As you name the people that appear in the photos in the library, the number of named faces quickly grows. Locating photos of a particular person is a simple process.
In the Library inspector, select Faces.
In Faces view, enter the name of the person you are looking for in the search field.
Aperture displays the snapshot of the person whose name you entered in the search field, removing all others from view.
In Faces view, click the Reset button (with an X) on the right side of the search field.
Snapshots for all the people identified in the library reappear in Faces view.
You can use the Filter HUD in the Browser to perform more complex searches for people in your photos. For more information, see Search using a combination of criteria.
