       measuring the intensity of the exposing light at the printing plane; exposing an additional sheet of paper, having D/log E characteristics generally similar to said D/log E characteristics, to an image on a film, having D/log E characteristics generally similar to said particular D/log E characteristics, with light at said measured intensity through the color filtration required to faithfully reproduce simulation of the image of a properly exposed gray card for said proper exposure time and processing said additional sheet of paper to obtain a print of the image on the film.   
     
     
        .Iadd.43.  A method of photographic printing comprising: making at least one exposure through a color filter calculator device 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;   comparing each area of each such exposure of said simulation of a properly exposed gray card to a gray reference to determine the proper exposure time and the color filtration to be used to print all films having D/log E characteristics generally similar to said certain D/log E characteristics to be used to print images from all frames of all films having D/log E characteristics generally similar to said particular D/log E characteristics on paper having D/log E characteristics generally similar to said certain D/log E characteristics;   adding any necessary color filtration in the exposing light;   measuring the intensity of the exposing light at the printing plane;   exposing an additional sheet of paper, having D/log E characteristics generally similar to said D/log E characteristics, to an image on a film, having D/log E characteristics generally similar to said particular D/log E characteristics, with light at said measured intensity through the color filtration required to faithfully reproduce simulation of the image on a gray card for said proper exposure time and processing said additional sheet of paper to obtain a print of the image on the film. .Iaddend..Iadd. 44.
