Abstract

Abstract A camera has a lens that has a field of view and a film pack for positioning film for exposure substantially along a focal plane of the lens. A screen is positioned to block a portion of the field of view of the lens. The camera also has a flash unit for illuminating the screen during film exposure whereby light from the field of view may be directed by the lens to one portion of film positioned along the focal plane and light from the screen directed to a second portion of the film.

Claim 9
Dependent Claim 114 words
In a camera of the type having means for positioning film for exposure to light from a field of view of a lens along a focal plane of the lens, the improvement comprising a screen mounted adjacent said lens in position to block a portion of the lens field of view and means for directly illuminating the portion of said screen mounted at said position blocking a portion of the lens field of view whereby light from the field of view may be focused by the lens onto a first portion of film positioned along the focal plane and light from the screen focused by the lens onto a second portion of the film.
Claim 10
Dependent Claim 114 words
In a camera of the type having means for positioning film for exposure to light from a field of view of a lens along a focal plane of the lens, the improvement comprising a screen mounted adjacent said lens in position to block a portion of the lens field of view and means for directly illuminating the portion of said screen mounted at said position blocking a portion of the lens field of view whereby light from the field of view may be focused by the lens onto a first portion of film positioned along the focal plane and light from the screen focused by the lens onto a second portion of the film.
Claim 11
Dependent Claim 33 words
The improvement in a camera of claim 8 further comprising means for positioning a transparency bearing a prerecorded image between the lens and focal plane in substantial register with the film second portion.
