A method of holographing an object wherein, in order to obtain a required diffusely illuminated back-ground, the object is holographed against a background constituted by a hologram which is adapted to simulate a real background from which the hologram has been produced. Typically, the object is holographed against a hologram of a matt white box. The background hologram is preferably a hologram used in its pseudoscopic mode but may be a hologram used in its orthoscopic mode but projected as a real image. |
