I am a sports photographer, and Getty Images *requires* the use of the IPTC "Personality" field for all athletes shown in the image before submission. I do most of my sorting, culling, IPTC labeling in PhotoMechanic before importing to Lightroom for toning and cropping (No AI anything allowed!). PhotoMechanic supports the Personality field, which I use to insert the subject of the image's name. However, when I search for an athlete in Lightroom's "all searchable fields" , I get a "nothing found" result.
In searching Adobe.com, I don't see "Personality" field supported by Adobe (yet).
It seems that Getty would have enough weight to get Adobe to support the Personality IPTC field.
