Adobe Photoshop is a digital image editor developed and published by Adobe Systems for Windows and Mac. It is a powerful software capable of maniplulating images for print or web, and is used by a wide variety of creatives from photographers to artists.


Adobe Photoshop was created in 1988 by Thomas and John Knoll. Since then, it has become the most used graphics editor within the industry. It uses several color models including RGB, CMYK, Lab color Space, spot color, and duo-tone. Photoshop has vast support for graphic file formats but also uses its own PSD and PSB file formats. It has limited abilities to edit or render text, vector graphics, 3D graphics, and video. Photoshop's feature set can be expanded by Photoshop plug-ins: programs developed and distributed interdependently of Photoshop that can run inside it and offer new or enhanced features.

Early History

In 1987, Thomas Knoll began writing a program on his Macintosh Plus to display grayscale images on a monochrome display[1]. Later that year, Thomas renamed his program Photoshop and worked out a short-term deal with scanner manufacturer Barneyscan to distribute copies of the program with a slide scanner. Photoshop was then showed to Apple and Adobe. Both showings were successful, and Adobe decided to purchase the license to distribute in September 1988.
