> Officially supports Exif data

Probably the best news here. While you already can write custom data into a header, having Exif is good.

BTW: Does Exif have a magnetometer (rotation) and acceleration (gravity) field? I often wonder about why Google isn't saving this information in the images which the camera app saves. It could help so much with post-processing, like with leveling the horizon or creating panoramas.

Does the meta-data have support for opting in/out of "AI training"?

And is being able to read an image without an opt-in tag something that has to be explicitly enabled in the reference implementation's API?
