How do you know if film is expired?

How much does it cost to get 35mm film developed?

The stores charge from $10 to $15 for a 35mm roll, depending on the number of exposures. That price includes 4 x 6-inch prints and a CD with fairly small scans (a Walgreens worker told us the scans could be blown up to 4 x 6 inches). Walmart offers similar services, with prices starting at $8 for a 12-exposure roll.

Can you use film after it expires?

It’s more of a “best if used by” date.

You should get it developed before the film expiry date. It will develop if left longer but the colour will be off. Now if it was black and white film you could leave it in there for 50 years and it would be fine.

Should you overexpose expired film?

There’s a rule that states that a film loses one stop of its speed after a decade of expiry. So, if you’re lucky to own a film with 10-20 years of expiry, apply this rule. At every 10 years, overexpose by one stop. If it’s ISO 400, after 10 years will be ISO 200.

How long can film last before being developed?

Film should really be developed within a year of being exposed. After 2 years to 5 years, it might get a little grainy, and the colors might shift/fade a little bit.
