COLOR cameras only.  


Description


White Balance defines the color temperature of the light source.  Calibrations are performed  for 3200ºK (incandescent), 5000ºK (daylight 1) and 6500ºK (daylight 2).  The camera uses this information to select from one of a number of possible color correction matrices. Turning the White Balance off disables the color correction.  For more information refer to the Image Processing - Color Correction topic.


Minor variations in coloring can be adjusted with the White Shading feature.


When the White Balance control is set in Auto Mode, it will control the White Shading feature.  This allows software that is not IIDC v1.31 compliant to control white shading.
