Course outline in basic chapters

1/ Physical and Trichromatic Color Reproduction – the micro-dispersion method, the Lippmann method, the Maxwell method, the mosaic methods, the lenticular methods, the subtractive principle, relief-images.

2/ The Color Triangle – color terminology, trichromatic matching, Grassmann´s laws, tristimulus color space, negative tristimulus values, color matching functions, NPL trichromator, transformation of primaries, CIE 1931 chromaticity diagram, properties of the XYZ system, uniform chromaticity diagram, uniform color scales, spectrophotometry, colorimeters.

3/ Visual Appreciation – the basis of judgement, variations in hue, lightness and saturation, priorities, factors affecting apparent color balance, the physiology of human color vision, spectral sensitivity curves of the retina, defects of trichromatic color reproduction, errors in additive methods, defects of subtractive principle, the Ives-Abney-Yule compromise.

4/ Adaptation and Exact Color Reproduction – change in appearance of colors as the adapting conditions change, dark and bright surroundings, influence on the contrast of the image, constancy of perception, conditions of exact color reproduction, memory colors, preferred color reproduction, comparative and single stimulus methods.

5/ Subtractive Methods in Color Photography – primary and secondary color development, integral tripacks, processing with the couplers incorporated in the film, reversal processing, processing with the couplers in developers, the philosophy of color negatives.

6/ Masking and Colored Couplers – conrast masking, colored couplers, inter-image effects, inter-image effects, masking when making separations, masking for exact color reproduction, masking for approximate color reproduction, calculation of mask contrasts.

7/ Chemistry of Color Photography – color development, developing agents, couplers, colored couplers, the dye-coupling reaction, the physical form of the dye, color developing solutions, silver bleaching, processing sequences.

8/ Printing – printing motion picture negatives, integrating to gray, printing amateurs´negatives, the variables to be corrected, early printers, color analyzers, additive and subtractive printers, digital scanning, laser recording.

9/ Recent Photographic Materials – design and structure of negative, reversal and positive photographic materials, materials with transparent and non-transparent base, intermediate materials, digital intermediate, instant photographic materials, zero-order diffraction process for color reproduction.

Learning outcomes

The development of color photography, color television and color printing demands a very wide and deep understanding of the facts of color mixture and color perception.

Evaluation methods and criteria


This course has not lost sight of the practical side; lectures are complemented by experiments, tests and practical demonstrations. The subjects are treated more from the standpoint of technique rather than science in the hope of rendering the program more useful for practical applications.
