Paper Abstract

This paper describes experiments which explore the ways in which variations in film and processing influence noise through their effects on the sensitometric curve shape and silver granularity. These include comparisons of several film types and processing conditions for which total radiographic noise from screen exposures and granularity from light exposures are analyzed relative to the instantaneous gradient at the measured density. It is seen that film granularity may indeed contribute substantially to total noise under conditions of low quantum mottle visualization.
