About Photoshop


Adobe Photoshop, or simply Photoshop, is a graphics editing program developed and published by Adobe Systems. It is the current market leader for commercial bitmap and image manipulation software, and is the flagship product of Adobe Systems. It has been described as "an industry standard for graphics professionals" and was one of the early "killer applications" on the Macintosh, later also for MS Windows.
Adobe's 2003 "Creative Suite" rebranding led to Adobe Photoshop 8's renaming to Adobe Photoshop CS. Thus, Adobe Photoshop CS4 is the 11th major release of Adobe Photoshop. The CS rebranding also resulted in Adobe offering numerous software packages containing multiple Adobe programs for a reduced price. Adobe Photoshop is included in most of Adobe's Creative Suite offerings.
Photoshop's popularity, combined with its high retail price, makes Photoshop's piracy rate relatively high.[3] Adobe countered by including SafeCast DRM starting with Adobe Photoshop CSEarly history Photoshop 1.0.7 running in System 6.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 display. This program, called Display, caught the attention of his brother John Knoll, an Industrial Light & Magic employee, who recommended Thomas turn it into a full-fledged image editing program. Thomas took a six month break from his studies in 1988 to collaborate with his brother on the program, which had been renamed ImagePro.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; a "total of about 200 copies of Photoshop were shipped" this way.
During this time, John traveled to Silicon Valley and gave a demonstration of the program to engineers at Apple and Russell Brown, art director at Adobe. Both showings were successful, and Adobe decided to purchase the license to distribute in September 1988 While John worked on plug-ins in California, Thomas remained in Ann Arbor writing program code. Photoshop 1.0 was released in 1990 for Macintosh exclusively
Photoshop works on computer systems like Windows and Mac. The software is made by the company Adobe. There is also a version named Photoshop Elements, made for the home user that does not want to buy the full version that is more expensive.
The current version is Photoshop CS4, which was released in 2008.
A Computer is a machine that changes information according to well-specified rules. Computers have existed for much of human history. Examples for early computers are the astrolabe and the abacus. Modern computers have changed since: they are able to control traffic lights, cars or locks. Most modern computers can be used to play music or video. The basic principle is still the same though: The computer has a set of rules, usually called an algorithm. Based on these rules it changes information.
A person uses a computer by telling it to do things, like playing movies or going to Wikipedia. Computers do not know English, so people must tell their computers to do things by speaking the computer's language. Programmers speak the computer's language, and use it to write programs that tell the computer what to do. Normal people use the programs that a programmer wrote to tell the computer what to do.
Computers can do anything that someone can tell them to do. Computers are able to solve mathematical problems because a programmer has told them how to solve math problems. Because computers are very fast, modern computers can solve billions of math problems per second. Computers are used to control factories, which used to be controlled by
