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. The smaller the aperture (larger f/number), the
wider the depth of field (range of acceptable focus). The larger the
aperture (smaller f/number), the narrower the depth of field.
