I worked in a professional photo lab for 35 years and processed untold mega thousands or rolls of film.

If that film has been kept at room temperature for all those years a "fog" comes up from age. Normal C-41 negatives have a orange base color. The older the film is the less orange and more of a brown tone arises. I don't think the disc format came out in the C-22 film days so that will help your cause.

Finding someone to process disc film will be challenge one. We never processed it, as we did sheet film and roll film only. The negatives on the disc are just tiny, and a 4x6 inch print is about as big as you would ever want as anything bigger will be grainy. And the grain gets worse with age on undeveloped film.

Don't expect a good photo, anything close to what your cell phone shoots is way better. If you can find a place to process the film, maybe you can find someone to scan the negatives. Once it is digital, Photoshop can help a little.

We processed a lot of old film found in the back of a drawer at the grandparents houses of various customers. If it had been in the attic, it was almost always just a fogged useless image. If it was in the house and not over 20 years old, you might see a usable image, but don't bet on it. Even B&W film had the same fog issue.

Even at the best, the disc film made rather poor quality 4x6 prints.
