Sony pictures image works' Pete Travers talks "wonderfood" VFX in Cloudy 2

Things I learned

•Pete Travers joined image works in 1999 to supervise effects animation on Hollow man

•Pete worked on Zathura, The Aviator, The Haunted Mansion, The Matrix reloaded, The Lord of the Rings: The Two towers, Stuart Little 2 and Harry Potter and The Sorcerer's Stone

•He holds a degree in Mechanical Engineering from Worcester Polytechnic Institute

Opinion

•Live action and animated films are completely different, you need lighters, effect animators, etc. for both but in animated features you make every pixel

Question

•if you are working with pixels in animation what do you work with in live action films?
