A calibration error may occur under extremely bright light sources, especially with flash units. If an error occurs, a message appears on the monitor and the white-balance indicator is yellow. Repeat the procedure by recalibrating using a gray card as a reference target to reduce the intensity of the illumination.

COLOR TEMPERATURE

 

White balance can be set to a known color temperature

 

of a light source or set to the color temperature

 

determined by a color meter. With the white balance dial

 

in the color temperature (K) position, press the white-

 

balance button to open the setting screen.

Magenta/Green compensation

 

Color temperature refers to the color of the light emitted from a blackbody radiator at a specific temperature given in degrees Kelvin. This is an accurate way of measuring light from continuous-spectrum sources such as the sun and incandescent or tungsten light bulbs.

However, color temperature alone can be inaccurate with discontinuous-spectrum sources such as fluorescent. The magenta/green compensation scale allows adjustments to compensate for this problem. The increment on the scale is equivalent to approximately 5CC; M3 would be 15CC magenta.

For information on light sources, see page 69.
