In this mode, you choose the aperture (f/-number) and the camera automatically sets
the shutter speed for optimal exposure according to subject brightness. Lower aperture
values (larger apertures) reduce the depth of the area that appears to be in focus
(depth of field), blurring the background. Higher aperture values (smaller apertures)
increase the depth of the area that appears to be in focus in front of and behind the
subject.
