Abstract
A system and method of image reproduction in color with preferential tone mapping in which the image reproduction is subjected to a scene parameter transformation which when taken in conjunction with untransformed characteristics of the image reproduction system and method results in a reproduced tone mapping having instantaneous gamma values of viewed reproduction density relative to density of the original scene which are greater than 1.0 and less than 1.0 plus 0.35 times scene exposure density over a scene exposure density range of from 0.6 to 1.45 as measured relative to a zero density, 100% diffuse reflector in the original scene. Preferably, the instantaneous gamma values within this scene exposure density range further lie substantially within a range of values subtended by an angle of 14.degree. as measured from a reference point at 0.0 scene exposure density and 1.0 viewed reproduction density gradient.
