36: Camera, Site tower, Wed 27-Nov-2002 11:24:14 MST, Camera white balance documentation
From the help page for the Axis camera:

White Balance

White balance can be described as the reference color against which all other
colors in an image are compared. The resident white balancing system in the 
AXIS 2420 automatically detects white colors in any image and uses these
intelligently as a reference for other colors. From the drop-down list,
select a suitable balance setting for your camera's local environment.
The available white balance options are described below:

    * Automatic Normal:  Appropriate across the entire color bandwidth, this
automatic setting causes the AXIS 2420 to search for a white reference area
within the image, and all other colors are then adjusted proportionally.
Generally suitable for most environments filled with both artificial white
light, and sunlight.
    * Automatic Narrow: This setting causes the AXIS 2420 to search for a
white reference area in the image using narrow limits of the color range.
All other colors are adjusted proportionally. The automatic color adjustment
is turned off if an appropriate white reference area can not be identified.
    * Automatic Wide: This setting causes the AXIS 2420 to search for a
white reference area in the image, using no limits at all.  All other colors
are adjusted proportionally. This setting gives natural colors in most
environments.
      Note: In environments that do not contain white areas, another color
will be defined as white; i.e. a red object that covers the entire image
will appear as gray.
    * Automatic Fast: The same as Automatic Wide (described above),
but with faster adjustment time.
    * Indoor Light Bulbs: Fixed color adjustment; ideal for a room with
some artificial light other than fluorescent lighting; for example, areas
illuminated using standard light bulbs. Good for normal light temperatures
up to 3200K.
    * Indoor Fluorescent 1: Fixed color adjustment; good for fluorescent
tube light with color temperatures of 4200K
    * Indoor Fluorescent 2: Fixed color adjustment; good for fluorescent
tube light with color temperatures between of 4700K
    * Outdoor: General fixed color adjustment that is appropriate for
outdoor applications under good skylight (color temperatures of 6300K).

Note: In certain situations, the white balancing system will not operate
effectively. Problems generally occur if the image does not contain any
white color at all, or if the dominant color is something other than white.
In these circumstances, the AXIS 2420 can erroneously base the white balance
on another visible color in the image, and consequently, the colors may be
distorted: a pale background picture with foreground objects of an acute
reddish or blue hue are very symptomatic of this condition, and in such
cases we recommend that you operate the AXIS 2420 in a fixed white balance
mode.


34: Camera, Site tower, Tue 26-Nov-2002 11:16:16 MST, color balance on axis camera

Using a color balance of "outdoor" on the axis camera gives us
green snow.  Yesterday, Nov 25, at about 4 pm I set the color balance to
"automatic normal".  Things look a bit better, I'll wait a bit
before trying others, like automatic narrow and automatic wide.

Uploaded the latest firmware, version 2.32 to the 2420 axis camera.
(Had to re-try it several times.  Disable the operational program.
Also do a power cycle just before doing the upload, it seems to help).
