Photographers have been manipulating and compositing images since shortly after the medium's invention in the 1820s. Two notable artists who utilized early photomontage were Henry Peach Robinson and Oscar Rejlander. In this process, several different negatives are exposed to the same photographic paper, which is then developed. The result is a print (often depicting a spectacular or impossible scene) that appears to have been created from one negative. Digital compositing has been possible since the early 1990s with the invention of Adobe Photoshop.
