GIMP is an open source graphics design software similar to PhotoShop.
Details
The "GNU Image Manipulation Program" (originally the General Image Manipulation Program) sired by Spencer Kimball & Peter Mattis.
In their own words, "GIMP is our answer to the current lack of free (or at least reasonably priced) image manipulation software for GNU/Linux and UNIX in general."
It is a raster editor, which means that it performs operations directly on the pixels that make up the image, and not a vector editor. Other (proprietary) raster editors include Adobe Photoshop, Jasc Paintshop Pro and the humble Microsoft Paint. An alternative free editor is the KOffice project, Krita. Users wanting to edit photographs will certainly want a raster editor like GIMP. Graphic designers and illustrators may prefer a vector editor depending on their tastes.
Features
Customizable Interface
Each task requires a different environment and GIMP allows you to customize the view and behavior the way you like it. Starting from the widget theme, allowing you to change colors, widget spacings and icon sizes to custom tool sets in the toolbox. The interface is modulized into so called docks, allowing you to stack them into tabs or keep them open in their own window. Pressing the tab key will toggle them hidden.
GIMP features a great fullscreen mode allowing you to not only preview your artwork but also do editing work while using the most of your screen estate.
Photo Enhancement
Numerous digital photo imperfections can be easily compensated for using GIMP. Fix perspective distortion caused by lens tilt simply choosing the corrective mode in the transform tools. Eliminate lens' barrel distortion and vignetting with a powerful filter but a simple interface.
File Formats
The file format support ranges from the common likes of JPEG (JFIF), GIF, PNG, TIFF to special use formats such as the multi-resolution and multi-color-depth Windows icon files. The architecture allows to extend GIMP's format capabilities with a plug-in. You can find some rare format support in the GIMP plugin registry.
Thanks to the transparent virtual file system, it is possible to load and save files to from remote locations using protocols such as FTP, HTTP or even SMB (MS Windows shares) and SFTP/SSH.
To save disk space, any format can be saved with an archive extension such as ZIP, GZ or BZ2 and GIMP will transparently compress the file without you needing to do any extra steps.
