Selected Color
This shows the color selected (or registered) by the scrubbing in the viewer while the Fine
Tuning tab is selected.
Fine Tuning Sliders
The color of the scrubbed pixel is registered as a reference color for fine tuning. It is displayed
in the Color swatch. To perform the tuning operation, sample a color region on the image, and
adjust one of the Fine Tuning sliders to achieve the desired effect.
Spill
The Spill slider can be used to remove spill from the selected color region. The more to the
right the slider moves, the more spill is removed. The more to the left the slider moves, the
closer the color component of the selected region is to the color in the original foreground
image. If moving the slider to the right does not remove the spill, resample the color region and
move the slider again.
These slider operations are additive. The result achieved by moving the slider to the right can
also be achieved by clicking on the color region using the Spill(-) operational mode.
Transparency
The Transparency slider makes the matte more translucent in the selected color region. Moving
this slider to the right makes the selected color region more transparent. Moving the slider to
the left makes the matte more opaque. If moving the slider to the right does not make the color
region translucent enough, resample the color region and again move the slider to the right.
These slider operations are additive. The result achieved by moving the slider to the right can
also be achieved by clicking on the color region using the Matte(-) operational mode.
Detail
The Detail slider can be used to restore lost detail. After selecting a color region, moving this
slider to the left makes the selected color region more visible. Moving the slider to the right
makes the color region less visible. If moving the slider to the left does not make the color
region visible enough, resample the color region and again move the slider to the left.
These slider operations are additive. This result achieved by moving the slider to the left can
also be achieved by clicking on the color region using the Detail(-) operational mode.
Replace Tab
The Replace tab allows you to choose between the three methods of color spill replacement as
covered in detail in the Spill Sponge section above. There are three options for the replacement
color when removing the spill. These options are selected from the Replace mode menu.
Replace Mode
Complement: Replaces the spill color with the complement of the screen color.
This mode maintains fine foreground detail and delivers the best-quality results. If
foreground spill is not a significant problem, this mode is the one that should be used.
However, If the spill intensity on the foreground image is rather significant, this mode
may often introduce serious noise in the resultant composite.
