    I'm trying to think of recent real-world examples where the reality of the photo was of major importance. Photographs just don't seem to have the same significance, even as potential verification of their realness becomes more achievable.

      An everyday scenario is Real estate photography and Facebook marketplace where people are having a field day AI faking photos.

      Having a tick showing the photo is verified real would add a lot of trust to online platforms.

      There’s been a few, but it’s becoming so common people have stopped noticing, but here’s a few recent ones:

      There’s now even a wiki article on the usage of AI generated images in American politics, mostly dealing with the obvious slop that Trump has produced, rather than insidious edits of real images

      Entering photos as evidence in a legal proceeding is currently bizarrely complex. You actually have to admit an expert witness to testify that the software used to process a photograph will not introduce artifacts. Even if you are simply zooming in or cropping an image.

        Makes sense - there&#x27;s lots of ways to do it wrong. If you crop a jpeg and re-save it as a jpeg, you&#x27;ll introduce artifacts.

        True I can see there being issues in legal system yes. The Kyle Rittenhouse trial was a good covid-time diversion and I remember much consternation and fuss about the zooming&#x2F;enhancement of some of the video evidence.
