Paper Abstract

The densitometric approach to integral shifts in color photographic images upon dark storage in various conditions and the colorimetric approach to color hue shifts in the same images were shown to be non-coinciding in Arrhenius-based predictions of image permanence. This is shown to be no argument for or against any of the two approaches, but merely results from principally different information content involved in data obtained in each approach. The predictions are always more short-termed for images becoming unsatisfactory by color mismatching than those for their integral decay. Both modes of predictions, as compared with direct experiment whenever possible, seem to give reasonable data.
