Definitions

the chromogenic monochrome films on the market today sandwich three emulsions together that develop chromogenically to three colours in standard colour developer.
This film is identical to colour film, except that the three levels have three speeds instead of three colour sensitivities.
the photographer selects the high, medium or low speed emulsion by selecting a red, green or blue filter in the enlarger.
three pictures are made simultaneously on three films, letting the printer select the optimal one.
the selection is made only on the image as a whole.
panchromatic paper must be used, which precludes the use of variable contrast paper and a bright safelight in the darkroom.
the second is that the technique is not extendable to colour film.
the bottom row 540 mixes the high and low curves. In the region where both high and low emulsions are responding, a blending of both images gives a signal to noise ratio superior to either individually.
the best weighting ratio for each density is known from statistical mathematics to be, for the lower layer, the S/N of the low divided by the S/N of the sum of both. For the high layer, the S/N of the high is divided by the same sum.
the invention employs image capture of a developing film multiple times during the development process.
the scans use a colour that does not expose the film and that is not absorbed by the antihalation dye, couplers, or layer separation dyes, normally infrared.
the timings of the scans give a normal, an extra long and an extra short development.
