The way I see it is that grain makes the film look more detailed than it really is, it can also hide compression artefacts and blurriness.
I don't know the psychovisuals behind that. Maybe it adds some high frequencies that compression often washes out, or maybe acts like some kind of dithering.
As for your eyes, I am pretty sure that they have grain, that's how quantum physics work, you just don't perceive it because your brain filters it out. But again, I don't know how it interacts with film grain.
- plastic3169 1y agoVideo signal without the noise or grain is annoying to watch as it makes everything in the ”out of focus” zone look smooth blurry. Your eyes want to focus yet it is an illusion of depth without an actual depth. Noise texture emphasizes that this is just a 2D plane after all so your eyes can rest and the viewer doesn’t feel like they need glasses. This is just my theory of it based on observation. No research behind it.
