Yes—there’s a reasonable chance of recovery. The common approach is to rehydrate the roll and gently separate it in darkness.

Start by placing the roll in a light-tight developing tank and filling it with plain water around 68–72°F (20–22°C). Agitate for about a minute, then replace the water. Repeat several water changes during the first hour. After soaking, check in complete darkness to see whether the film begins to loosen from the backing paper.

If it’s still stuck, continue soaking longer. Some labs have had success with several hours of soaking. If plain water isn’t enough, try a Photo-Flo solution mixed as for film processing, or add a few drops of mild dishwashing liquid to the soak water to reduce sticking. Check periodically and handle very gently.

As a last resort, the Photo-Flo bath can be warmed gradually—roughly up to 90–110°F (32–43°C)—while monitoring carefully.

Key points: keep everything dark until the film is on the reel or ready for processing, avoid force, and expect that some damage may remain. But soaking and patient separation is the standard recovery method for wet roll film.
