Description field not exporting from Photos
Photos 5 for Mac is not exporting Description when I choose that option. I'm exporting to JPEG and choose to export Title, Description, etc.
Photos Version 5.0 (141.19.150).
MacBook Pro (Retina, 15-inch, Mid 2015).
Mac OS Catalina 10.15.4 through 10.15.6 have all had the same problem.
I did some exploration:
My husband has the same versions of Photos and MacOS. He tried exporting a random photo from his Photos library after adding a Description and the Description was included in the exported JPEG and recognized in Preview.
BUT -- when I had him import a photo from my camera (Canon PowerShot A1300), add a Description, export 1 photo, and open in Preview, the Description was not exported. We both created a Keyword and a Title -- those and a location were included in the exported JPEG successfully.
Another oddity. My husband learned that one can drag a picture from Photos to the Desktop. I tried that and found something that is odd. IPTC has a substructure for Artwork objects in an image. See https://www.iptc.org/std/photometadata/specification/IPTC-PhotoMetadata#artwork-or-object-in-the-image-structure
The jpeg created by dragging to the Desktop had the description I had created in Photos in an IPTC field for Artwork Content Description. This is of no use to me, because that field is not recognized in the next stage of my usual workflow, which is to use Preview to reduce the image size and then upload a group of photos to a site that needs the IPTC Caption/Description field.
Note: This is the same problem reported in https://discussions.apple.com/thread/251545333
