I have keyworded a bunch of files in Adobe Bridge, but forgot to put a few (identical) words at the start of each file in the IPTC Core fields "Description" and "Title. I believe those are the same as ObjectName and Caption-Abstract and XMP "Description" and "Title".
So if the files have the fields "blue banana on pink background", I want to change the fields to "yummy delicious blue banana on pink background". Essentially, just add "yummy delicious" at the start.
How would I go about doing this?
If the words might be different, you could do this
exiftool "-Description<yummy delicious $Description" "-Title<Tasty $Title" /path/to/files
If you are adding the same words to both, then you could use
exiftool -api "Filter=s/^/yummy delicious/" -TagsFromFile @ -Description -Title /path/to/files
If you want to add in the IPTC IIM tags, just add in Caption-Abstract and ObjectName the same way.
Thank you, that worked perfectly!
