Photoshop is a raster graphics editing software suite made by Adobe that enables users to analyze and modify digital images. Photoshop is considered to be the leading raster graphics editing software as of 2014, and it is used worldwide by photographers and graphic designers alike. The software bundles an abundance of tools and presets that enable graphics to be modified and built on in almost every conceivable way.
Photoshop supports masks, alpha compositing and color models such as RGB, CMYK, spot color, duotone and lab color space. It also supports most image file formats, including its own native project formats, PSD and PSB. Photoshop has the ability to render and edit text, vector graphics, 3D graphics and video.
In 1987 brothers Thomas and John Knoll created Photoshop. The software was initially named Display, then it was changed to ImagePro and finally renamed Photoshop in 1988. Thomas traveled to Silicon Valley the same year to showcase the software to Apple and Adobe. Both showcases were successful, and Adobe decided to buy the distribution licence. The first consumer edition of Photoshop was released February 1990 exclusively for the Apple Macintosh computer. Since then, it has become the industry standard in raster graphics editing. Photoshop is now available for both Microsoft and Apple operating systems.
