Making one image from several images is called photomanipulation, or a photoedit if you will.
Sometimes i like to get some of my photo’s and make something special. It can be something real, or something less real. In this case it is impossible as a photograph but with a nice end result. In this case I used three seperate photo’s. One of the ball in the snow, one of a bird standing on ice and one of little bird feet stamps on the snowy ice.
This type of editing is also possible in more real end results. For instance, adding an absent relative to your wedding photo’s or one of your children if you just cannot get them together at the same time.
