Adobe Photoshop CS5 was released few months ago and if you haven’t purchase it. You’ve got to check out their new amazing feature
Content-Aware Fill
One of the most exciting new features in Photoshop CS5 is the remarkable ability to remove an image element and magically replace it with details that match the lighting, tone, and noise of the surrounding area so that it looks like the content never existed. Now, you can make substantial changes to photo composition quickly and easily, as even large complex subjects can be seamlessly erased.
You can use Content-Aware Fill with the Spot Healing Brush or as an option of the Fill feature to replace content in an active selection. Selecting the Content-Aware setting with the Spot Healing brush changes the way the tool fills in the areas you paint. This retouching approach is designed to account more fully for the structure and detail of the image elements that surround the painted area, providing a near-invisible result when removing unwanted objects. Alternatively, you can select the object to be removed, and then replace the area with synthesized details from the area surrounding the selection, simply by using the Content-Aware option in the Fill dialog box.
