This International Standard describes a method for determining the intrinsic root mean square granularity (rms-granularity) of photographic films. Intrinsic rms-granularity refers to those density fluctuations produced solely by the distribution of developed image forming centres in the photographic emulsion.<\/p>\n

Continuous-tone monochrome (silver absorbing species) and colour (dye absorbing species) materials coated on a transmitting support can be measured by the procedures described in this International Standard. This International Standard is intended for imaging systems with viewing magnifications between 5\u00d7 and 12\u00d7 (see Annex A).<\/p>\n

The following kinds of granularity measurements are not covered by this International Standard, even though they are photographically important:<\/p>\n
