Abstract

A method is proposed to measure scattering characteristics of non-processed photographic emulsions without using expensive or complicated computer processing techniques. A photo goniometer was assembled from a standard spectrometer, a lightsource and a photodiode. Film samples were measured both in air and in an index matching liquid comparing samples of two main categories, continuous tone pictorial emulsions and graphic arts copyfilms. It was learned that the measurements separated the samples into the above mentioned categories based on response variables such as scattergram and its corresponding Fourier Transform. This method is proposed as a tool in emulsion design engineering or quality control as a first order quick check or sorting on scattering characteristics and is not intended as a complete high precision tool to analyze and characterize emulsions for their scattering characteristics and properties.
