Depending on the mode you selected in the previous step, adjust the controls to alter your
matte:
•
In Scrub Boxes mode, drag any side of the outer graph in the Chroma control to alter the
range of hue and saturation contributing to the matte’s edge softness (transparency around
the edges of the key).
Note: In Scrub Boxes mode, you can also drag the two lower handles of the Luma control to
alter the range of lightness and darkness contributing to the matte’s edge softness.
•
In Manual mode, drag any side of the outer graph in the Chroma control to alter the range of
hue and saturation contributing to the matte’s edge softness. Drag any side of the inner graph
to alter the range of hue and saturation contributing to the matte’s tolerance (core softness).
Drag in the center of the inner graph to rotate the graph to a new position in the color wheel.
Note: In Manual mode, you can also drag any of the four Luma control handles. The two
upper Luma handles alter the range of lightness and darkness contributing to the matte’s
tolerance (core transparency); the two lower handles alter the range of lightness and darkness
contributing to matte’s edge softness.
