59 Taking Pictures and Recording Video Clips
ISO Speed
This setting adjusts the sensitivity of the camera to light.
When ISO Speed is set to the default Auto setting, the
camera selects the best ISO speed for the scene.
Lower ISO speeds will capture images with the least amount
of grain (or noise), but result in slower shutter speeds. If
taking a picture in low light conditions without a flash at ISO
100, you may want to use a tripod. In contrast, higher ISO
numbers allow faster shutter speeds, and can be used when
taking pictures in dark areas without a flash, or when taking
pictures of fast moving objects. Higher ISO speeds produce
pictures with more grain (or noise).
1. In the Capture Menu (page 48),
select ISO Speed.
2. In the ISO Speed sub-menu, use
the buttons to highlight a
setting.
3. Press the button to save the
setting and return to the Capture
Menu.
If the setting is anything other than the default Auto setting,
the icon for the setting (as shown in the ISO Speed sub-menu)
will appear in the Live View screen. The new setting remains
in effect until it is changed again or until the camera is
turned off. The ISO Speed setting resets to the default Auto
setting when you turn the camera off.
NOTE: The ISO Speed setting does not apply when
recording video clips.
