Granularity: Its Measurement and Relationship to Graininess
Root-mean-square granularity numbers have become an increasingly accepted parameter for ranking the relative graininess of photographic films. The significance of the number and the method of measurement are reviewed. The relationship of granularity to the graininess of the photographic image is dependent on the contrast, density level and measuring-instrument characteristics. The influence of print films on negative graininess is dependent on the contrast and sharpness of the print stock and the characteristics of the printer.
