Intro to Compositing
Creativity in the Photoshop Darkroom by Harold Davishttp://photo.net/learn/digital-photography-workflow/advanced-photoshop-tutorials/intro-to-compositing
Intro Image: To create this photo composite, I shot a macro of a marble and its shadow, and then used Photoshop to add the view of the ocean in place of the natural shadow.
Compositing, or photo compositing, is the technique?art and craft?of combining images to create a new image. The newly created image often presents its own version of reality.
Compositing is often used in advertising, where the use of the technique is sometimes intended to be obvious and at other times is designed to be seamless. Compositing has sometimes been used in journalism, although this use is generally frowned upon when discovered. The opprobrium hasn?t stopped the usage?for example, the Communist party under Stalin used old-fashioned compositing to ?purge? out early party leaders as they were discredited by altering historic photographs to remove those who had been purged from the party.
