A note about ISO FDIS documents

This document is a Final Draft International Standard (FDIS) published by ISO. An FDIS is a Draft International Standard that has previously been approved by ISO members, and is issued for a final Yes/No vote within a period of two months from publication. Note that if technical comments are received during this period, they are no longer considered at this stage, but registered for consideration during a future revision of the International Standard. In the rare event of an FDIS not being approved, the FDIS is referred back to the originating Technical Committee for reconsideration in the light of the technical reasons submitted in support of the negative votes received.

Abstract

ISO 10505:2009 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.

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 ISO 10505:2009. ISO 10505:2009 is intended for imaging systems with viewing magnifications between 5x and 12x (see Annex A).

The following kinds of granularity measurements are not covered by ISO 10505:2009, even though they are photographically important:

  • reflecting materials (photographic papers);
  • materials having emulsion coated on both sides of the support (e.g. some X-ray films);
  • the estimation of the noise power spectrum (Wiener spectrum).
