Hands appear differently in different positions all over the frame in the photo so I maintain the hand pattern is less consistent and harder than lens blur.

But you’re right as the blur is a fingerprint you can match it to a lens and prove a photo is real that way.

It could be a useful tactic as much of AI detection is a way to find and prove AI fake so far.

Just my guess. I could be wrong:

As the lens blur is mathematically fairly simple and spread across the whole image it’s likely already consistently replicated by AI in a similar way to real photos.

It’s easier for generative AI to spot, “understand”, and replicate a mathematical pattern than the number of fingers on a hand or limbs on a body.

Fuck you

With Dijon mustard!
