This is the most famous tell-tale sign of AI-generated people. Artificial intelligence is incredibly good at faces, hair, and clothes now. It is still, even in 2026, surprisingly bad at hands. Hands have complex joints, overlapping fingers, shadows, and nails. AI often creates an extra finger, or a missing finger, or fingers that are the wrong length.
In this image, her left hand is the uncanny valley. It is close to human, but not quite human. Once you see it, her smile also changes. Her smile is a little too symmetrical. Her eyes are a little too perfect. Her skin is a little too smooth, with no pores, no blemishes, no real texture, even though the photo is supposed to be old and grainy. She does not cast a completely natural shadow on the floor either. Her feet disappear into the bottom of the image, cut off, with no shoes clearly visible.
