   Apple doesn't address the modified photo replay situation, where you take a picture of an already edited image.

   Photoshop / AI-gen an image -> display on a high-resolution monitor -> photograph the monitor with iPhone 18 Pro -> valid Apple Reference image.

   To get valid reference photos, you can go to the actual physical location, put the iPhone/monitor in a cardboard box to block external light, then photograph the monitor. Paint the inside of the box using Vantablack (stopping reflections) and cover the LiDAR projector with tape.

   I can't wait to see Apple Verified™ photos of UFOs flying over the Golden Gate Bridge.

      It also doesn't prevent you from staging an image or anything that's existed since photography was invented. But that's not the problem they're trying to solve.

      Photoshop has existed for decades and so has fake images. This is a low friction way to attest "this image came from an iPhone sensor and Apple approved it". It will still take the usual image forensics to determine if the scene it depicts is legitimate.

         It is the problem that they say they're trying to solve, though. They specifically say "where the essential role of a photograph is to prove that something actually happened".

         It fails the reasonable person test to say that the "something" in that phrase refers to the act of taking the photo itself.

         Likewise in "distinguish between photographs that depict real events and...".

            This is so stupid. This makes it like, a thousand times harder to fake a photo than it would otherwise be. You pedants imagining a way to fake it doesn't change that.

               The problem with this thinking is twofold:

               1) Whether it actually meaningfully increases the difficulty of a forgery remains to be seen. Despite their initial language about discerning real events, we see no details here about what scene information is used.

               2) It increases the potential value of a forgery because now your forgery is attested by Apple.

               So it either makes it easier to defraud people or more worthwhile to put in the effort to defraud people or both. None of those outcomes are great.

                  You worry that a technology that you have never used nor evaluated might not work in practice...

                  Therefore because of your worry (which is based on remarkably little information), it's a bad technology?

                  Come the fuck on. That's beyond luddite bullshit.
