Aperture-Priority AE
If you select the aperture, the camera will automatically
set a suitable shutter speed for appropriate exposure.
Which aperture you select will have the following effect
on your pictures:
APERTURE-PRIORITY AE
Choosing a larger aperture (smaller f-number)
Depth of field will be shallow. In other words, details in
front of and behind the plane of best focus will be
increasingly blurred – an effect that is very desirable,
for example, in portraiture.
Choosing a smaller aperture (higher f-number)
Depth of field will be deep. In other words, you will
capture great depth in sharp focus. This is very
desirable, for example, when shooting scenery.
