I've seen quite a few “how to spot ai“ videos that were simply talking about errors in the construction of the image. Too many fingers, weird eyes, weird faces, etc... But AIs are getting better; And I'm not hearing anyone talk about the errors baked into the training data itself. What makes an AI image stand out? -The *Blue* channel on real Digital Photos will *ALWAYS* be more noisy than Red and Green channels. -Consider the hardware used to take the “photo“ or make the “digital painting“ -JPEG compression is image wide, chunks of slightly off tint/hue colors, with purple and green tendencies. -JPEG compression should be more visible around curves in an image, they are formed from 8x8 pixel blocks, but may appear as lattices or grids within individual blocks (DCT Patterns). Sometimes standing out as 2x2 or 4x4 blocks because of the patterning. -If it doesn't have *BOTH* JPEG issues, then its likely AI. -So, non-square JPEG artif
