To understand how these controls work, you could view the node attached to a gradient
background in Waveform mode and observe how different adjustments modify the output.
Output Space
Output Space converts the gamut to the desired color space. For instance, when working with
linearized images in a composite, you place the Gamut node just before the Saver node and
use the Output Space to convert to the gamut of your final output file. You leave this setting at
No Change when you want to remove gamma using the Source Space control.
NOTE: When outputting to HD specification Rec 709, Fusion uses the term Scene to
refer to a gamma of 2.4 and the term Display for a gamma of 2.2.
Remove/Add Gamma
Select these checkboxes to do the gamut conversion in a linear or nonlinear gamma, or simply
remove or add the applicable gamma values without changing the color space.
Pre-Divide/Post-Multiply
Selecting this checkbox causes the image’s pixel values to be divided by the Alpha values prior
to the color correction, and then re-multiplied by the Alpha value after the correction. This helps
to avoid the creation of illegally additive images, particularly around the edges of a blue/green
key or when working with 3D-rendered objects.
Settings Tab
The Settings tab in the Inspector is also duplicated in other Color nodes. These common
controls are described in detail at the end of this chapter in “The Common Controls” section.
Hue Curves [HCV]
The HueCurves node
Hue Curves Node Introduction
The Hue Curves node allows you to adjust the color in an image using a series of spline curves.
Splines are provided to control the image’s hue, saturation, and luminance as well as each
individual color channel. An additional set of curves allows you to apply suppression to
individual color channels.
