Before Measuring White Balance:
•
Place a neutral gray or white object under the lighting that will
be used in the final photograph. In studio settings, a standard
18% gray panel can be used as a reference object.
•
Note that exposure is automatically increased by 1 EV when
white balance is measured using a neutral gray or white
reference object. In mode M, adjust exposure so that the
exposure indicator shows ±0 ( 0 190).
