I have a large library of 71,000 photos and have gone through the dectection phase with many issues.  Is there a way to have Aperture rescan and re-detect faces? I am using version 3.2.1.

    You can select images and use the command "Photos > Detect missing faces" to make Aperture scan again for faces in the selected images.


    What kind of issues are there. Do you want to clear all named faces and start over again?

    Leonie, I did try that but it did not make a difference.  The main issue is that out of the 71,000 photos there are not the appropriate amount of faces being recognized and some that are very present in the photos not showing up at all. I am not the only person who has worked on this library so I am not sure if faces have been dismissed, etc.

    Is it possible at all to add faces, by selecting an image and typing "N", then selecting "Add missing face"?

    Or is the naming of faces completely broken?


    If you suspect, that too many faces have been rejected, there is no easy way to reset that. You can always force a new scan for faces by exporting the version and reimporting it, or exporting the original and than lifting and stamping all adjustments and metadata.


    Have you tried, if repairing your library will activate more faces? Repairing and Rebuilding Your Aperture Library: Aperture 3 User Manual
