Describes the spectral characteristics of an ISO standard camera lens and a method for determining the contribution of spectrally selective lenses to the colour of the final film image. The procedure can also be applied to other optical elements in the camera.
Abstract
Overview
ISO 6728:1983 - Photography - Camera lenses - Determination of ISO colour contribution index (ISO/CCI) specifies a standardized method to quantify how a camera lens (or other optical elements) shifts the overall colour of a photographic film image. The standard defines an spectral reference, prescribes measurement requirements (monochromator bandwidth, integrating sphere), and provides a calculation procedure to produce a three-number - typically reported as “ISOKCI 0/5/4” for the reference lens.
