My demo reel above demonstrates some of the work I've done over the years at various studios. I worked on lighting, compositing, and some look development for these shots, primarily rendered with renderman, arnold, and nuke software packages.
Digital lighting is both technical and artistic, and requires knowledge of traditional cinematography plus knowledge of the behavior of light and materials. In the reel above, I placed digital lights very deliberately in the scenes to create an emotional mood, even before the viewer has understood the story point. With the correct lighting, I can direct the viewer's eye, shape the objects, create depth in the scenes, and acheive special effects (like sparks).
One technical aspect of digital lighting is balancing artistic quality with rendering time and the director's vision. This requires great communication and people skills to understand and achieve what the director wants. But it also requires the understanding of how to translate that direction into quantifiable light properties and surface characteristics for objects used in the rendering software.
Each scene is synthesized into a series of image files by a rendering software simulation. As a Lighting Technical Director, I adjust all the parameters of the scene to control the software and generate images with the desired level of quality and realism in a reasonable amount of time. These images are then printed onto film and/or assembled into a digital movie.
