exiftool -S -s -Credit a.jpg | tr '/' ':' | exiftool -d "%Y:%m:%d" -AllDates'<=-' a.jpgIdeally, I'd like to shift the time by +1 hour, too, but I could not figure out how. This does work for a couple of images (say 30% out 10,000) but for the majority I get an error message about minor (?) MakerNotes errors and the image does not change. Sometimes it does not work at the first time, but if I keep trying it is done afterall. I tried to delete the MakerNotes before I apply the above, then it runs through cleanly. But this I really do not want as I'd like to preserve the Makernotes.
Can I jist use the -m option and trust that all will be well (for 10,000) images? Any help appreciated-Thanxx, Mixx
