Adobe Photoshop is one of the most advance tools in digital image editing and for developments as well such as icons and some other stuff.  Photoshop now is on CS5 which handles several new features and one is Content-Aware Fill where you can magically fill in spaces on digital images matching the tones, lightning and noise of the images making it as if it existed on the image.  You can find more of the new features on their site.
