If I take a picture given to us by nature, which appears singular, but which is in reality triple in terms of color, and disassemble it onto three distinct pictures, one red, one yellow and one blue; and if I obtain a separate photographic image of each of these three pictures which reproduces its particular color; it will be sufficient to join the three resulting images into a single image in order to possess the exact representation of nature, color, and modeling all together. - Louis Ducos Du Hauron , 1000 Photo Icons by Anthony Bannon (Foreword), George Eastman House , ISBN: 3822820970 , Page: 302
