WHITE BALANCE
This function allows the ability to adjust the color temperature, based on colors being
emitted from different light sources. Illumination is generally referred to as color tem-
perature, which is represented in a measurement of kelvin (K).
From the main menu, scroll to WHITE BAL and select one of the 4 following
modes using the Left or Right buttons.
► ATW (a

More accurate then ATW, but has to be reset manually when there is a
change in ambient color temperature.
Notes
• WHITE BALANCE may not work properly under the following conditions:
1. When the color temperature of the environment surrounding the subject is
out of the control range (ie. clear sky or sunset).
2. When the ambient illumination of the subject is dim.
3. If the camera is directed towards a fluorescent light or is installed in a place
where illumination changes dramatically, the WHITE BALANCE operation
may become unstable.
