Canon 0296B002 Digital Camera User Manual

In this mode, you set the desired aperture and the camera sets the shutter speed
automatically to suit the subject brightness. This is called aperture-priority AE.
A larger aperture opening (smaller f/number) will result in a blurred background
ideal for portraits. This occurs because a lower f/number decreases the depth of
field (range of acceptable focus). On the other hand, a smaller aperture opening
(larger f/number) will make more of the foreground and background fall within
acceptable focus. A smaller aperture opening increases the depth of field.
