Photoshop is very popular software, majorly used for photo editing and manipulation. Clipping Path to use them in a different way or place for a better effect is one of the most common activities performed in the very handy software.
One of the more cutting-edge features delivered in Photoshop CS6 Beta is the brand new Content-Aware Move Tool. The concept of this tool is that you will be able to select objects in your image and move them around and Photoshop will do all the edge work and re-blend your object (face, person, building, car, etc... etc...) into whatever part of the image you move it to.
The tool is a far cry from being perfect and often time's takes a little tweaking and playing with to get a great result.
