sound.

Take the picture.
Check the focus and exposure, then
press the shutter button completely to
take the picture (p.127).
If the focus is way off, face detection will not be possible. If the lens
enables manual focusing even while the lens focus mode switch is set to
, turn the focusing ring to attain rough focus. The face will then be
detected and
will be displayed.
An object other than a human face might be detected as a face.
Face detection will not work if the face is very small or large in the
picture, too bright or too dark, titled horizontally or diagonally, or partially
hidden.
The
focusing frame might cover only part of the face.
