With iOS 15, Apple is introducing more granular control over the people and places that show up in your Photos Memories, letting you fine tune just who makes random appearances in the Photos app and the Photos widget.
You've already been able to select "Suggest Fewer Memories Like This" when viewing a memory in the "For You" section of Photos or remove a photo from photo suggestions entirely, but now you can choose to feature a specific person less often.
When viewing the For You section of the Photos app, you can long press on an image with a person and select the "Feature This Person Less," option to prevent that person from popping up as often. The Remove From Featured Photos option prevents a specific photo from reappearing.
These new controls for better managing what shows up as a featured image will come in handy when an unpleasant memory pops up, perhaps one featuring an ex-partner or a place that has a negative association.
Over the years, people have complained about the Memories feature in the Photos app and some of the people that it opts to feature.
The prior "Suggest Fewer Memories Like This" option that was available in iOS 14 for memory slideshows has been renamed "Feature Less," and you can select specific people, dates, and places to feature less often in Memories.
It's also worth noting that in a memory slideshow that Apple suggests, you can also now tap on the grid button on toolbar to enter into a view that shows you all of the photos at once. Just long press on it to get a "Hide from Memory" option that makes it disappear.
These new features are available in the Photos app in the current iOS 15 beta. iOS 15 will be in beta testing for several months, with a launch to come in the fall.
