Editing Viewer LUTs
The viewers are the primary area where composites are assessed, so it’s crucial that they
provide an accurate representation of what the content will look like when it’s played for an
audience. The LUT Editor allows you to customize your viewer’s output to match the gamma
and color characteristics of your eventual playback device, or to test how the current image
looks in a completely different color space, or how it holds up over a range of different
color spaces.
To open any editable viewer LUT option’s Editor:
1 Click the LUT button in the viewer toolbar to enable it.
2 Do one of the following:
Choose Edit from the bottom of the viewer LUT menu.
Right-click in the viewer and then choose LUT > Edit from the contextual menu.
Editing the Fusion View Lookup Table
Similarly to the Color Curves node, the Fusion View LUT Editor uses spline-based color
correction. In addition to the ability to modify the separate color channels, the LUT has Gain and
Gamma sliders. The Gain slider is helpful for temporarily brightening or darkening the viewed
image, allowing easier examination of shadow or highlight detail. The Color Gamma and Alpha
Gamma sliders are used to duplicate the gamma values of the eventual output device. Video
monitors, for example, commonly have a gamma of 1.7, while computer monitors can range
anywhere from 1.6 to 2.2. Alpha Gamma is applied only when viewing the alpha channel of an
image, or when viewing masks.

Editing the Gamut View LUT
The Gamut View LUT Editor lets you choose a Source and Output color space to guide the
viewer transform.
The Remove and Add Gamma checkboxes let you choose to do the gamut conversion with
linear or nonlinear gamma, or they let you simply remove or add the appropriate gamma values
without changing the color space.
