The GIMP Team - (Open Source)
Process or edit an image is not easy if user do not have the skill unless it is used the right tool and The Gimp is a smart choice for anybody that need to do this.
 The Gimp is a graphic program and one very powerful photo editing. It includes all the tools needed to create drawings and all filters to correct and improve a shot. GIMP can be used by users of various levels as a paint program, an advanced photo editing program, a batch system, a format converter, etc The application has an intuitive interface, a display mode in one window and quickly accessible controls. A module layer organization also facilitates the implementation and the creation of complex compositions.
 
 The number of tools, brushes and filters is impressive and will not disappoint Photoshop users. With a little practice, everything is in great. 
 
 The plug-in screen capture integrated into "file - create" allow the creation of a "screen shot" including the mouse cursor.

 - Separate the activies of saving an image and exporting it, there is now an 'File->Export...' for example
 - Port file plug-ins to new export API which gets rid of many annoying export dialogs
 - Add a simple parser to size entry widgets, images can be scaled to e.g. "50%" or "2 * 37px + 10in"
 - Arrange layer modes into more logical and useful groups
 - Added support for rotation of brushes
 - Make the Pointer dockable show information about selection position and size
 - Get rid of the Tools dockable and move toolbox configuration to Preferences
 - Add status bar feedback for keyboard changes to brush paramaters
 - Add diagonal guides to the Crop Tool
 - New docks are created at the pointer position
 - Add support for printing crop marks for images
 - Move 'Text along path' from tool options to text context menu
 - Change default shortcuts for "Shrink Wrap" and "Fit in Window" to Ctrl+R and Ctrl+Shift+R respectively since the previous shortcuts are now used for the save+export feature
 - Make Alt+Click on layers in Layers dockable create a selection from the layer
 - Allow to specify written language in the Text Tool
Plug-ins:

 - Add "FG to BG (Hardedge)" gradient
GEGL:
 - Port the projection code, the code that composes a single image from a stack of layers, to GEGL
 - Port layer modes to GEGL
 - Port the floating selection code to GEGL

 - Prepare better and more intuitive handling of the floating selection
 - Add File->Debug->Show Image Graph that show the GEGL graph of an image
