Certain masters missing - unable to export photos
Hi Guys,
I have been exporting the edited versions of my pictures from Photos to an external hard drive by highlighting the photos I want to export, then selecting File -> Export. This worked perfectly for 1,183/1,203 of my photos, but for the other 20 I got an error message reading "The export operation failed to create files for the photos listed below". Next to each file listed, the error reads: "Could not load image (1,019)".
I have searched for the filenames of the photos causing the problems in Spotlight and Finder, and I have gone into the 'Masters' folder in iPhoto Library to search manually, and the masters for those photos appear to be missing. Basically my question is: What do I do from here? Am I going to have to simply delete these pictures from Photos, find an old backup (which will be a nuisance) and reimport them?
Thanks for any input!
Note: I checked my Photos Preferences and 'Copy Items to the Photos Library' IS checked under 'Importing'
