Canon Optura Instruction Manual page 50

Setting the white balance manually will probably work better
than auto white balance when shooting:
E
Subjects with one dominant color, such as sky, sea or forest.
Close-ups
In rapidly changing lighting conditions
In places lit by certain types of fluorescent or mercury vapor
lights.
Notes:
• Turn the digital zoom off (if neccessary) to set a more accurate white balance.
• If the lighting conditions change, reset the white balance by first returning to the
AUTO setting, and then reselecting SET.
• Try to record with light from a single source. Correct white balance cannot be
obtained for two types of lighting at once.
• You cannot set the white balance manually when the program selector is set to
the [ (Easy Recording) program.
• When the program selector is set to the [ (Easy Recording) program or the
POWER switch is set to the OFF position, the white balance setting returns to
the AUTO.
• When the standby lever is set to LOCK without changing the program selector,
the current white balance setting remains in the memory (except in the Negative-
Positive Conversion program).
