bipface said in forum #415127:
just want to point out these flagged reiwa_no_sherlock posts, despite being PNG files, have a strange type of noise throughout which almost looks like jpeg_artifacts but not quite; also the background is full of noise, not solid white.
it's possible this was caused by bad post-processing/scaling,
but i think it's more likely to be caused by a badly-trained AI model.
i've spent a lot of time staring at compression artefacts over the years and i don't think i've ever seen anything quite like this in legitimate artwork.
I also looked at the noise and it looks weird. The pattern at the edges of the image is different. Overall it is a wavy, repeating pattern. Not typical for filters or compression. It is also affected by how close the characters (hair, feet, hands) are from it. post #10604257 even shows a diamond like shape (watermark) at bottom right hidden in the noise. The noise also increases close to intersections (like splitting hair strands). This would be typical for a glow effect, but a glow effect would not create the repeating noise pattern. A repeating, wavy noise pattern is typical for diffusion models, which start with random noise, which is shaped until an image emerges.
