Black Balance Adjustment
Correct adjustment of the black balance is important
for optimum operation of a video camera. It is
necessary when using the camera for the first time or
after a significant period out of use, and also when
there has been a sudden change in temperature.
The adjustment value is saved in memory, and
readjustment is not normally necessary after powering
the camera off or simply when lighting conditions
change.

and release.
