Aperture-priority AE Settings (Av)
Larger aperture value
When you set the aperture, the cam
era automatically selects the correct
shutter speed to suit the lighting condi
tions around the subject. This is called
Aperture-priority AE.
A smaller aperture value (i.e. larger
aperture) is suitable for taking beautiful
portrait photographs, with effectively
graduated of blurred backgrounds.
However, with a small aperture value,
landscapes will blur.
A larger aperture value (i.e. smaller
aperture) gives a greater depth-of-field
suitable for clear photographs of
expansive landscapes, where every
thing from nearby objects to back
ground details are sharply in focus.
1. Set the command dial to Av .
2. Turn the electronic input dial to the
desired aperture value.
