   This is a puzzler. I don't think the support softens up much when soaked. It may be possible to straiten the film by soaking it in a hardening bath to keep the emulsion from softening up too much and then seeing if the support can be made flat. It may be possible print from the wet film or even to scan it. If the support is badly bent it may become distorted at the bend which will cause some refraction there, a light or dark line. If a single frame it may be possible to detach the emulsion and float it onto a new support, a piece of glass perhaps. This is a trick used to restore broken glass plates. I don't remember the details of how its done.

I'm wondering if a film scanner that feeds from the sprockets could get the film flat enough.  My flat bed with its holder I am sure wouldn't.  Got two labs that might be able to do it.  Anyone recognize 3LIM or 31IM?  It is a safety film, which might mean this film could have been processed under a safe light.  My search has turned up nothing.  Just knowing that might be an important piece of information.

I'd try this in my Nikon LS-9000 glass holder if I had the neg.
