[QUOTE="WayneF, post: 480244, member: 12496"] There can be ifs and buts, but certainly more true than not. :) The concept is certainly true. The edited raw change LISTS (the xmp data) might be saved in the original NEF file, Adobe has that option too. The raw data is not changed, it is an entirely different format, and the Bayer process is sort of a resampling anyway, it cannot be undone. And there would be no point of it, we have the LIST. It would NOT be a lossless edit if the raw data could be changed. Lossless is a great advantage, but it's more nearly a requirement instead of a planned feature. :) This sidecar file manipulation might make the file format incompatible with the camera, not expecting that. We cannot put edited JPG back in the camera either, it won't be accepted. There would really be no point of it, but even if we could, and even if we did put revised raw back in it, the camera shows the embedded JPG, it does NOT show the raw data. The actual question is probably if the raw editor also bothers to change, or even keep, the embedded JPG? How could it change it? Is its Exif data updated to reflect it? :) The embedded JPG is full size (for the LCD zoom feature), and Adobe saves its own thumbnails. And the embedded JPG and the raw data share the same one set of Exif, but only the JPG data is affected by it. [/QUOTE]
