If 35mm film can be scanned up to 4K, does that mean I could have old film rolls from my cheap 1990s photo camera scanned to 4K?

I’m pretty sure the camera used 35mm film, and after I got film rolls developed they were returned to me. I’d just have to find them… And then I assume I could pay for them to be scanned?

The camera was really cheap, just one of those all-plastic with a small lens, not protruding from the body of the camera, basically disposable camera-grade except your could reload film. But since it used film, the film was the “sensor” of the camera so to speak, so the quality should still be good, right?

Is this at all possible?

Depends on camera and film.

A cheap lens, small lens or high ISO film (much over ISO 100) will all result in degraded image vs what you’d expect from a modern digital camera, similarly whether the scene is sufficiently in focus may also make scanning to 4K pointless.

When they use film to shoot movies they’re using high quality lenses, a huge lens compared to your point-and-click camera and high quality film because the whole experience is intended to be projected onto a big screen.

The lens quality affects image quality, focus, distortions, etc.

A small lens impacts resolution, but it also affects the speed of film. If you have a huge lens you are gathering a ton of light so can get a better picture from a short exposure of a lower ISO film.

ISO – with film this was a trade off between light sensitivity vs quality. ISO 400 could be more easily used indoors with a regular camera, because it needed shorter exposure, but was grainier than ISO 100 because of how it achieved that sensitivity.
