    Adobe Photoshop, or commonly called Photoshop, is an image editor software made by Adobe Systems which is devoted to photo/image editing and effect creation. This software is widely used by digital photographers and advertising companies so it is considered the market leader for image/photo processing software, and, together with Adobe Acrobat, is considered the best product ever produced by Adobe Systems. The eighth version of this application is called Photoshop CS (Creative Suite), version nine is called Adobe Photoshop CS2, version ten is called Adobe Photoshop CS3, the eleventh version is Adobe Photoshop CS4, the twelfth version is Adobe Photoshop CS5, the thirteenth version is CS6, and the latest version is Adobe Photoshop CC (Creative Cloud). Photoshop is available for Microsoft Windows, Mac OS X, and Mac OS; version 9 and above can also be used by other operating systems such as Linux with the help of certain software such as CrossOver.

   Development in 1987, Thomas Knoll, a PhD student at the University of Michigan, began writing a program on his Macintosh Plus to display grayscale images on a monochrome screen. This program, called Display, caught the attention of his brother John Knoll, an employee at Industrial Light & Magic, who recommended Thomas converting his program to a full-fledged image editing program. Thomas took a six month break from studies in 1988 to collaborate with his brother on the program, which had been renamed ImagePro.[1] After that year, Thomas changed the name of the program to Photoshop and worked briefly with scanner manufacturer Barneyscan to distribute copies of the program with slide scanners; “a total of about 200 Photoshop copies have been shipped” this way.[2] During this time, John traveled to Silicon Valley in California and gave demonstrations of the program to engineers at Apple Computer Inc. and Russell Brown, art director at Adobe. Both demonstrations were successful, and Adobe decided to purchase a license to distribute in September 1988.[1] While John worked on plug-ins in California, Thomas remained in Ann Arbor writing code. Photoshop 1.0 was released in 1990 specifically for the Macintosh.
