Is film ruined once exposed to light?

If too much light hits film, an image will still be produced on a negative. An overexposed negative, even 3 to 4 stops over, can then be corrected in scanning or printing. Film captures images with a photochemical reaction in the emulsion when exposed to light.

What happens when your film is exposed to light?

Photographic film consists of a thin layer of silver bromide coated on a celluloid strip. When the film is exposed to light, the silver bromide is converted to elemental silver. This image is then chemically amplified to produce a negative when the film is developed.

What happens if you open a film camera mid roll?

As film passes the gate, it is rolled up inside the camera. In most modern 35mm cameras, this roll of exposed film is contained only within the camera. As a result, when you open the back, you will fog the film in the gate as well as the outer layers of the roll of exposed film.

For the winding problem two possibilities. When you opened your camera and saw that the leader of the film was still out of the cassette then either

Why is my film cassette not rewindable?

Now for the film not being rewindable by the camera or by hand would suggest that the tape that holds the film to the cassette spool has failed.
