It was later adopted by the surrealists who showed the possibilities of photo montages and the workings of the unconscious mind. In 1923 Aleksander Rodchenko , a Russian constructivist, started experimenting with photomontage as a way of creating striking socially engaged imagery concerned with the placement and movement of objects in space. Another person who experimented with photo montages was the German artist, John Heartfield. He reconstructed images from the media to protest against Germany’s regime. Aswell as Peter Kennard whose photomontages explored issues such as economic inequality, police brutality and the nuclear arms race between the 1970s and the 1990s.
