01 / The Detroit story

The Detroit story

Knoll was born in Ann Arbor in 1960, grew up there and studied at the University of Michigan. In 1987, while working on a doctorate in computer vision, he wrote a small program on his Macintosh to show grayscale images on a monochrome screen. His brother John, who worked at George Lucas's Industrial Light & Magic, saw its potential for film effects and pushed him to add features and a proper interface. The brothers licensed the program to Adobe in 1988, and it was released as Photoshop 1.0 in 1990; they sold Adobe full rights in 1995. Thomas remained lead developer through version CS4 and has since worked on Camera Raw, which processes the raw files of digital cameras. In 2019 the brothers received an Academy Award for Scientific and Engineering achievement for Photoshop.
