What ISO setting for expired 35mm film?

After I exposed my first roll of expired 35mm film, I learned that expired film should be overexposed by one step for each decade since the film expired. Good advice.

Last summer, a box filled with rolls of expired 35mm film arrived unexpectedly at my doorstep. Months earlier, I had contacted a college friend about the camera equipment she used at my wedding. Bhavna and I didn't have money for a photographer, and our friend Traci stepped in and offered her skills. I told her I was reshooting the film, and she mentioned that her mom had some expired rolls of 35mm film that she would send me.

Even though they were expired, I was delighted and couldn't wait to see what I could do with them. I catalogued each film stock, recording the type and the quantity. I have already used some of the expired film stock with varying results. After I exposed my first roll I learned that expired film should be overexposed by one step for each decade since the film expired. I updated the table in the original post to include a column for what ASA could be used for the expired film.

I am only guessing at the expiration dates using the year the film stock was discontinued as a guide.

Agfa Scala 200 1 200 50
Fujifilm Fujichrome Provia 400F 6 400 100

    Every stock is different, and how the stock was stored matters a lot in what ISO you choose. That's been my experience anyway. I've got a stash of Kodak Plus-X all from the same seller that I shoot at box because that's what works. With a large enough sample space I can shoot a couple rolls until I dial in the right ISO, and then shoot the rest that way.

    1. Hi Jim. Thanks for stopping by. I have enough of the Provia 400F, Velvia 100F and Kodak 200 to experiment. However, my XD-11 can’t shoot below ISO12 so my possibilities with low ISO film is more challenging. My result from expired Kodachrome 25 (developed as black and white) was disappointing.
