Coloring a New Dimension - Translating 2D color grading to a 3D environment.

About a year before Colorist Stefan Sonnenfeld here atCompany 3performed the color-grading work on Disney's 3D featureG-Force, a group of us under him started preparing for the industry's movement toward 3D production. The specifications of a 3D image as it's projected in a theater are very different from those of a 2D image, and that goes far beyond the obvious fact that there are two images (the left and right eye) being put on a screen simultaneously. The projector brightness is considerably less; the screen reflectivity, at least in the RealD process we used for G-Force, is considerably more; and the glasses people wear in the theaters have a tint to them. Those factors alone considerably alter the way color and contrast must be treated between 2D and 3D presentations. More:
