Abstract

4609. Sontag, H. Oct. 27, 1911, [Convention date]. Studios and studio accessories.-An object a is photographed simultaneously with a background which is projected from behind on to a translucent screen b by a powerful lantern d. The screen b is coloured with a colour which has a weak chemical action, such as yellow, red, green or the like. The rays for lighting the subject falling on the front of the screen are thus absorbed or rendered inactive, while the rays from the luminous image on the screen produce an image of the projected background on the plate. The object may be photographed in daylight, or may be illuminated by artificial light g.
