Note
During the auto-white measurement process the iris is set to Auto and 90% and knee is
switched off.
Black balance is not necessary because black level is automatically adjusted by the camera’s
internal video circuits.
Saturation
Adjust the saturation level to increase or decrease color of the picture. Saturation values
below 100% decrease colors while values higher than 100% increase colors.
In the camera menu, navigate to the
production Setup > Color >Saturation
item and
adjust the level.
Color Gamut
The camera can operate using two different color gamuts:
In the camera menu, navigate to the
Production Setup > Color > Color Gamut
item and
select REC709 (for default HDTV color gamut) or REC2020 (for extended color gamut). In
HDR operation LMS is supported in addition to REC709 and REC2020.
Color Protect
When very bright and saturated colored lights are used, predominant colors may clip. This
results in fully saturated areas with no detail. This phenomenon occurs especially in blue
and magenta color ranges.
The Color Protect function restores luminance levels without affecting color over-
saturation. It prevents non-dominant colors from decreasing below black level so much of
the details in the picture are still maintained. If a dominant color saturates, Color Protect
gradually decreases its influence in the picture.
In the camera menu, navigate to the
Production Setup > Color > Color Adjustment >
Col Protect
menu and switch on the item
