Description
ALC level
-15 to +15
Selects the video level range. A
positive value is more useful for low-
light conditions; a negative value is
more useful for very bright
conditions.
Some ALC adjustment may improve
scene content when Smart BLC is
enabled.
ALC speed
Slow,
medium, fast
Adjusts the speed of the video level
control loop. For most scenes it
should remain at the default value.
