I’ve noticed a lot of the time you can tell an image is AI generated because it has a shiny/glossy lighting look to it.

Has anyone figured out why this is the case?

Maybe because the image is generated from Gaussian noise in diffusion models, while the real photo pixel entropy doesn't distribute like this.

What happens if you feed non-Gaussian (e.g. pink or brown, or sufficiently correlated) noise into the model instead?

Ask HN: Why are AI generated images so shiny/glossy?
