Expired Ilfold Pan F Plus

[George Mann]

I have a roll of Pan F that expired in July of '22. It has not been refrigerated. Is it likely to still be good?

I dare say that if it is not "fried" at very high temperatures, this foil will be no different from new. I have 15-20 meters of PanF (no plus), from 1992 - it's amazing how well it has preserved, even though it has been at room temperature for many years. No base fog, and his speed has stayed very close to what it should be.

It'll be fine. Develop it promptly though as soon as you finish the roll.

How are frame numbers doing? They (being latent images for so long) do have a tendency to fade a bit in old Pan F.

Yes, the markings are pretty faint. It has been 30 years since the latent image was created.
I found the film in an old bulk loader. The year of the film was marked with a sticker - 1992. However, this is probably not the year of production of the film - probably the year the loader was loaded or the expiration date. That would make him even older. Also, this bulk loader has most likely been in someone's attic for the last 20 years. If it had been in the freezer the whole time, the marking would probably be in better condition. However, this film has retained its qualities admirably.

Absolutely. As good as new, even if it wasn't stored in the fridge. Film like this doesn't go bad easily.

The only risk is if it happens to be 120 film that you may have backing paper offset/mottling problems. With 35mm and sheet film this won't be an issue. (Has PanF+ been made in sheet film, actually?)
