ISO 7589:2002

Photography — Illuminants for sensitometry — Specifications for daylight, incandescent tungsten and printer

Scope

This International Standard specifies the spectral characteristics of illuminants for sensitometry appropriate for
evaluating camera films used for pictorial photography in natural daylight, studio tungsten and photoflood, including
colour and black-and-white films, both reversal and negative types, and for evaluating black-and-white papers used
with incandescent tungsten printers. It also describes methods for evaluating the acceptability of illuminants for
sensitometry and specifies tolerances.
It does not include illuminants for use with colour papers, since this would need to take account of the coloured
mask of the negative material, for which no standard information is at present available.
