CHAPTER 6
The COLOR Workl ow
6.1 Overview
In this topic “color” refers to combinations in imagery of various intensities
of portions of the visible spectrum. So in this topic, the term “color” includes:
• black and white levels
• exposure
• l ares
• highlights
• rel ections.
In 2D and 3D, the color is known as a color space. Examples of color spaces
includes:
• Rec709 for television
• DCI P3 for digital cinema
• YUV for certain color pipelines.
There are currently no 3D-only color spaces; 3D shares color spaces with
2D. 3D color can be a self-contained workl ow or part of a Finishing or DI
workl ow. As with geometry and depth workl ows, unplanned forays into
technical i xes can eat into resources intended for creative grading. Since 3D
depends on two images acquired through two different image paths, it is
not surprising that L and R have different color features. If you are familiar
with 2D post color processing, you will have no problem getting up to speed
in 3D post color.
6.2 Types of Color Work
As in 2D post, 3D color consists of creative grading and technical correction .
We use the term color correction for the group of tasks that teams use to prepare
footage for creative grading. In color grading , teams manipulate imagery to
