    How does traditional - as in before AI - photo verification knows the image was not manipulated? In this post the paper is super flat, and I’ve seen many others.

      From reading the verification rules from /r/gonewild they require the same paper card to be photographed from different angles while being bent slightly.

      Photoshopping a card convincingly may be easy. Photoshopping a bent card held at different angles that reads as the same in every image is much more difficult.

        That last thing will still be difficult with AI. You can generate one image that looks convincing, but generating multiple images that are consistent? I doubt it.

            I feel like you could do this right now by hand (if you have experience with 3d modelling) once you’ve generated an image. 3d modelling often includes creating a model from references, be they drawn or photographs.

            Plus, I just remembered that creating 3d models of everyday objects/people via photos from multiple angles has been a thing for a long time. You can make a setup that uses just your phone and some software to make 3d printable models of real objects. No reason preventing someone from using a series of AI generated images instead of photos they took, so long as you can generate a consistent enough series to get a base model you can do some touch-up by hand to fix anything that the software might’ve messed up. I remember a famous lady in the 3d printing space who I think used this sort of process to make a complete 3d model of her (naked) body, and then sold copies of it on her Patreon or something.
