ISO 21550:2004 specifies methods for measuring and reporting the dynamic range of electronic scanners for continuous tone photographic media. It applies to scanners for reflective and to scanners for transmissive media.
Abstract
Overview
ISO 21550:2004 - Photography - Electronic scanners for photographic images - Dynamic range measurements specifies standardized methods to measure and report the of electronic scanners used with continuous-tone photographic media. The standard applies to both (prints) and (film/transparency) scanners. Measurements are performed in the digital domain by scanning a prescribed test chart and analyzing the resulting data to determine the scanner Opto‑Electronic Conversion Function (Scanner OECF), incremental gain, noise and the ISO scanner dynamic range.
