Shutter-Priority AE
In this mode, you set the shutter speed and the camera automatically
sets the aperture to suit the brightness of the subject. This is called
shutter-priority AE. A fast shutter speed can freeze the motion of a fast-
moving subject and a slow shutter speed can blur the subject to give the
impression of motion.
