I feel like it’s a pretty good definition to start with but I’d extend it a little further to encompass the techniques you mentioned and also add things like HDR bracketing, and astrophotographer techniques like dark frames and photo stacking. Essentially I think as long as the photo is built up from data captured by the camera sensor(s) and no additional data is “added” to the photo, no upscaling, no substitution, no textural or morphological manipulation of objects in the frame, then it’s still a photo even with sophisticated AI processing. But the moment you upscale, airbrush, or morph anything… not a photograph.
