Abstract
A method for transforming each tone of gray in a black-and-white image into a different color, enabling viewers to extract more information. Using only two intermediate separations, red and blue, the process is even simpler and faster than the red/green/blue process reported in AD-717 143. It also gives a more evenly spaced range of hues. However, with the improveents described in the report, the three-separation technique has the greater flexibility. In the two-separation process: One separation is made from the original positive and developed; Another is contact-printed from the first--not emulsion-to-emulsion--and developed; The first is contact printed, emulsion-to-emulsion, on color film, using a red light source; With careful image registration, the second is contact-printed, emulsion-to-emulsion, on the same material under a blue light; The print is processed. Examples are included.
