Much like Google, Photoshop has transcended its original name and become a verb.
The art of photo manipulation is now only ever known by one word: Photoshopping
Perhaps what's most amazing about this demo of the first ever version, is that so much of it is so familiar - in that it's all still there in the latest CS4 version.
At first the mono splash screen makes you think that this will be just a look at a painting program, but John Knoll - one of the original Adobe dev team - quickly shows off some of Photoshop's most innovative and enduring tools.
Can you imagine what people must have thought when they saw this 20 years ago?
Happy birthday Photoshop.
