Virtual copies and Snapshots

1. You can only export one photo at a time with snapshots, because only the most recent snapshot is applied.
2. Since only the latest snapshot is applied, it will be copied with the latest snapshot.
3. If you press CMD and ' at the same time, a virtual copy will be made of the selected photo.
4. With virtual copies, you can export multiple photos at the same time.
5. If you delete the master copy of a photo, then the virtual copy will be deleted as well.
