Shooting - Selecting Particular Effects
Setting the Aperture
When you set the aperture in the aperture-priority AE mode, the camera
automatically selects a shutter speed to match the brightness. Selecting a lower
aperture value (opening the aperture) allows you to blur the background and
create a beautiful portrait. A higher aperture value (closing it) brings the entire
range from foreground to background into focus. The larger the aperture value,
the greater the range of the image brought into clear focus.
