Keeping Colors True

The color of the light reflected from an object varies with the color of the light source. The human brain is able to adapt to changes in the color of the light source, with the result that white objects appear white whether seen in the shade, direct sunlight, or under incandescent lighting. Unlike the film used in film cameras, digital cameras can mimic this adjustment by processing images according to the color of the light source. This is known as "white balance." For natural coloration, choose a white balance setting that matches the light source before shooting. When the mode dial is set to P, S, A, or M, white balance can be selected from the following options:

13 Speedlights Connected via a Sync Cable

Auto white balance may not produce the desired results when the AS-15 accessory shoe adapter is used to connect optional Speedlights via a sync cable. Use preset white balance or set white balance to Flash and use fine tuning to adjust white balance.

When WB bracketing is selected for Custom Setting 12 (BKT set), the camera will create several images each time the shutter is released. White balance will be varied with each image, "bracketing" the value currently selected for white balance.
