Taking Photographs-White Balance White Balance Keeping Colors True The color of 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 information from the 1,005-pixel RGB sensor, LBCAST image sensor, and ambient light sensor 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. The following options are available: Option Approximate color temperature Description Auto 3,500- 8,000 K Color temperature measured using 1,005-pixel RGB sensor, LBCAST image sensor, and ambient light sensor and white balance adjusted automatically. For best results, use type G or D lens. With SB-800 Speedlight, white balance reflects conditions in effect when Speedlight fires. Incandescent 3,000 K Use under incandescent lighting. Fluorescent 4,200 K Use under fluorescent lighting. Direct sunlight 5,200 K Use with subjects lit by direct sunlight. Flash 5,400 K Use with Nikon Speedlights. Cloudy 6,000 K Use in daylight under overcast skies. Shade 8,000 K Use in daylight with subjects in the shade. Choose color temp. 2,500- Choose color temperature from list of values 10,000 K ( 56). White bal. preset Use subject, light source, or existing photo- - graph as reference for white balance ( 57). Auto white balance is recommended with most light sources. If the desired results can not be achieved with auto white balance, choose an option from the list above or use preset white balance. In auto and preset modes, the camera uses "through-the-lens" (TTL) white balance measurement to ensure that white balance is set correctly even when the camera and subject are under different lighting. 51
