摘要： Disclosed is a silver halide color photographic light-sensitive material including at least one red-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer, and at least one blue-sensitive silver halide emulsion layer on a support, and having an ISO sensitivity of 640 or more, wherein the material exhibits a color saturation evaluation value &eegr;, represented by equation (I) below, of −15 dB or more. &eegr;=10 log(1/VT) [VT=(⅙)×((62−Y1)2+(62−Y2)2+(62−Y3)2+(62−Y4)2+(62−Y5)2+(62−Y6)2)] (I) In Formula (I), each of Y1 to Y6 is a value obtained by exposing 12 colors of a Macbeth color chart with six exposure amounts, from −1 under to +4 over, measuring the saturation of each resultant color, and averaging the data (chroma values) for a corresponding exposure amount.

摘要： A high-speed color negative photographic material which comprises, a support having provided thereon, at least one red-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one blue-sensitive emulsion layer, and is designated so as to acquire a specific photographic sensitivity (defined in detailed description of the invention) of 800 or above, and has a combined total of silver coverages ranging from 3.0 g/m.sup.2 to 9.0 g/m.sup.2 so as to minimize an increase in fog, a decrease in photographic speed and deterioration in granularity, which heretofore have occurred in high-speed photographic materials during long-range storage before used. In addition, the present photographic material enables enhancement of pressure resistance and processing efficiency.

摘要： A printer control pictorial tool consists of an eye portion having a neutral gray, portraits arranged around the eye portion, and a gray background. The eye portion and the portraits are located within a photometric range that is equal to or less than a range covered by a photometry device of a photo-printer. The gray background has the same average gray density as the eye portion has. An area having a complementary color to a flesh color of the portraits is provided within the photometric range. The size, color and density of the portraits and the complementary color area are determined such that photometric values obtained from the photometric range are approximately equal to those obtained from the eye portion.
摘要翻译：打印机控制画面工具由具有中性灰色，眼睛周围布置的肖像和灰色背景的眼部组成。眼睛部分和肖像位于光度范围内，该光度范围等于或小于由照相打印机的测光装置覆盖的范围。灰色背景具有与眼睛部分相同的平均灰度密度。在光度范围内提供具有与人像肉色互补的区域。确定肖像的大小，颜色和密度以及补色区域，使得从光度范围获得的光度值近似等于从眼部获得的光度值。
