COLOR SCIENCE IN PHOTOGRAPHY

A parallel relationship is drawn between trichromatic vision and photo graphic colour reproduction. The mechanisms of common photographic sys tems are described in terms of the analysis of the spectral input and the synthesis of the output colour reproduction . The colour science o f photographic images is reviewed. The objective evaluation of colour reproduction by colorimetry and sensitometry is discussed in relation to the colour gamut. The subjective evaluation of colour reproduction is introduced by an account of the examination of acceptability of col our prints as a function of colour balance. The relation between objec tive colorimetric colour differences and subjective assessment is show n using a suitable model of colour appearance in the generation of a c olour reproduction index.
