Based on the available answers, photographic film is generally made with gelatin, and there do not appear to be any widely available vegan film options.

Community responses indicate that Kodak and Fuji have researched alternatives, but still state that they cannot replace animal-derived gelatin in film. A PETA FAQ cited in the discussion also says they are not aware of any film made without gelatin. That strongly suggests that conventional still film uses gelatin as part of the emulsion layer.

For Polaroid-branded instant film, the situation is less clear from the answers. The original Polaroid company no longer manufactured the film, and the later producers had to recreate the process from scratch. The discussion suggests contacting the manufacturer directly if you need confirmation on current materials.

So, the practical answer is: assume essentially all mainstream photographic film, including instant film, uses gelatin unless a manufacturer explicitly says otherwise. If avoiding animal products is important, digital photography is the most reliable alternative mentioned in the discussion.
