Adobe is enjoying the 20th anniversary of the premier photo editing application Photoshop, and a new documentary has surfaced where the founders of Photoshop discuss their creation.

In this 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, spawned a cultural paradigm shift unparalleled in our lifetime.

It’s a big video, 830mb if you download it.  Watch it online at AdobeTV.  Enjoy.
