Even though you (usually) don’t see it, Photoshop is used just about everywhere you look. From the billboards you see in the streets to the magazines you read and the movies you watch. Worldwide about 10 million creative minds like photographers, graphic designers, architects, advertisers and publishers use Photoshop every day. Even doctors and 3D artists use Photoshop these days.

Recently the founders of Adobe Photoshop – John Knoll, Thomas Knoll, Russell Brown, and Steve Guttman – came back together to 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.

There are a number of exciting activities going on around the world to celebrate this occasion and here are 3 things for you to do to join the celebration online:

• Photoshop 20^th anniversary site: The site shows you all the innovations in Photoshop since version 1.
• Special Layer Tennis Match, Photoshop 20^th Edition with commentary by John Nack.
• Photoshop 20^th Celebration Tab on Facebook: Add it to your profile page, and share with friends and colleagues.

Happy birthday Photoshop!
