Abstract: A method of photographic printing including making a stepped exposure of a simulation of a properly exposed gray card for a film to be printed having particular D/log E characteristics, and the film-mask-colored element for film having a colored mask, for a number of different periods of time on at least one sheet of photographic paper having certain D/log E characteristics; processing each sheet of paper; comparing each such exposure step of a simulation of a properly exposed gray card to a gray reference to determine the proper exposure time from the step most closely approaching the gray reference; and measuring the intensity of the exposing light to obtain the proper intensity which, with the proper time, determines the exposure to be used to print all film having D/log E characteristics generally similar to the particular D/log E characteristics on paper having D/log E characteristics generally similar to the certain D/log E characteristics.

Abstract: A method of photographic printing comprising making at least one exposure of a simulation of a properly exposed neutral gray card for a film to be printed, having particular D/log E characteristics, and a film-mask-colored element for film having a colored mask, for at least one predetermined period of time on at least one sheet of photographic paper having certain D/log E characteristics; processing each sheet of paper; and comparing each such exposure of a simulation of a properly exposed gray card using color filters to determine the proper exposure time and color filtration to be used to print all films having D/log E characteristics generally similar to the particular D/log E characteristics on paper having D/log E characteristics generally similar to the certain D/log E characteristics.

Abstract: A method of photographic printing comprising making at least one exposure .Iadd.through a color filter calculator device .Iaddend.of a simulation of a properly exposed neutral gray card for a film to be printed, having particular D/log E characteristics, and a film-mark-colored element for film having a colored mask, for at least one predetermined period of time on at least one sheet of photographic paper having certain D/log E characteristics; processing each sheet of paper; and comparing each such exposure of a simulation of a properly exposed gray card using color filters to determine the proper exposure time and color filtration to be used to print all films having D/log E characteristics generally similar to the particular D/log E characteristics on paper having D/log E characteristics generally similar to the certain D/log E characteristics.
