Using the Custom White Balance

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.

reading for the following situations that are difficult for the [] (Auto)
setting to detect correctly.
• Shooting close-ups (Macro)

• Shooting with a particular source of light (such as a mercury-vapor
lamp)
