A The Shooting Menu White balance can also be adjusted using the White balance option in the shooting menu (0 224), which also can be used to fine-tune white balance (0 91) or measure a value for preset white balance (0 95). The Auto option in the White balance menu offers a choice of Normal and Keep warm lighting colors, which preserves the warm colors produced by incandescent lighting, while the I Fluorescent option can be used to select the light source from the bulb types. A Studio Flash Lighting Auto white balance may not produce the desired results with large studio flash units. Use preset white balance or set white balance to Flash and use fine tuning to adjust white balance. A Color Temperature The perceived color of a light source varies with the viewer and other conditions. Color temperature is an objective measure of the color of a light source, defined with reference to the temperature to which an object would have to be heated to radiate light in the same wavelengths. While light sources with a color temperature in the neighborhood of 5000- 5500 K appear white, light sources with a lower color temperature, such as incandescent light bulbs, appear slightly yellow or red. Light sources with a higher color temperature appear tinged with blue. The camera white balance options are adapted to the following color temperatures (all figures are approximate): • I (sodium-vapor lamps): 2700 K • H (direct sunlight): 5200 K • J (incandescent)/ • N (flash): 5400 K r I (warm-white fluorescent): 3000 K • I (white fluorescent): 3700 K • G (cloudy): 6000 K • I (daylight fluorescent): 6500 K • I (cool-white fluorescent): 4200 K • I (high temp. mercury-vapor): 7200 K • I (day white fluorescent): 5000 K • M (shade): 8000 K A See Also When WB bracketing is selected for Custom Setting e6 (Auto bracketing set, 0 251), 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 (0 137). 90
