By default, when a channel is opened, the isolation is set to a 60
degrees vector width, centred about the R, G, B, Y, C and M key that
was chosen. The lower saturation threshold is set slightly above zero
to exclude black and white areas from the isolation. The full luminance
range is included in the isolation. By default, the thresholds of hue,
saturation and luminance isolation are softened slightly. The softness
of all these thresholds can be independently adjusted. However there is
only one physical control for softness. Whenever one of the above
threshold controls is adjusted, the softness of this threshold is
automatically assigned to the seventh control on the DCP panel.
To make a channel work on all colours, simply press the EXPAND
key. This is the key below GRAB on the DCP control
panel.
By default, the isolation occurs over the full picture area. However, the isolation can be limited to particular areas of the picture by using the region controls available for each channel. A double press of the button next to the ball on the DCP panel, will set the area to a small rectangle. Use of Mask mode will ease adjustment of this region.
The region position can be adjusted using the track ball on the DCP control panel. The small button next to this track ball toggles control of the region between size and position. Press and hold this button to reset the region to be full screen. Then all parts of the picture will be in the isolation. Double press this button to set a default region. (A tall rectangle)
