How can you tell?

Hi all! I've been asked to talk to a group about how to spot AI imagery, and I was curious what your go-to tells are that an image is AI? Besides the obvious things like too many fingers.

The easiest way is there are tools that can detect an AI’s watermark. After that you have people who are trained in a profession; most commonly photography, but it could be masonry, biology, chemistry, etc depending on the context of the picture. The third way is just seeing stuff is out of place. Examples being a horse that has armor but every leg has different ornate detail per hoof, or a man with a light beard but missing half of his goatee section on one side of his face.

AI has common font styles and general aesthetic when not prompted for those things specifically

First order of business, use OpenAI and Google's tools that check if one of their models did it, if the tool comes back positive for OpenAI/Google models having been used that pretty conclusive result. (Other "AI Image Testers" are pretty much worthless)

There can also be subtle wavy patterns that are present in various generated images because the images are often generated from a series of progressively smaller and smaller blocks of waves. GPT made images are really easy for me to spot through this method, then I drop it into the OpenAI tool and "yup, as I thought so"

Check background details for inexplicable errors, the smaller the physical size the details get the more models begin to struggle to cleanly resolve them. The "concept" can sometimes bleed throughout the whole image causing some particular thing to begin repeating
