01 / The Detroit story
The Detroit story
John Knoll was born in Ann Arbor in 1962 and grew up there, attending Huron High School, before heading to the University of Southern California's film school. He joined Industrial Light & Magic in the 1980s. In 1987 his older brother Thomas, a doctoral student at the University of Michigan, wrote a program on his Macintosh Plus in Ann Arbor to display grayscale images; John saw its potential for film work, pushed him to add image-editing tools and a proper interface, and sold the distribution license to Adobe in 1988. The result was Photoshop, which changed photography, design and filmmaking; the brothers received a Scientific and Engineering Academy Award for it in 2019. At ILM Knoll supervised effects for the Star Wars prequels and the 1997 special editions, won the visual effects Oscar for Pirates of the Caribbean: Dead Man's Chest, and pitched the story that became Rogue One (2016). He is ILM's chief creative officer.
