Abstract
Abstract A one-time-use camera preloaded with a color negative silver halide photographic element is disclosed. The element is capable of producing images after imagewise exposure that, when developed, converted to electronic form, digitally 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.
