I use out of date films quite a bit for various projects, the majority of it is chrome film, with the exception of maybe two or three rolls over the years, I have never had any color shift problems and such, I currently have about a dozen bulk rolls of velvia 50 in the freezer and the first few 36 exposure rolls I have loaded and had processed have came out fine with no problems, and the bulk I am loading from right now expired in 1997, the key is, has it been properly stored? So far the films I have purchased off ebay have not been bad.
