medium format Provia and Velvia slides that have been shot recently along with a vintage collection that includes Kodachrome slides and a number of early Ektachromes (1950s) that have some how managed to keep from fading (and I want to keep them that way). I was thinking of putting the whole group in a large rubbermaid bin with some silica packs and keep them all in the fridge. RH is 35-50% at around 7C, which meets the Fuji long term storage suggested conditions. Otherwise they'd be stored in a room that is usually 45-50 RH and 17-22C. Does anyone have any experience with refrigerated storage? Am I taking this a bit too far?
