What is the difference between expired and non-expired film?

Hi, my friend just told me to buy his expired film for few cent cheaper than the original. What is the difference between expired and non-expired film in term of quality, sharpness, color, (technical)?





Thank you|||Basically, the only difference is the date. There's no real way to date film if it's kept cool (like in a refrigerator, for example), expired film can still be used and produce the same results as new film for a long time. So long as it is kept in a cool, relatively dry environment, expired film will have no loss in quality, sharpness, or color. Camera shops that sell expired film, if you go to a good one, keep their film in a good environment for keeping fresh, but they can't call it fresh and sell it as fresh because it's out of date, so they discount it. And it's great. I buy expired film all the time. You never quite find the brand and speeds you may be looking for, but it's a good buy. Put it in the fridge until you can use it - or use it. Either way, you'll get identical results (to non-expired film), 90% of the time.|||Film has a date of which it is no longer guaranteed to be be fresh and as the manufacturer describes. I've never really noticed much of a difference between film that is past the date and what isn't. I even have some old black and white sheet film around here that is about 30 years past its expiration date. It has a "fogging" to it but I use it from time to time to test lenses, developer, etc.





For pro work of course I would use only fresh film.





But for just a few cents difference buy the fresh.
