Nikon N4004s - Aperture-Priority Exposure Mode

APER T URE-PRIORITY EXPOSURE MODE
The microcomputer in the N4004s automatically selects the correct shutter speed to
match the aperture you set. This
is the recommended mode when depth of field is
your prime consideration. To create softer, less distinct backgrounds, as in portraitures,
use wider apertures. For overall sharp, clear pictures, such as scenic photography,
use smaller apertures.
