User Manual

Inputs
There are two Inputs on the Light Trim node: one for the 2D image and one for the
effects mask.
–
Input: The orange input is used for the primary Log 2D image that gets its exposure
adjusted.
–
Effect Mask: The blue input is for a mask shape created by polylines, basic primitive
shapes, paint strokes, or bitmaps from other tools. Connecting a mask to this input
limits the exposure change to be within the pixels of the mask. An effects mask is
applied to the tool after the tool is processed.
Basic Node Setup
The Light Trim node is placed after a LOG clip but before the Log clip is converted by a
Cineon LOG node.

When selected, the Lock RGBA control collapses control of all image channels into one slider.
This selection is on by default. To manipulate the various color channels independently,
deselect this checkbox.
Trim
This slider shifts the color in film, optical printing, and lab printing points. 8 points equals one
stop of exposure.
