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 [] (Auto)
setting to detect correctly.
• Shooting close-ups (Macro)
• Shooting subjects of monotone color (such as sky, sea or
forest)
• Shooting with a particular source of light (such as a
mercury-vapor lamp)
