Photo-montage 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 final image is then photographed so that it appears as a seamless photographic print. Photo montage today is often done digitally, using editing software such as adobe Photoshop, instead of physically cutting up and arranging images together. 

The first example of photo-montage was an image by Oscar Gustave Rejlander in 1857, called “The Two Ways of Life” This technique was quickly adopted by many other artists, including Henry Preach Robinson in 1858 with “Fading Away”

Photo-montage was first used to express political messages, for example in 1915 it was used by the Dadaists for their protests against the First World War. Dadaists were artists named for their participation in the Dada Art Movement, revealing the reaction to horrors of war. It was later adopted by the surrealists, using the possibilities of photo-montage to combine a wide range of images to reflect the ideas of the unconscious mind.
