❚❚Measuring a Value for Preset White Balance
1
Light a reference object.
Place a neutral gray or white object under the lighting that will be used in the
final photograph. In studio settings, a standard gray panel can be used as a
reference object. Note that exposure is automatically increased by 1 EV when
measuring white balance; in exposure mode M, adjust exposure so that the
electronic analog exposure displays shows ±0 (pg. 84).
2
Set white balance to L (Preset manual).
Press the WB button and rotate the main command dial until L is displayed in
the control panel.
3
Select direct measurement mode.
Release the WB button briefly and then press the button
until the
L icon in the control panel starts to flash. A
flashing D will also appear in the control panel and
viewfinder. At default settings, the displays will flash for
about six seconds. To exit without measuring a value for
preset white balance, press the WB button again.
