Unnatural shininess and smoothness

AI generated images frequently have an unnatural smoothness to them. Here's a really obvious example:

These are supposed to be blueberries, but they're way too shiny. They look more like glass than actual fruit!

Here's an example that's a little less obvious:

At first glance, it's easy to miss that this is a procedurally generated image. But if you take a moment and look close, you can see an unnatural smoothness to this image. Compare with this real photograph below:

The real photo has a slight graininess to it, plus the berries themselves display more texture.

Here are more images displaying unnatural smoothness:

Exaggerated facial and body proportions

If a person or animal in an image that appears to be a photograph has cartoonish or caricaturish proportions, that's a sign the image is AI generated.

First, we'll start with a really obvious example. While I don't think the person who had this generated meant for it to be taken as photorealistic, it's still a good example of exaggerated proportions.

Now here's the less obvious example:

If you just glanced at this image, you might think this was a real child. But if you look for a moment longer, you'll notice that her head is slightly too big for her body proportions, and her eyes are slightly too big and round. (And of course, her toes are messed up.)

For comparison, here's a real child:

The real child's head is smaller, and the eyes don't have that cartoony look.

Here's an image of a baby that could pass as real at first glance... until you realize the eyes are too big and round, and it's making Dreamworks face! (Also, the brows and lashes are unnaturally smooth and the skin looks plasticky!)

For comparison, here's a real baby:

Melty-looking detailwork

AI images that are supposed to depict fantasy, divine, and historical figures often feature an extreme level of detailing. But if you look close, you'll see that this detailwork is usually a mess.

Here's a very obvious example:

If you look at her tiara, you can see that the center gem is actually floating above the rest, which is a dead giveaway that this is procedurally generated. Also, her tiara lacks symmetry and evenness where it should have it.

Here's another example:

Again, this is clearly a piece that should have symmetry in the metalwork, but has that uneven melty look so common in AI imagery.

And a less obvious example:

This one isn't as extreme as the others, but if you're familiar with the way AI "melts" details, you can recognize its work. (Also, her right earring is lower than it should be, and where her face is clearly meant to imitate an oil painting, her dress looks like a watercolor painting!)

Meanwhile, here's a real photograph of a tiara:

I'd also like to emphasize here that asymmetry on its own doesn't indicate AI! Many people create asymmetrical designs on purpose. The thing to really watch out for is melty-looking shapes and unevenness in things that shouldn't look melty or uneven.

Unnatural crispness and detail

AI image generators often lean toward high-contrast tones, which frequently makes images look unnaturally crisp. Here's a really obvious example:

Let's compare with a real photo of the Sphinx!

Quite a bit of difference, huh?

This faux Greek statue might be a bit harder:

This appears to depict a Greek-styled statue, but - look at the face! The crispness in the light and shadows gives this away as AI generated. (There's also no staining on the face, even though we see it on the next.)

For comparison, a real statue:
