    • A method is disclosed for electronically processing an image scanned from a scene exposed onto a color negative photographic element. The element is especially capable of producing images that, when scanned, converted to electronic form, corrected and then converted to a viewable form, exhibit excellent color, reduced granularity and improved sharpness. The photographic elements contain blue, green and red recording layer units capable of forming spectrally differentiated dye images. The layer units are substantially free of colored masking coupler, and each exhibit a dye image gamma of less than 1.5. The element exhibits an exposure latitude of at least 2.7 log E. The gamma ratios of the blue, green and red recording layer units are between 0.80 and 1.2. A method for producing a viewable image is additionally disclosed.

    • A color negative film is disclosed capable of producing dye images suitable for digital scanning. With a green recording layer unit coated over a red recording layer unit a red exposure information containing dye image record is created that better matches human visual color perception when reversed to a positive that is red with unsought densities in the same spectral region as the red exposure information containing dye image attributable to blue and green recording layer units subtracted, by (a) withholding colored masking couplers from the recording layer units, (b) employing tabular grain emulsions with average aspect ratios of less than 15 in the green recording layer unit, and (c) placing spectral sensitizing dye in the red recording layer unit that exhibits an overall half-peak absorption bandwidth of at least 50 nm bridging the green and red regions of the spectrum, with absorption at 560 nm being in the range of from 80 to 95 percent of maximum absorption, which is located in the spectral region of from 575 to 710 nm.
    • 公开了能够产生适于数字扫描的染料图像的彩色底片。 通过涂覆在红色记录层单元上的绿色记录层单元,产生包含染料图像记录的红色曝光信息,其在与红色曝光相同的光谱区域中与未测量的浓度相反时,将人类视觉色彩感觉更好地匹配 通过(a)从记录层单元中扣留着色掩蔽成色剂,(b)在绿色记录层单元中使用平均长径比小于15的片状颗粒乳剂,减去归因于蓝色和绿色记录层单元的染色影像的信息, 和(c)在红色记录层单元中放置光谱增感染料,其表现出桥接绿色和红色区域的至少50nm的总体半峰吸收带宽,其中560nm处的吸收在80 至95%的最大吸收,其位于575至710nm的光谱区域。

    • A color negative film is disclosed capable of producing dye images suitable for digital scanning comprised of a support and, coated on the support, a series of hydrophilic colloid layers including at least two red recording emulsion layer units capable of forming a dye image of a first hue, at least two green recording emulsion layer units capable of forming a dye image of a second hue, and at least one blue recording emulsion layer unit capable of forming a dye image of a third hue, wherein, (1) the series of hydrophilic colloid layers include the following sequence, starting with the layer unit coated nearest the support: (a) a slower speed red recording layer unit, (b) a slower speed green recording layer unit, (c) a faster speed red recording layer unit, and (d) a faster speed green recording layer unit; (2) colored masking couplers are absent from the recording layer units; (3) tabular grain emulsions sensitized to the green and red are employed in the green and red recording layer units, respectively, and (4) spectral sensitizing dye in the red recording layer units exhibits an overall half-peak absorption bandwidth of at least 50 nm bridging the green and red regions of the spectrum, with absorption at 560 nm being in the range of from 80 to 95 percent of maximum absorption, which is located in the spectral region of from 570 to 710 nm.
