The development of Photoshop started in 1987, first by Thomas Knoll and later with his brother John Knoll. The latter worked at the time by Industrial Light & Magic. He put the program as a VFX artist for the film The Abyss. The resulting program they called the display. The next time the program improved the brothers and the first delivery of 200 copies of version 0.87 a year later for the company Barneyscan XP, along with their scanners under the name Image Pro.
Aldus developed at the same time the photo Tyler. Adobe had just met with an agreement for the development of Letraset Color Studio, Adobe's Photoshop as an art director Russell Brown as the better program was discovered. Therefore, in 1988 joined the Knoll brothers and Adobe software for a future contract. Only two years later, in February 1990 Adobe Photoshop S1.0 was published exclusively for the Apple Macintosh. From the start it was intended for processing images that were digitized by a scanner. These devices were at that time still rare and expensive.
Although primarily developed for the processing of print-ready images that were produced with Photoshop images, increasingly, for the World Wide Web. With version S5.5 came out with an additional program called Photoshop Image Ready, the specialized tools for this purpose was made available. These functions were up to version CS2 integrated gradually into the main application.
With the release of Adobe Creative Suite (CS) (2003) designation of Photoshop has changed: in the foreground of the name since then is the membership of each suite (Photoshop CS, Photoshop CS2, Photoshop CS3, etc.), the actual version number ( 8, 9, 10, etc.) is only called in addition.
In April 2005 appeared to Version 9 (CS2), 27 March 2007 version 10 (CS3, the English version on the market since April 16, 2007, the German version since May 15, 2007). The Intregation of Image Ready in the main program has been completed and has since then not as a separate program.
