Photoshop is a photo-editing software. It is a popular image changing software package. It was developed in 1987 by the American brothers Thomas and John Knoll. There are two types of graphic software – Vector Graphic and Raster Graphic. This software provides many image editing features for raster (pixel-based) images as well as vector graphics. In technical language, Photoshop is a RASTER graphic software, which means it is used to edit the raster graphics. 

RASTER is a combination of pixels. A group of pixels forms a graphic called Raster Graphics. There are various forms of formats of Raster Graphics – 
 

  • JPEG – Joint Photographic Experts Group
