Combining two nodes using the Layer Mixer set to
Add to create a glowing effect
By adding both treatments together, a hot glow has been created, blowing out the highlights of
the image. Many, many other effects are possible using the different composite modes that are
available. For more information on composite modes, see Chapter 41, “Compositing and
Transforms in the Timeline.”
Adjusting Layer Node Strength Using Key Output Gain
Whether you’re combining overlapping corrections, or mixing different adjustments using
Composite modes, you’ll run into situations where you want to reduce the influence of one
overlapping adjustment relative to the other nodes that are connected to the Layer Mixer node.
This can be accomplished using each overlapping node’s Key Output Gain parameter, located
in the Key palette.
Using the Output Gain parameter in the Key palette
Key Output Gain defaults to 1.00, but lowering this value reduces the strength of that node’s
contribution to the Layer Mixer. Using the previous example, selecting Node 4 (the
high-contrast image used to create the glow), opening the Key palette, and reducing the Key
Output Gain parameter to 0.50 reduces the intensity of the Glow effect by half.
