The camera can store only one value for preset white balance at a time;
the existing value will be replaced when a new value is measured. Note
that exposure is automatically increased by 1 EV when measuring
white balance; if M Manual is selected for Exposure mode, adjust
exposure so that the exposure indicator shows ±0 (

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  wave-
lengths.  While light sources with a color temperature in the neighbor-
hood 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 follow-
ing color temperatures (all figures are approximate):
