Aperture 3 expands on the power of Faces in iPhoto ’09. Not only can you view the people you name across the entire library, you can now see them in individual projects. And the new Show Unnamed Faces pane displays all the detected-but-not-yet-named faces in a project to help you easily add names.

Now you can use GPS location data to explore your photos by the places they were taken. Better still, find them on an interactive map.

Faces automatically detects faces in your photos. Once a face is detected and identified, Faces can recognize that face and then scan your entire library — or individual projects — to find others just like it. It can even find a specific face in group shots. The more you use Faces, the smarter and more accurate it gets, making it easier to find shots of a particular person.

Put a name to the face.
When Faces shows you an unidentified face, simply type in the person’s name. When you export your final images, the name is embedded as a keyword.
