ABSTRACT:
A Fresnel lens or mirror is disposed between a worktable upon which an object can be placed and a background-image generator for a photographic apparatus whose subject and illuminating flash lamp are synchronized with the camera together with a flash lamp forming the light which is directed by the Fresnel element through or across the object and the objective lens unit so that a mirror ahead of the latter can direct the light onto the backdrop.
