Photoshop Versions

For people who’ve grown up around digital cameras and graphics editing software, it may be impossible to understand how hugely innovative Photoshop 1.0 was when it was first released 21 years ago.

BeforetheadventofPhotoshop,photomanipulation was a laborious process, carried out by piecing together different photographs and/or negatives, double-exposing negatives to achieve a particular effect or when all else failed retouching portions of a developed photograph with ink, paints or airbrushes. Photoshop made photo editing as easy as pressing the “Enter” button on your keyboard.
