GIMP stands as an acronym for GNU Image Manipulation Program and was known earlier as the General Image Manipulation Program sired by Spencer Kimball & Peter Mattis. GIMP is one of the most powerful image manipulation software under the GNU/Linux and Unix needs but it also comes for Windows and Mac.
Just like Adobe Photoshop, GIMP is also a raster editor. No wonder that users who want to edit photographs and are looking for image manipulation love this software that comes open-source category and is free of cost.
Photo retouching, image composition and image authoring are some of the tasks that users can perform using GIMP. One of the striking feature of GIMP is that it can be used by starting users and also by professional artists: it can be used simultaneously as an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, and simply a paint program.
