The self-timer lamp on the front of the camera will blink
immediately before the picture is taken. If the two-second timer is
selected, the self-timer lamp will blink as the timer counts down.
Intelligent Face Detection
Because it ensures that the faces of portrait subjects will be in focus, Intelligent Face Detection (pg. 23) is
recommended when using the self-timer for group portraits or self-portraits. To use the self-timer with
Intelligent Face Detection, set the timer as described in Step 1 and then press the shutter button all the way
down to start the timer. The camera will detect faces while the timer is counting down and adjust focus
and exposure immediately before the shutter is released. Be careful not to move until the picture has been
recorded.
