Aperture Priority; Manual Exposure - Sony DSCHX80/B-AC Manual

[31] How to Use

Aperture Priority

You can shoot by adjusting the aperture and changing the range in focus, or by defocusing
the background. The aperture value can be changed while recording movies.
1. Set the mode dial to A (Aperture Priority).
2. Select the desired value by turning the control wheel.
Smaller F-value: The subject is in focus, but objects in front of and beyond the
subject are blurred.
Larger F-value: The subject and its foreground and background are all in focus.
3. Adjust the focus and shoot the subject.
The shutter speed is automatically adjusted to obtain proper exposure.
Note
If proper exposure cannot be obtained after setup, the shutter speed on the shooting
screen blinks. Although you can shoot as it is, resetting is recommended.
The brightness of the image on the screen may differ from the actual image being shot.
Hint
Smaller F-value (opening the aperture) narrows the range that is in focus. This allows you
to put the subject in sharp focus and blur objects in front of and beyond the subject (depth
of field becomes shallower). Larger F-value (narrowing down the aperture) widens the
range that is in focus. This allows you to shoot the depth of the scenery (depth of field
becomes deeper).
