Aperture-priority ae, F: aperture-priority ae – Canon EOS 60D User Manual
In this mode, you set the desired aperture and the camera sets the
shutter speed automatically to obtain the standard exposure suiting the
subject brightness. This is called aperture-priority AE. A higher
f/number (smaller aperture hole) will make more of the foreground and
background fall within acceptable focus. On the other hand, a lower
f/number (larger aperture hole) will make less of the foreground and
background fall within acceptable focus.
