Pictorial technique in which cut-out illustrations, or fragments of them, are arranged together and mounted on a support, producing a composite picture made from several different pictures. It differs from collage in using only ready-made images chosen for their subject or message. The technique is widely used in advertising. Photomontage uses photographs only. In motion pictures, montage is the sequential assembling of separate pieces of thematically related film by the director, film editor, and visual and sound technicians, who cut and fit each part with the others to produce visual juxtapositions and complex audio patterns.
