    Hasn't this crossed over into being a philosophical question? You want to attest to reality or provenance. But then you start making lists of "acceptable" changes: file format; compression; color-correction; size; taking "medium" into account... It then slowly slides into "average human perceptibility"; "irrelevant details"; keeping the "spirit" of the image intact; judging the intention or motive of the user or of the viewer; aligning the image with "values"; appropriate/legal use... etc. Not sure what the end-game is?

    We are trying to make images in the AI era be as reliable as they were pre-AI? But they were not reliable pre-AI, it was just more difficult to intentionally doctor them.

      I think for photojournalism it should be original raw image, as captured in camera — zero edits for colour correction/cropping/filesize etc — platforms can link a digital sig from a postprocessed version but you keep the provenance proof tied to a published original.

        ok, point camera at a screen. let's counter that by also taking 360° image with secondary camera. Ok build some props, let's add gps into it. fake gps. let's add inertial tracking and self-destruct on tamper. Ok, but we really need a fake image, here is our badge, give us signing keys for special use case...

        You cannot replace honesty with tech.
