Aperture-Priority AE
In this mode, you set the aperture value, and the camera automatically sets the shutter speed
to suit the brightness of the scene. This is called Aperture-Priority AE.
By setting a smaller aperture value (larger aperture), you can blur the background to make the
subject stand out as in a portrait. Or, by setting a larger aperture value (smaller aperture), you
can increase the depth of field to make both the foreground and background look sharp.
