People identification features improved recognition for individuals, and it is easier to correct naming mistakes in the People album. There is an option to Feature Less to let Photos know that you would prefer to see less of a specific date, place, holiday, or person across Featured Photos, the Photos widget, Memories, and highlighted in the Library tab.

In iOS 15, Photos features a richer Info pane to view information about the photo, such as the camera, lens, and shutter speed, the file size, or who sent a Shared with You photo in Messages. You can also edit the date taken or location, add a caption, and learn about items detected by Visual Look Up.

The Photos image picker, including in the Messages app, now allows you to select photos in a specific order for sharing. Third-party apps can also offer simpler selection workflows when you grant access to specific content in the Photos library.
