Photoshop is a popular image changing software package. It is widely used by photographers for photo editing (fixing colors, reducing noise, adding effects, fixing brightness/contrast) and by graphic designers and Web designers to create and change images for web pages. Version Photoshop CS6 was launched on April 23 2012.
Photoshop works on computer systems like Windows and Mac. The software is made by the company Adobe. A simpler version named Photoshop Elements is made for home users who do not want to buy the more powerful, more expensive full version. Photoshop Express, a free version, is even more limited.
