Intelligent Face Detection allows the camera to automatically detect human faces and set focus and exposure for a face anywhere in the frame for shots that emphasize portrait subjects. Choose for group portraits (in horizontal or vertical orientations) to prevent the camera from focusing on the background.
Faces can be detected with the camera in vertical or horizontal orientation; if a face is detected, it will be indicated by a green border. If there is more than one face in the frame, the camera will select the face closest to the center; other faces are indicated by white borders.
In some modes, the camera may set exposure for the frame as a whole rather than the portrait subject.
If the subject moves as the shutter button is pressed, their face may not be in the area indicated by the green border when the picture is taken.
