摘要： Disclosed is a color photographic element comprising a multilayered blue light sensitive record, a multilayered green light sensitive record, and a multilayered red light sensitive record, the red record comprising two or more layers of differing light sensitivity, the most light sensitive layer of the red record containing a red light sensitized first emulsion having at least one wavelength of peak absorption, and at least one of the two most light sensitive layers of the red record containing a red sensitized second emulsion, wherein the first emulsion exhibits, as measured at 0.2 density units above Dmin, at least one wavelength of peak absorption that is longer than the shortest wavelength of peak absorption of the second emulsion. The element provides an advantageous combination of speed and color rendition.

摘要： This invention is a system and associated method for monitoring and controlling independently the supersaturation and halide ion concentration, during the precipitation of a silver halide emulsion in a precipitation vessel. The introduction of a silver salt is controlled in accordance with a predetermined program, which in turn is responding to the supersaturation signal measured in the vessel by a supersaturation sensor. The sensor is comprised of a true silver ion electrode and a silver-silver halide electrode. The introduction of the halide salt is controlled in accordance with the predetermined program, which in turn is responding to the halide ion concentration signal measured in the vessel by a silver-silver halide electrode and a reference electrode.
