> This grain, formed from tiny particles during the film’s development, is more than just a visual effect. It plays a key role in storytelling by enhancing the film’s depth and contributing to its realism.

I never understood the “grain = realism” thing. my real eyes don’t have grain. I do appreciate the role of grain as an artistic tool though, so this is still cool tech

Film grain and 24fps are both examples of people being far too attached to the technical limitations of film.

23.976 fps has been put on a pedestal as the "correct" look. Just look at the reaction to The Hobbit. However it does provide some objective advantages. 60 fps requires more lighting. Adding more lights means more electric setup and heat for actors in heavy makeup and costume. In post production that's more frames to edit.

Isn't it strange how people accepted much bigger changes like sound and color but are now balking at higher frame rates?

23.976fps is only "correct" when telecining to a 59.94Hz format. 24fps round is the "correct" format in terms of actual filmmaking. I don't know of many films specifically shot at 23.976fps.

> 60 fps requires more lighting.

Assuming the comparison uses the same image sensor for each.

If that were an argument then frame rates would have increased with more efficient lighting.

Those came much earlier in the history of film and have a much more significant qualitative impact.

Higher frame rate has a huge impact on the smoothness of motion and really benefits actions movies.
