In this mode, you set the desired aperture and the camera sets the
shutter speed automatically to obtain the correct 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.
