3.3.6 WBC MODE
A digital camera needs to find a reference colour temperature, which is a way of
measuring the quality of a light source, in order to correctly calculate all the other
colours. The unit for measuring this ratio is degrees Kelvin (K). You can select one of
the white balance control modes depending on the conditions. The following table
shows the colour temperature of some light sources.
Light source Colour temperature in K
Cloudy sky 6,000 to 8,000
Noon sun and clear sky 6,500
Household lighting 2,500 to 3,000
75 watt bulb 2,820
Candle flame 1,200 to 1,500

In this mode, the white balance function works within its colour temperature
range. This mode computes the white balance value output using colour
information from the entire screen. It outputs the appropriate value using the
colour temperature radiating from a black subject based on a range of values
