Abstract

The digitization of photographs by estimating and recording the dye concentrations of each pixel can be used for the device-independent and highly accurate storage and reproduction of photographs. Previous work on this subject has concerned itself with the color accuracy without regard to spatial considerations. This paper represents a beginning in the study of effects and limitations of the spatial resolution of this process, and more importantly of the subtle relationship between spectral accuracy and spatial resolution. Two such relationships are introduced here: the first is spectral inaccuracy due to the spatial integration over the detection spot; and the second is the effect of multiple light bounces within the gelatin of the photographic paper.
