This paper describes the effect of thickness of light scattering layer which is sandwiched between a pair of AgX films, original negative (or positive) film and this reversal positive (or negative) film. In this method, it was shown that the light scattering power of light scattering layer has much importance to enhanced and density extracted picture. The optical density of enhanced picture increases as the thickness of light scattering layer decreases, on the other hand, the line width of enhanced picture increases, as the thickness increases. From the experimental results, it is ascertained that the thickness of light scattering layer and the exposure light intensity have the optimum condition, respectively.
