Ten Ways to Search in Photoshop Elements 11
Search for people.
Elements provides a great, although not perfect, solution for identifying and labeling people. As people are identified, keyword tags are automatically added to the Keyword Tags panel.
The Organizer has two buttons for tagging people. By default, you see only one button. However, if you double-click a photo and zoom it in in the Media Browser, a second button appears.
The Add People button is always present in the Media Browser. The second button — Missing People — appears only when you double-click a photo in the Media Browser to open it.
