Using the Custom White Balance
You can set a custom white balance to obtain the optimal
setting for the shooting conditions by having the camera
evaluate an object, such as a piece of white paper or cloth,
or a photo-quality gray card that you wish to establish as the
standard white color.
In particular, take a custom white balance reading for the
following situations that are difficult for the
to detect correctly.
Shooting close-ups
Shooting subjects of monotone color (such as sky, sea or
forest)
Shooting with a particular source of light (such as a
mercury-vapor lamp)
