B) Press the MENUS “
MATTE
” hard button on the left side of the remote panel. Set the Matte controls to
affect the black and gray areas of the matte using these guidelines:
i)
Matte Density:
Use this control to stop print-thru in bright foreground objects.
ii)
Warning: Advancing this control too far can cause hard, dark edges around foreground
subjects.
The following controls are used for finessing or fine-tuning. These adjustments are best seen while
viewing the composited image or toggling back and forth between the matte view and the composite view
by pressing/depressing the VIEW “
MATTE
” hard button on the right side of the remote panel:
iii)
Red Density:
(not available for red backing): Use this control to reduce dark edges from
reddish objects (flesh-tones).
Warning: Reducing this control too much can cause print-thru in
reddish foreground objects.
iv)
Green Density:
(not available for green backing): Use this control to reduce dark edges from
greenish objects (plants).
Warning: Reducing this control too much can cause print-thru in
greenish foreground objects.
v)
Blue Density:
(not available for blue backing): Use this control to reduce dark edges from
bluish objects. (Blue jeans
) Warning: Reducing this control too much can cause print-thru in
bluish foreground objects.
vi)
Black Gloss:
Use this control to stop print-thru in black glossy or dark foreground objects.
Warning: Advancing this control too far can cause dark edges around the foreground subject
and shadows will darken and become opaque.
C) Set the Clean-Up controls to affect the white and gray areas of the matte using the following
guidelines:
These matte controls are used to adjust the white and gray areas of the matte channel. This will
dramatically affect the nature of foreground objects' edges, the opacity of transparent objects, and the
noise in the background image. Use these controls sparingly, as they
WILL
result in the loss of
foreground detail.
As above, these controls are also used for finessing or fine-tuning, and are best seen while viewing the
composited image.
i.
Shadow Noise:
Use this control to reduce noise in shadows and glare areas
. Warning:
Decreasing the control too much will reduce fine detail.
ii.
BG Level Balance:
Use this control to override the automatic setting of the Background level as
turned on by the matte, which is 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 this control can remove "visual noise" and brighten
dark edges
. Warning: Advancing this control too far can cause foreground objects' edges to glow.
iii.
Clean Up LEVEL:
Used to reduce imperfections or small amounts of noise in the backing
.
Warning: Advancing this control too far will result in a "cut and paste" look. Background noise will
be reduced, but foreground detail will also be reduced
.
iv.
Clean Up THRESHOLD:
Used only when the Clean Up LEVEL control has been adjusted. The
Clean Up Threshold control sets the threshold level above which the Clean Up Level control is
applied to the matte signal. In certain cases it can eliminate small screen imperfections without
affecting the density of most shadows, and minimizes the effect of Clean Up Level on FG edges.
D) View the Composite by pressing the VIEW “
MATTE
” hard button in the upper right hand corner of the
remote panel (disabling the Matte view).
