A densitometric technique is described which yields analytical dye densities from a negative- positive color print film in a time less than would normally be required to process the film. In this technique, a correlation is established between the dye density produced by the complete process and the silver density produced by the initial development, the latter being determined by an application of infrared densitometry. Equipment utilized and procedure followed are described and some theoretical aspects and limitations reviewed.
