In this 18 minute documentary, the founders of Adobe Photoshop - John Knoll, Thomas Knoll, Russell Brown, and Steve Guttman - tell the story of how an amazing coincidence of circumstances, that came together at just the right time 20 years ago, spawned a cultural paradigm shift unparalleled in our lifetime.

It’s almost hard to believe the program is 20 years old. I remember using a very early version of it that had no layers, no history and each variation of an image had to be saved as a separate file. There are some surprising references to Macintosh, ILM, Pixar and James Cameron that relate to the birth of Photoshop.
