Chapter 2: Taking Pictures and Recording Video Clips 47
ISO Speed
This setting adjusts the sensitivity of the camera to light. When
ISO Speed is set to Auto , the camera selects the best ISO speed
for the scene.
NOTE If the camera is in ACTION , LANDSCAPE , or VIDEO
mode, the ISO Speed will always be set to Auto and the
ISO option in the Capture menu will be grayed out.
Lower ISO speeds allow slower shutter speeds, and will capture
the best quality pictures with the least amount of grain (or
noise). 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 higher shutter speeds, and can be used
when taking pictures in dark areas without a flash, or pictures
of fast moving objects. Higher ISO speeds produce pictures
with more grain or noise and, thus, can be of lower quality.
1 In the Capture menu (page 40),
select ISO Speed .
2 In the ISO Speed menu, use the
buttons to highlight a
setting.
3 Press OK to save the setting and
return to the Capture menu.
If the setting is anything other than the default setting of Auto ,
the number value for the setting 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 (unless ISO Speed is checked in
the Remembered Settings menu - see page 90).
