ABSTRACT:
A method of composing pictures of objects comprises the steps of exposing a frame of a record medium such as a frame of a roll of film or a target in a television camera via a camera lens while masking a portion of the field from exposure by a first mask disposed in front of the lens. The field or frame of the record medium is then re-exposed while masking a previously unmasked portion of the field or frame. The foregoing is accomplished by apparatus in one instance comprising a camera having means for transporting film, a lens, first and second masks serving to block light to complementary portions of the film, a light shade supported by the lens to sequentially support the masks in front of the lens at a distance sufficient to inhibit exposure of complementary portions of the film.
