Hello Victor, thank you very much for your hint. After some reading I found http://www.sno.phy.queensu.ca/~phil/exiftool/exiftool_pod.html#copying_examples
Simply copying did not work; what worked partially was*: 1. **exiftool -exif:all= -tagsfromfile @ -all:all -unsafe bad.jpg** 2. ****exiftool -tagsFromFile src.cr2 dst.jpg* ** After that I could read all the EXIF information from the RAW (RW2) in the .jp2 with exiftool image.jp2 Unfortunately I could not find any viewer (for Mac) which could actually read the newly created EXIF: - Preview.app displays the same (non-)information as before - GIMP does not show the information - ToyViewer does not display any EXIF information Briefly: I am not sure if the data is written correctly by exiftool as only exiftool itself can read the information it wrote.
