We add IPTC data to images we collect with GigEVision cameras. The libiptc library (available in OBS) works great. There are not so many client programs. The Linux package comes with a program called iptc that allows access to this information: Utility for viewing and modifying the contents of IPTC metadata in images Usage: iptc [OPTIONS] [FILE]... Examples: iptc image.jpg # display the IPTC metadata contained in image.jpg iptc -m Caption -v "Foo" *.jpg # set caption "Foo" in all jpegs of the curr. dir. iptc -a Keywords -v "vacation" *.jpg iptc -a 2:25 -v "vacation" *.jpg # either command adds keyword "vacation" to all jpegs iptc -d Keywords:1 image.jpg # removes keyword number 1 (the 2nd) from image.jpg iptc -d Keywords:all image.jpg # removes all keywords from image.jpg Operations: -a, --add=TAG add new tag with identifier TAG -m, --modify=TAG modify tag with identifier TAG (add if not present) -v, --value=VALUE value for added/modified tag -d, --delete=TAG delete tag with identifier TAG -p, --print=TAG print value of tag with identifier TAG --add-version add IPTC version number into the headers --add-encoding add text encoding specification (UTF-8) into headers Options: -q, --quiet produce less verbose output -b, --backup backup any modified files --no-sort do not sort tags before saving Informative output: -l, --list list the names of all known tags (i.e. Caption, etc.) -L, --list-desc=TAG print the name and description of TAG --help print this help, then exit --version print iptc program version number, then exit On Fri, Aug 30, 2019 at 8:20 AM Carlos E.

Hi,

I did a little test in Windows with some photos. Using the Nikon supplied tools (ViewNX-i/Capture NX) I wrote the "XMP/IPTC" copyright profile on a few photos. But on Linux there was no trace at all of this.

Forget it. Before posting this I took a second look on the photos on Windows, and whatever that is was not actually written: loading the photos again the info is not there, even though it asked me to "save" :-(
