Part One Here
Alan Chan, Senior Technical Director at Sony Pictures Imageworks, spoke on lighting, rendering and compositing.
Unfortunately, a lot of this was over my head. Above that, there were technical difficulties about half way thru his presentation that took a while and I wound up needing to leave before he finished.
As with David Schaub, he used a lot of examples from his work ("Beowulf") which was very cool to see the before and afters, etc.
