Abstract

4187. Lippe, P. G. von der. Feb. 18, 1913, [Convention date]. Enlarging, copying and reducing. - In apparatus for the photographic production of shadowless pictures and gelatine reliefs, in which the object to be copied is illuminated from the front, the objective b of the camera is surrounded by a parabolic reflector a, in the cavity of which is arranged a circular source of light formed of a ring of electric lamps c, or of a circular electric glow, gas, or vapour lamp, so that the object during exposure is illuminated exclusively by rays parallel to the axis of the objective.
