SIGGRAPH 96
Courses

28. Digital Color

Full Day / Intermediate


Computers have been used to generate synthetic images since the first SIGGRAPH conference, and to generate color images for nearly that long. But only recently has it become practical to create and reproduce digital images with predictable, accurate color, and easily move images from the SIGGRAPH world into video, film, and print. This course explains the science behind color reproduction, image digitization, and image reproduction in video, film, print, and computer graphics.

Who Should Attend
Hardware and software engineers, system designers, digital cinematographers, and advanced end users, including digital photographers.
