1897Brit. Jrnl. Photogr. 8 Jan. 18/1 We understand that kromskops and sets of kromograms will shortly be obtainable from the Photo-chromoscope Syndicate Limited. 1898[see kromskop]. 1969H. & A. Gernsheim Hist. Photogr. (ed. 2) xliii. 523 In his Photochromoscope camera (1893) three separation negatives were taken in succession on one plate by means of a repeating back containing red, green and blue-violet filters. From these, diapositives were made by contact printing. When cut into the three separations and laid on the Kromskop viewing instrument (1892) containing filters of the same colour and mirrors, the optically superimposed Kromograms appear in perfect colour. |
