Photomontage

n. superimposition of photographs, combination of two or more photographs

Photomontage is the process (and result) of making a composite photograph by cutting and joining a number of other photographs. The composite picture was sometimes photographed so that the final image is converted back into a seamless photographic print. The same method is accomplished today using image-editing software. The technique is referred to by professionals as "compositing", and in casual usage is often called "photoshopping".
