what is photomontage in photoshop?

Photomontage is the process and the result of making a composite photograph by cutting, gluing, rearranging and overlapping two or more photographs into a new image.Sometimes the resulting composite image is photographed so that the final image may appear as a seamless physical print. A similar method, although one that does not use film, is realized today through image-editing software. This latter technique is referred to by professionals as "compositing", and in casual usage is often called "photoshopping" (from the name of the popular software system). A composite of related photographs to extend a view of a single scene or subject would not be labeled as a montage, but instead a stitched image or a digital image mosaic.
