In some cases, you might end up deleting a number of photos to the trash in Photos (e.g. when using the Find Duplicates command), but then decide you don’t want to delete the photos after all. Fortunately, deleting photos is not immediately permanent, and there is a way to return recently deleted photos to the main section of the library. To do so:
- Open the library in the Photos app.
- Among the library’s albums in the album list on the left, you should see one named “Recently Deleted”. Select that album to view your recently deleted photos. Note that if you have not deleted any photos in your library, the Recently Deleted album will not appear in the album list.
- Click any photos that you would like to return to the library to select them.
- Click the “Recover” button in the upper right corner of the window. This will “undelete” the photos so they once again appear in the library. The photos will also be returned to any albums they belonged to when they were deleted.
