Select direct measurement mode.
Release the WB button briefly and then
press the button until the L icon in
the control panel and viewfinder start
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.

Measure white balance.
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 preset
d-0. No photograph will be recorded; white balance can be
measured accurately even when the camera is not in focus.
5
Check the results.
If the camera was able to measure a
value for white balance, C will flash
in the control panel, while the
viewfinder will show a flashing a. At
default settings, the displays will flash
for about six seconds.
