White Balance Lock
The colour of the subject on the screen tends
to look different depending on the lighting
condition. The VIEWCAM is preset to Auto
White Balance mode, which automatically
adjusts the hue of the picture for the current
lighting condition.
The Auto White Balance may not work properly
for the following subjects. In this case, use the
white balance lock function.
• Subjects with one dominant colour or
subjects against background with one
dominant colour
• Subjects under very bright light source, e.g.
video lights
• Subjects under light source with red hue, e.g.
glow of sunset
• Close-up images of small objects
