Our favourite photo editing software: Adobe Photoshop turned 20 this week.
Back in 1987, Thomas Knoll, a PhD student at the University of Michigan, started playing with greyscale digital images on a monochrome display. His brother, John, soon joined him and together they came up with the image editing software.
This week, John (now a visual effects supervisor at Industrial Light & Magic) said: ‘It’s endlessly amusing to see how much it has permeated popular culture. It really is everywhere. You can hardly turn around and not see something that was done in Photoshop. And it started out with Tom and I screwing around with it as a hobby. It was the right product at the right time.’
