- Abstract
- The dependence of the optical density of developed photographic materials upon the method of its measurement was first demonstrated by Callier.<sup>1</sup> He discussed the effect of light scattering by the photographic image and presented data which seemed to justify the empirical relation: <tex>$D||\, = QD\parallel\!\!\!\!\!-$</tex> where <tex>$D||$</tex> (specular density) is the value obtained with the developed image in a specular beam, <tex>$D\parallel\!\!\!\!\!-$</tex> (diffuse density) the value obtained with diffuse illumination, and Q a constant factor greater than unity.
