I'm using On1 Photo raw and when I export it gives me a "caption" field that is causing me no end of problems. How do I remove it?
I can remove Caption-Abstract using
exiftool -iptc:Caption-Abstract= but that's not the right field. I need to keep that one.
See FAQ 3 (https://exiftool.org/faq.html#Q3) to determine the tag name and where it is stored, then consult the Tag Name documentation (https://exiftool.org/TagNames/index.html) to see if this tag is writable.

Thanks Phil.
It says "string/" - does that mean I'm stuck with it?
What is the output of the command from FAQ 3? "string/" shouldn't be the name and group of a tag. You should see something like

Thanks StarGeek. When I do a exiftool -s for the image I find the description "Caption" under XMPToolkit : XMP Core 5.6.0
The "string/" in the Writable column of the tag name documentation means that it is writable as a string but avoided by default so you need to specify the full group name that you see with the -G1 option when extracting. I think this is the XMP-acdsee group because that's the only Caption I can see in XMP. So the command to remove this will be:
exiftool -xmp-acdsee:caption= FILE
- Phil
Thanks Phil
When I run with the -G1 option I see:
[XMP-iptcCore] Caption :
That is unfortunate. Whatever software wrote that tag is in error because this tag is not part of the IPTC-for-XMP specification.
You will need to create a user-defined tag to be able to write this. The attached config file will do it for you, and allow you to delete the Caption tag with this command:
exiftool -config caption.config -caption= FILE

Thank you so much for your help Phil!
I see there are numerous posts on creating automator actions to deal with this so that's what I'll do next.
Alternatively, the XMP can be removed and recopied. The result is that XMP-iptcCore:Caption is removed and the contents copied to XMP-acdsee:Caption, which can be edited normally.

Good point. That is a quick way to remove all non-standard XMP.
