This experiment was an analysis of the difference in objective measures of image quality between chemical and physical development methods, including prefixation and postfixation processes. Of particular interest was the process outlined by Matejec1 for postfixation physical development. An investigation of resolving power and MTF for two fine grain films was carried out for four different development processes all possessing approximately the same speed capability. Both the effect of combined chemical and optical spread functions and the chemical spread alone were investigated through edge analysis using Fourier methods. A significant increase in image quality was found with the finest grain film (Eastman 5302) for prefixation while a significant decrease was found with the highly active Matejec's physical developer on the same film. A dye inhibition reaction on the dye sensitized emulsion, Panatomic-x, prevented analysis of image quality for postfixation processes for that film.
