This series shows how you can expand the functionality of the Gmask Tracer from Roto tool to Look Development. Part 1 uses the Gmasks as cutouts or “gobos” to control the casting of a 3D light. This allows you to very accurately focus light on various parts of your image. Used with Lightbox, you can apply various grading and effects to these selectives for a great look development experience. This is a different way of thinking compared to traditional Look Development workflows.
