Faces are very well done these days, you can go to https://thispersondoesnotexist.com/ and keep refreshing images. Eventuall you’ll notice little things, like earrings not matching or sunglasses being 2 different halves melded together, hats and hair can look weird, etc
But most of them appear very human
That’s wild. Some of them are really good, but I see what you mean once you keep refreshing the page. Glasses are a good tell once you look closely. Earlobes also appear to be difficult to perfect as well.
I went back to the NYT article and tried again with my goldfish memory using that deduction and got 6/10.
Also, these are all emulating professional camera conditions. In a more standard phone photo scenario, the lower quality can lead to all sorts of weird looking illusions in real photos that can make them look ai generated. I was playing with some AI photo editing and saw some things that looked off which I thought was the generation messing up, but after checking the original photo again I saw that the weird stuff was actually in the original photo due to weird shadows or motion blur.
