Cancels and replaces the first edition (1983). Specifies the geometric conditions for measuring the reflection density of photographic and graphic art materials. Specifies illumination at all azimuth angles. Does not cover those situations where light has been deliberately polarized. Also applicable to the measurement of these characteristics for other materials.
