Canon EOS 10D - Manual (Page 84)

Aperture-Priority AE
In this mode, you set the desired aperture and the camera sets the shutter speed automati-
cally to suit the subject brightness.
The larger or brighter the aperture (lower f/number) the more blurred the background will
become. This effect is ideal for portraits. The smaller or darker the aperture (higher f/number),
the clearer the focus will be for both near and far objects (wider depth of field).
