I'm considering moving 10,000 photos from iPhoto to Lightroom. I spent a lot of time tagging faces in iPhoto. When imported into Lightroom, the face names are stored as keyword tags rather than being incorporated into Lightroom's face recognition system. Is the iPhoto importer unable to interface with Lightroom's face recognition?
Face tags in Iphoto being recognized as keywords in Lightroom after import is the expected behavior (by design) as mentioned in the below article :
I understand that this is the way the importer is implemented and thus the expected behavior. However, it is a bad user experience. Please update your importer to preserve tagged faces from iPhoto when importing into Lightroom. The absence of this feature means I'll either need to spend weeks retagging photos or (more likely) just give up and not use Lightroom. It is quite disappointing that this data is lost when migrating to Lightroom, and this is something that Adobe should address.
