White Balance
What is White Balance?
The human eye can perceive a white object
as white, regardless of the lighting
conditions. With video cameras, however,
the colour temperature of the light source
may cause the colour of the recorded
picture to be different from the actual colour.
White balance is the adjustment made,
when recording, to obtain natural whites
and colours under a variety of light
sources. The camera has 2 systems for
white balance adjustment; auto and lock.
Explanation:
Colour temperature, measured in degrees Kelvin
(K), indicates the relative redness or blueness of
a light source and is not directly related to
brightness. A light source with a red cast has a
low colour temperature, whereas a bluish light
source has a higher colour temperature.

Auto White Balance
Auto white balance is set automatically when
camera is turned on, to make white balance
adjustment for normal indoor and outdoor
conditions.
Subjects Not Suitable for Auto
White Balance 4
s
a
Auto white balance may not work well in the
following instances, and white balance lock will
probably give you better results:
• Subject with one dominant colour, such as
sky, sea or forest.
• Subject for a macro recording, such as a
close-up of a flower.
White Balance Lock
Use white balance lock when you shoot
subjects not suitable for auto white balance.
• White balance lock also works without using a
white object (see p. 46). Set the power zoom
to wide- angle end and press lAWBI/LQCK
button to adjust for the scene. However, this
is not suitable for scenes with one dominant
colour or for macro recording.
Notes:
•
White balance lock clears automatically when in playback mode or the camera is turned off.
• Reset white balance again if the light source changes during white balance lock.
• Use white balance lock even under normal lighting conditions to achieve a more precise colour balance.
