Adobe Systems' commercial software for editing and manipulating digital photographic images
Adobe Photoshop was first released by Thomas and John Knoll in the summer of 1988. At that time, it ran on System 6.0.3 and Window 3.x. Since then, Photoshop has become very important in the graphics design and photography industry. Photoshop was updated on May 3, 2011 to CS5 (version 12.1 or 12.0.4). On March 21, 2012, a preview of CS6 was released.
