The camera may recognize and register faces incorrectly depending 
on lighting conditions, drastic changes in the subject's pose or face, 
and whether or not the subject is wearing glasses. 
The camera can automatically register up to 14 faces. If the camera 
recognizes a new face when 14 faces have already been registered, it 
will replace the lowest priority face with the new one.
The camera can detect up to 5 favorite faces in one scene.
