A Color Timing Calculating Machine

G. T. Keene, A. J. Sant, J. D. Clifford

A machine calculator based on the Wheatstone bridge principle is described. This machine will present information for additive or subtractive printing directly from the input data, which may be negative densities of a gray card in the scene or integrated full-frame negative densities. The input or output data appear simultaneously on the machine, thereby reducing the possibility of error. The timing error is ±0.03 log E for the first print relative to the standard print for the system in use.
