P, A, S, M, and C mode
Aperture—also known as f-stop, controls
the size of the lens opening, which determines
the depth of field.
Larger aperture settings (larger f-number)
keep both foreground and background sharp;
good for landscapes and well-lit conditions.
Smaller aperture settings make the
foreground sharp and background blurry;
good for portraits and low-light conditions.
The highest and lowest aperture settings may
be affected by optical zoom.
Shutter speed—controls how long the shutter stays open. A shaking
hand icon
warns of slow shutter speeds. (To prevent camera shake,
use a tripod for slow shutter speeds.)
Exposure Compensation—controls how much light enters the camera.
Add or subtract up to 2 EV in 0.3 EV steps. If the picture is too light,
decrease the setting; if it’s too dark, increase the setting.
Flash Compensation—controls the flash brightness (brighter: +0.5,
+1.0; less bright: -0.5, -1.0). You must be within flash range. Unavailable
if flash setting is Off.
ISO—controls sensitivity of the camera sensor (80, 100, 200, 400, 800).
Higher settings are more sensitive to light, but may produce unwanted
“noise” in a picture. You can only use ISO 800 if you are in the 1.1 MP
Picture Size setting. (See
Picture Size, page 20 .)
Children Action pictures of children in bright light.
Backlight Subjects that are in shadow or “backlit” (when light is behind
the subject).
