57 Taking Pictures and Recording Video Clips
If the setting is anything other than the default Auto setting,
the icon for the setting (in the previous table) 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 White
Balance setting resets to the default Auto setting when you
turn the camera off.
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 the best quality 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).
Tungsten The camera balances color based on
incandescent or halogen lighting (typically
found in homes).
Fluorescent The camera balances color based on
fluorescent lighting.
