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:

Preset
Measure	Set
Use photo

—White Balance

Method	Description
Measure	Neutral gray or white object is placed under lighting that will be used
white balance	in final photograph and white balance is measured by camera.
Copy from	White balance value is copied from photo taken with D70 (if desired,
existing	source picture can be RAW image modified using white balance ad-
photograph	justment option in Nikon Capture 4 version 4.1 or later).

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 final 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.
