Digitally Adding Blemishes - NYTimes.com February 16, 2012, 5:33 pm With R2-D2 trailing behind, the Bagger stopped in San Francisco for a rare look inside the visual-effects house Industrial Light & Magic, a player this awards season with nominations in the technical categories. You can get a peek in this video. While there were fun mementos from "Star Wars" and other movies with ILM's gee-whiz-how'd-they-do-that stamp, the visit pointed up an interesting anomaly. "In the popular imagination digital filmmaking - animated or live action - is a clean, sterile process, a lot of button pushing and knob tweaking," the Bagger writes. Though there is some truth to that, "in reality animators and effects maestros alike strive to inject humanity, in the form of blemishes and surprises, into their work."
