Controlling  Exposure
In 
 (auto) and 
 (scene) modes, the camera automatically adjusts shutter 
speed and aperture to produce optimal exposure.  In PSA, and modes, 
shutter speed and aperture can be adjusted to suit the user’s creative intent.

How it works
When to use it
Best choice in most situations.
High shutter speeds freeze ac-
tion.  Low shutter speeds sug-
gest movement by blurring mov-
ing objects.
Large apertures (small f/-num-
bers) soften background details 
and let more light into camera, 
increasing range of fl ash.  Small 
apertures (large f/-numbers) in-
crease depth of fi eld,  bringing 
main subject and background 
into focus.
Use when you want complete 
control over exposure.
User controls both shutter speed 
and aperture.
