Taking Photographs—White Balance
Keeping Colors True
57
5 Frame the reference object so that it fills the
viewfinder and press the shutter-release but-
ton all the way down to measure a value for
white balance (the shutter will be released, but
no photograph will be taken). If the camera is
able to measure a value for white balance, the
letters
will flash for two seconds in the
control panel shutter-speed display, and the
viewfinder shutter-speed display will show a
flashing
. The new value will be recorded
when the shutter-release button is pressed half-
way or when the exposure meter turns off (auto
meter off;
151). Until white balance is mea-
sured again, this value will be used in all subsequent photographs taken at
a setting of Preset (PRE).
If the camera is unable to measure a value for
white balance, the shutter-speed/aperture dis-
plays in the control panel and viewfinder will
show a flashing
. Press the shutter-re-
lease button halfway while this indicator is
flashing to return to Step 4. Repeat Steps 4
and 5, taking care to adjust settings to avoid
extreme under- or over-exposure.
If white balance is not measured before the exposure meters turn off auto-
matically, the camera will revert to the last measured preset white balance
setting. To set a new value for white balance, repeat Steps 3–5.
Note that the camera can store only one value for preset white balance at
a time. Measuring a new value will delete the previous value from memory.
During Recording
If preset white balance is measured while images are being recorded to the memory
card (
34), the result ( / or ) will not appear in the viewfinder and
control panel until recording is complete. We recommend that you wait until recording
is complete before measuring preset white balance.
