I've searched around on this and haven't found a lot of information. Is it unheard of? Crazy? No benefit? Microscopic ice crystals forming and splitting film? It seems that if we can store unexposed and exposed-but-unprocessed film in the freezer that we should also be able to store negatives in the freezer as well. I'm thinking about archival boxes where things are relatively easy to seal and one probably won't be pulling them out at will. More recent negs being worked on are of course left out. Would this offer greater archival benefits than room temperature storage?
