Abstract: A photographic apparatus and method for adding artificial backgrounds. The apparatus is intended to be utilized in combination with a conventional view camera and comprises a control structure including two masking plates pivotably mounted between the film plate and the lens of the camera, which are operable to be placed in either a first operative position against the film plate or a second inoperative position along the sidewall of the camera. A background transparency is attached along with a product mask to one of the plates and a background mask is attached to the other plate. The product and background masks are created from a photograph taken of the product using positive-type film. Once attached to the plates, the two masks are aligned or "registered" with the image of the product projected through the lens of the camera, utilizing the precise alignment means provided for controlling the orientation of the masking plates.
