I know it’s referred to as film grain, but digital cameras also have grain, and the amount of grain will vary from shot to shot depending on lighting, shutter speed etc.
Adding extra fake noise to the movie solves a few problems such as ensuring a consistent look from scene to scene, as well as avoiding video artifacts like banding.
It’s also an artistic choice just like the choice to use telephoto lenses that blur backgrounds into fuzzy balls of light.

- speedgoose 4y agoMany recent shows on Netflix have shots full of digital noise, and I read on HN that’s because of using RED cameras.

- Kye 4y agoThe noise floor seems to get lower and lower with every generation of camera. Eventually, no one will remember a time when using a high gain (ISO) revealed sensor/pipeline noise.
