Captions not copied when importing images into Photos
When viewed on Preview my tiff photos shows a description/caption both in IPTC:Caption/Description and in TIFF:Image Description.
But when imported to Photos, the description is not shown in the Info Box (it says "Add a description")
OTOH, when adding a description in Photos and exporting -- Preview does show the caption in the above two fields.
I have tons of photos with such descriptions/captions (exported from Lightroom Classic). How do I get these descriptions into Photos?
TIA
