Title: Removing Face recognition data
Post by: m-photo on November 01, 2019, 11:08:22 AM
Hi there,

Lightroom used to write metadata that I would like to remove.
I found these tags and I wonder:
- are there more tags related to the face recognition ?
- is there a simple command to remove them all or do I have to do it one by one ?

Thank you.

exiftool  -RegionInfoMP= -RegionInfo= <FileOrDir>

This will clear MWG regions and Microsoft regions.  MWG regions are the ones set by Lightroom and the old Picasa program.  Microsoft regions were set by Windows Photo Gallery.

Note that the IPTC is coming out with their own set of tags for defining image regions... Yet another "standard" to add to the mix. :(  To remove these too, you would add -imageregion= to the command.
