Live View gives you an intuitive, familiar way to photograph playful pets or children on the move. Just flip a switch and you're ready to go. When Live View is activated and new full-time-servo AF (AF-F) is selected, the camera keeps subjects in focus without having to press the shutter-release button - convenient for photos and movies. There is also new face-priority AF that locks focus on faces, even on people not directly facing the camera. Live View makes D3100 as easy to use as a compact camera.
Three AF modes - single-servo AF (AF-S), full-time-servo AF (AF-F) and manual focus (MF) - are available when using Live View or shooting movies.
For movies, use AF-F with subject-tracking AF. These help maintain focus on a selected subject and work together to continuously track a subject as it moves through the frame, realizing camcorder-like focusing.

When using Live View or shooting movies, choose from four AF-area modes depending on the subject: normal-area AF, wide-area AF, face-priority AF, and subject-tracking AF.
