AThe Shooting Menu

White balance can be selected using the White balance option in the shooting menu (0 176), which also can be used to fine-tune white balance (0 92) or measure a value for preset white balance (0 94).

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 IFluorescent option can be used to select the light source from the bulb types.

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
