Adjust the Clean Up Balance
control while viewing the composite image on a video monitor. Take
it off its default setting only if it appears to restore some of the softness or fine detail to edges on
the FG subject.
7. BG Level Balance
Use this control to override the automatic setting of the Background level as turned on by the
matte, based upon where the backing color was selected. Decreasing this control can enhance
the appearance of the forefround detail, but will darken the background image and increase
"visual noise". Increasing the control can remove "visual noise" and brighten dark edges.
Warning
:
Advancing this control too far can cause foreground object edges to glow
.
8. Matte Reset
Activating the Matte Reset button restores all matte-setting controls (Matte Density, Black Gloss,
Red Density, Green Density, Blue Density and Shadow Noise) to their default settings. These
default settings could be factory set or user set values. See sec. XLVI for details of setting and
using User Files.
Matte Reset does not sample the backing for new reference color values; it uses the current
values to recalculate backing color suppression and BG 'turn on' parameters. In addition, its
activation has no influence on the rest of the controls, which might have been set by the operator
to values other than their default settings.
