This is a really great lecture from TED about the VFX of Benjamin Button. My wife and I got to see a special screening of the film at Skywalker Sound a couple of weeks ago. After the film was over there was a Q&A with Craig Barron who was the VFX sup for Matte World Digital. He gave some great insight into the development of the cg environments and compositing that MWD provided for the film. Congrats to Craig and his team for the Oscar win last night!
This lecture however focuses on the techniques and processes Digital Domain used in creating the cg Benjamin head for actor Brad Pitt.
