Measure white balance.
In the few seconds before the
indicators stop flashing, frame the
reference object so that it fills the
viewfinder and press the shutter-release button all the way
down. The camera will measure a value for white balance and
store it in the preset selected in Step 3. No photograph will
be recorded; white balance can be measured accurately even
when the camera is not in focus.
