Tho prlnclplo of It is based upon tho decomposition of white light by tho prism Tho colored object chosen as n model Is placed before be-fore a glaHS pinto bearing longitudinal Btilao or (lutings to tho number of five to tho millimeter. Thcso Millings act like very small prisms which do compose tho luminous b1iuuus proceeding pro-ceeding from tho Image at their passage pas-sage Into tho camera obscura. After tho proof la obtained, developed and dried It Is placed In Its position behind be-hind tho fluted plate. If then It bo Illuminated Il-luminated with the white light It Is seen through this plato to appear with the colors of tho object photographed. Tho dlsperslvo system of tho fluted plato has decomposed tho light into Its elomentary rays, and tho colored radiations havo been distributed upon tho sensltivo plate. |
