Using the Black Gloss control may permit the Matte Density control to be set to a lower level.
Readjust Matte Density control after you adjust Black Gloss control to insure that both controls
are set as low as possible, without permitting print-through in the FG subject.
Warning: Advancing this control too far can cause hard, dark edges around foreground subjects.
3. Green Density: (Blue Backing)
This control is a "fine tuning" control for the density of
green colored FG objects
(G > B, R) in the
generation of the matte signal. It can help eliminate dark edges on green objects without affecting
the edges of neutral colored objects (white, gray).
The Green Density control may be interactive with the Matte Density control, depending on the
colors of FG objects. In some cases, readjusting this control might be necessary.
Warning: Reducing this control too much can cause print-through in green foreground objects.
4. Red Density: (Blue Backing)
This control is a "fine tuning" control for the density of red colored FG objects (R > B, G) in the
generation of the matte signal. It can help eliminate dark edges on red objects without affecting
the edges of neutral colored objects (white, gray).
The Red Density control may be interactive with the Matte Density control, depending on the
colors of the FG objects. In some cases readjusting the Matte Density control might be
necessary
.
Warning: Reducing this control too much can cause print-through in reddish foreground objects
NOTE:
For Green backing the last two controls become:
7. Blue Density
8. Red Density
For Red Backing the last two controls become:
7. Green Density
8. Blue Density
5. Shadow Noise
The Shadow Noise control is a manual override for an automated circuit, which reduces noise in
the matte signal that processes both FG and BG images. This noise is particularly noticeable in
the shadow areas of the matte signal.
Turning the Shadow Noise control to below the default setting of 75% can improve the noise
reduction while simultaneously increasing the density of the shadows cast by FG objects. In most
situations, the Shadow Noise control is left at its default setting. In addition to noise reduction,
the Shadow Noise control can minimize the effect of glare on the floor, in situations where the
backing is extended to cover the floor.
Use this control to reduce noise in shadows and glare areas.
6. BG Level Balance
Use this control to override the automatic setting of the Background level as turned on by the
matte, based on where the backing color was selected. Decreasing this control can enhance the
appearance of fine foreground detail but will darken the background image and increase "visual
noise". Increasing the control can remove "visual noise" and brighten dark edges.
