    • 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.
    • 公开了一种用于电子处理从暴露于彩色负面照相元件上的场景扫描的图像的方法。 该元件特别能够产生图像,当被扫描时,被转换成电子形式,被校正,然后转换成可视形式,表现出优异的颜色,降低的粒度和改善的清晰度。 摄影元件含有蓝色,绿色和红色记录层单元,能够形成光谱分化的染料图像。 层单元基本上没有着色掩蔽成色剂,并且各自表现出小于1.5的染料图像γ。 该元件的曝光宽容度至少为2.7logE。蓝色,绿色和红色记录层单元的伽马比值在0.80和1.2之间。 另外公开了一种用于产生可视图像的方法。
