Deleting Duplicate Photos

It is a bit weird - Photos 8 on Ventura is spending a lot of time to search for duplicates, but using it only to remove the duplicates and clutter from the Days and Memories, to hide them from us.

As a work-around on Ventura or earlier: To find candidates for duplicates look at the photos that have been removed from the Days - these are either screenshots exact duplicates or similar photos. You need tow helpers:

• Select all photos in the Days view and add them to a new album, call it "Curated".
• Then create a new smart album with the two rules
  • Album > is not > Curated
  • Photo > is > screenshot
• Combine the two rules with "Match Any"

Now you can step through this smart album and check the remaining photos for duplicates. Select a photo, ctrl-click it and use "Show in All Photos" to see, if there is a duplicate, then delete the one you do not want.

That utility was added in a later version of the system (Ventura, as I recall).
