ISO/TS 19264-1:2017 applies to scanners and digital cameras used for digitization of cultural heritage material.

NOTE This document addresses imaging of reflective originals, a future part two will address imaging of transparent originals.

Original materials include but are not limited to books, textual documents, drawings, prints, photographs, and paintings. Certain types of two-dimensional materials with complex surface geometry and or highly reflective surface elements require special illumination techniques that can fall outside the scope of this document.

NOTE ISO/TS 19264-2 will address transmissive materials.

ISO 5-4:2009 also specifies the requirements for polarization (if that feature is included) and for backing material, and makes recommendations regarding accuracy and linearity.

Although intended primarily for use in the measurement of the reflection characteristics of photographic and graphic arts materials, ISO 5-4:2009 is also applicable to the measurement of these characteristics for other materials.

ISO 5 standard diffuse density is primarily applicable to measurements of photographic images to be viewed on a transparency illuminator, or viewing box, to be contact printed, or to be projected with a system employing diffuse illumination.

ISO 5 standard projection density is primarily applicable to measurements of photographic images to be projected with systems employing optical condensers.

Although primarily intended for the measurement of photographic images, the densitometric methods specified in ISO 5-2:2009 are often applied to optical filters and other transparent materials.

ISO 5-1:2009 primarily provides a system for describing methods of measuring or specifying the transmission and reflection properties of photographic and graphic arts materials. The geometric and spectral conditions associated with such measurement are specified in ISO 5-2, ISO 5-3 and ISO 5-4.

ISO 3664:2009 applies in particular to:

• critical comparison between transparencies, reflection photographic or photomechanical prints and/or other objects or images;
• appraisal of the tone reproduction and colourfulness of prints and transparencies at illumination levels similar to those for practical use, including routine inspection;
• critical appraisal of transparencies that are viewed by projection, for comparison with prints, objects or other reproductions; and
• appraisal of images on colour monitors that are not viewed in comparison to any form of hardcopy.

ISO 3664:2009 is not applicable to unprinted papers.
