If this is an expired film, it is untested and no guarantees are given.

Our expired film can be bought in several options, this depends on the specific film.

Film with “no box” means that we could not save the outer package, due to its age.

Packages may look different than shown because the designs change through the years. Also, some may have a little bit of age to them as well. If you want a new-looking film you should buy a new film and not expired right?

Quick tip on using expired film.

Some film might be stored in a fridge and some might not, so shooting expired film is always a chance of luck.

Because the film is expired you should keep in mind you could adjust the ISO to its “new age”.
You know, have a little bit more sensitivity for it.
This should only be applied to color negative film, slide film is ofter better to shoot on “normal “box speed.

For every TEN YEARS, a roll of film is expired shoot it ONE-STOP LOWER.

So for example you are using a 400 ISO film from 2009.
You should shoot it one-stop lower so that would be?
200! Right on!
And now if it was a pack of expired film from 1999?
100! Again your right!

You could also first meter the scene and then lower your settings so you get one-stop lower.
