Abstract
An apparatus and procedure are described by which CFF-logI functions were obtained for a range of LDR values with two sizes of foveal area. When the data are plotted against log light pulse brightness, i.e., uncompensated, the relative positions on the y axis of the sets of points corresponding to the different LDR’s vary with brightness level. When the results are shown as a function of log brightness which has been compensated according to the Talbot-Plateau law, the higher the LDR, the lower the set of points on the y axis, irrespective of brightness level. The effect of an increase in area is to raise the position of a given set of points.
