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?

Short answer is Yes but I wouldn’t look at “quality” in the context of a movie’s resolution: 720p, 1080p, 4k…

That’s not really how film works. The ISO rating on film is all about the sensitivity of the light-absorbing crystals on the film, also called film grain. The higher the film’s ISO, the larger the crystal grains will be and the more light they can absorb. That said, the larger the grain, the less fine detail you can capture. This can be interpreted as “noise” (but it really isn’t).

So, when it comes to scanning film, you are scanning those grains. The higher resolution of the scan, the more defined those grains will be (which is good). A 4k scan of a high ISO film wont look like it’s 720p. It will look like it’s 4k but “noisy”.
