The visual effects color pipeline starts in the real world, of course. The light from surfaces and light sources are captured by cameras and travels a data path through several “spaces” to the movie screen. The challenge for visual effects is that the real world presents color and light in a totally different way that far exceeds the capacity of our display devices so a degraded version of the original scene must be carefully managed in order to deliver the most realistic version of the original scene to the audience. The real world is not a “color space” in the color science sense, but instead is presented here as the “World Space” where our entire VFX pipeline begins.
