10 Year Past Expired Dated Astia "Experiement": Storage Conditions Matter
I bought ~ 200 sheets of expired 2003 dated 4x5 Fuji Astia transparency film sitting in bin at Calumet back in 2003. Took it home and refridgerated/froze ithem. In 2009 loaded some of these sheets in film holder, but never got round to them and left the film holders at room temp in hot S. Caifornia apt witout air cond for another 3 years. I finally shot those "room temp" sheets last year: they showed serious fogging/heat damage.
Meanwhile from same 2003 expiry batch that I kept mostly frozen but sometimes refridgerated, loaded 8 fresh sheets from freezer and sealed metal foil Fuji packaging this weekend: They showed no ill effects - colors came out great. So this gives me confidence on the other expired color film and the color films I stockpiled.
Apologies for not having the scans... Have to get and Epson V700 one of these days.
