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.
That's pretty much how the Apple one works. The raw sensor data is signed. But you have to process it because raw sensor data is unviewable.
Provide the raw original, and the exact processing steps used to get the presentable one.
