Model examination of the influence of edge effects on the acutance of photographic image

In the paper, the results of simulation model examination of the influence of edge effects connected with both inhibiting and accelerating the photographic development process on the sharpness of images recorded on light-sensitive silver halide materials are presented. In the examination a three-stage model of the photographic recording of image information was used, which was been worked out by the Imaging Science Group of the Wroclaw University of Technology. The functioning of this model was compared to that of the well known Nelson's model.
