Specifies a method for calculating a spectral distribution index to evaluate the ability of expendable flash and electronic flash units to produce photographic colour results comparable with those obtained with daylight-type films exposed to daylight illumination.
Abstract
Overview
ISO 3028:1984 – Photography - Camera Flash Illuminants - Determination of ISO Spectral Distribution Index (ISO/SDI) defines a standardized method for evaluating the color quality of flash illuminants used in photography. The standard focuses on assessing whether expendable flash bulbs and electronic flash units deliver color reproduction comparable to results obtained with daylight-type films exposed to natural daylight. By providing a clear procedure for calculating the ISO Spectral Distribution Index (ISO/SDI), ISO 3028:1984 helps manufacturers, laboratories, and photographers ensure consistent color fidelity in photographic results.
