Since I've started shooting in the early 90's I've always kept my my negatives stored in Print File type sleeves. I've always wondered about the longevity of my negatives when stored this way, since some of my earlier sleeves have started to show their age. The negatives seem fine inside, but honestly I have negatives in there that have not been out of the sleeves since I put them in there in 1992.
Since I picked up my first 4x5 last month, a Cambo (and since then a Horseman L45, yes I know LF is addicting) I've been wondering if I should go the route of using the plastic Print File sleeves or use the Print File 4x5 envelopes and store them in the old film boxes. Right now they are being carefully kept in an old film box. If it matters all of my negatives are kept in a safe deposit box at my bank.
Whats says you?
