Abstract: Infrared radiation has been utilized in many fields of investigation. The research presented here was performed to investigate the application of infrared densitometry as a feasible and valid method of development determination. An apparatus was modified to emit and detect infrared radiation. Partially processed films were metered by the application of infrared densitometry and an empirical formula was derived to calculate the corresponding fixed-out white-light densities. The D-log E curves were plotted from the calculated data and comparison studies were made with curves drawn in the conventional manner. When the calculated data were derived from an empirical power series formula, the resulting sensitometric data were agreeable within acceptable limits.
