CLIPSTER Edit Tool User Guide
The check box Hold B+W allows you to hold the black and white points
of the image. When it is activated, a gamma correction will be per-
formed between adjusted black and white points. With the check box
deactivated, the black and white points will be disregarded and a gam-
ma correction will be made on the full value range of the image’s color
channels instead.
7.10.5 Color Wheel
To the right of the settings pane you can find a color wheel. It contains
the colors according to their hue and saturation (HSL color space), and
additionally indicates all color components (RGB and CMY). With the
hues set on the rim of the circle, the distance from the circle’s center de-
termines the saturation of the respective color.

Example:
To see the effect of the check box Hold B+W lower the black and
white points of an image, for example, by flattening its contrast (set
to a negative value). Afterwards adjust the gamma of one of the col-
ors with the sliders for gamma.
Once this is set, you can see the effect of the check box in the video
overlay and in an RGB parade immediately (see section “The Video
Scopes” on page 5-3): When activated, a color correction will be per-
formed between the limited black and white points only; when deac-
tivated, the adjusted black and white points will not be observed.
The color distribution in a color wheel is the same as in a vec-
torscope. Further information about this can be found in sec-
tion “The Video Scopes” on page 5-3.
