Most of us know "Photoshop" right? The software that was developed by Adobe. As I remember, I had used Photoshop 7.0 before and then started to use the CS version. Can you imagine when a Photoshop Experts was asked to use Photoshop 1.0?, the first version ever. Let's see their reaction on the video below and at the same time I would like to wish Happy 25th anniversary of Adobe Photoshop. May you will live longer!!!
