Taking Photographs—White Balance
Preset White Balance
Preset white balance is used to record and recall
custom white balance settings for shooting under
mixed lighting, to compensate for light sources
with a strong color cast, or to replicate the white
balance used in an existing photo. Two methods
are available for setting preset white balance:
Description
Neutral gray or white object is placed under lighting that will be used
in fi nal photograph and white balance is measured by camera.
Method
Measure
white balance
White balance value is copied from photo taken with D70S (if de-
sired, source picture can be RAW image modifi ed using white bal-
ance adjustment option in Nikon Capture 4 version 4.2 or later). Copy from
existing
photograph
The camera can store only one value for preset white balance at a time; the
existing value is overwritten when a new value is measured or copied. Mea-
suring a new value for white balance automatically sets Preset to Measure.
Measuring a Value for White Balance
1 Place a neutral gray or white object under the lighting that will be used in
the fi nal photograph. In studio settings, an 18% diffusion panel can be
used to make the reference object appear gray.
2 Select Measure in the Preset menu ( 55) or
press the WB button and rotate the main com-
mand dial until
is displayed in the control
panel. White balance will be set to the last
value selected for preset white balance; if no
previous value exists, white balance will be set
to 5,200 K, equivalent to Dir. sunlight.
Measuring White Balance
Preset white balance can be measured in P, S, A, and M modes. In these modes,
exposure is automatically increased by one EV to ensure accurate results. In mode
M, optimal results can be obtained by setting exposure to ±0 EV as indicated by the
electronic analog exposure display.
