When you turn up saturation then contrast it reveals a lot of little artifacts like this, but the background doesn’t have any. It could be that the subject was AI generated then pasted into a clean background.
Artifacts could exist for other reasons, such as multiple lossy compressions or use of Nightshade, but I doubt either of those would leave the background clean?
I would upload a comparison image of the same process performed on my own artwork which does not create such artifacts, but my instance takes like an hour to upload an image.
Can we please not accuse anyone of using AI without absolutely clear evidence. It can be very demoralizing for the artist to be wrongly accused.
Those are jpeg compression artifacts. Nothing to do with being AI generated or not. It’s normal that a single-color background will stay clean except around contours, as is the case here.
As an old man who used to like porn images (i still do, but i used to too), this is correct.
