Abstract: Accurately representing digitally generated imagery on print film has historically been difficult due to the differences between an inherently stable digital system and an inherently unstable photochemical system. There are many points in the color pipeline that are variable and if not properly identified and addressed, produce unpredictable results. By digitally representing color as device-independent linear-light values, functions can be created that define a particular output devices' response to those values and inverse functions then applied on output to compensate. In practice, all linear-light values cannot be represented by a cathode ray tube (CRT) or print film, so the output functions must be balanced so that the deficiencies of one device are compensated for by the other. In the print industry, this is called “proofing,” and while the output devices may differ in nature, the concept is valid and can be successfully applied to film output.

bio
Jonathan Egstad has been involved in digital compositing and color technology for over 10 years and has worked on 12 feature films as a compositor and supervisor. In 2002, he was awarded an Academy Technical Achievement Award for helping develop the NUKE-2D compositing software, now in its fourth generation. Educated in film and television production at Fitchburg State College in Massachusetts, Egstad spent four years working in video post-production engineering before joining Digital Domain in 1993.
