I mainly do post, but I can't stand being in front of a computer all day so I do production as well.
On set, I like to do lighting as well as serving as assistant camera, dolly grip and digital imaging technician. I build grip and camera support equipment, including stereoscopic 3D rigs and motion control rigs.
In post, I do visual effects and color. I frequently serve as online or finish editor to bring projects to final delivery, as well as doing creative editorial. I mainly use Final Cut, Apple Color, and After Effects, supported by Silhouette and Imagineer's Mocha, Mokey and Monet. I also work in Nuke, pfTrack, Maya and Houdini.
