npub19qm2trjs3p32nwqwry4ufxl4fk9q4utkq53ywueg0yk8cvggra5s79sn8k (npub19qm…sn8k) the real question is "what does this signature aim to protect/validate"?
If it aims to validate that the original image wasn't AI-generated, even if it was edited with Photoshop and friends, or even post-processed by AI, then an EXIF header with the signed metadata should suffice.
If it aims to validate that the image was neither AI-generated nor tampered (including Photoshop), and thus is the genuine raw output of a camera, then it should probably contain a full signed checksum of the image data.
