People love the fact that Google Photos groups photos together by faces in the People section. And, they hate it when it doesn’t get the people right. Now you can fix this with the Edit People option.
This new feature is available on all 3 platforms: computer/web, Android, and iOS.
Every picture has an info panel. On the computer/web version you click the i for info and it opens up the panel to the right. On mobile, you just swipe up on the picture to reveal the info panel.
One section of the info panel is the People or Pets that are found in the photo. In this photo it notice 2 people but not the third.
