I converted a raw Sony file (.ARW) to a .DNG format with Lightroom.
Now I would like to write new keywords to the IPTC of this .dng file with exiv2.
The command exiv2 -P I test5.dng gives me the error message:
"Error: Directory Sony2 with 25665 entries considered invalid; not read."
What can I do? If exiv2 won't be able to do the job, any other software that might work?
