Sony's analogous solution (https://authenticity.sony.net/camera/en-us/ https://authenticity.sony.net/camera/en-us/) claims 3d depth information is built in, I'm sure Apple could do the same given at least some iPhone models have LiDAR on the back
- tristanj 16d agoThis would work for close up shots taken on iPhone, but not landscape shots. The infrared dots the iPhone LiDAR projects are too weak to appear over long distances. Also the dots can be trivially blocked by putting your finger over the sensor, sometimes improving photo quality. I do this frequently when I want to take a photo through a window. The absence of the dot matrix tells the iPhone to focus on the background far away instead of the windowpane.

- amanj41 15d agoI see, yeah good point. Perhaps the lack of reliable depth data also be baked into some signed metadata property. Wouldn't tell you definitively if something were fake, but could be a context clue if a particular photo were dubious I suppose.
- Cthulhu_ 15d agoWhat they could do instead is record a video while taking a photo, the subtle movements (at least if handheld) might have enough information to get an approximation of depth (parallax).
