4.8.8 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 oversaturation.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.
Press the COLOR button and press the NEXT button until the item
PROTECT
is shown. Switch
this item on.
In the camera menu, navigate to the
CREATIVE CONTROL > COLOR > COLOR ADJUSTMENT >

COL PROTECT
menu and switch on the item
COL PROTECT
.
4.8.9 Secondary color correction
Secondary color correction is used to adjust hue, saturation and luminance of partial areas of
the color spectrum of the image. Typical applications include live sports or news productions.
Depending on your camera model, 2 or 6 color areas can be set up and corrected at the same
time.
