The various ways in which pictures can be made by both subtractive and additive displays are reviewed. Systems using these displays are all limited by errors caused by incorrect camera spectral sensitivities, and by the limited gamuts of reproducible colors. Subtractive systems are further limited by the unwanted absorptions of their colorants. Pictorial images are usually assessed by comparison with memories of familiar objects. Because such objects vary considerably in color appearance, the tolerances in images of pictorial scenes are quite large; however, these variations tend to be smallest for hue and largest for colorfulness, so that hue is the most, and colorfulness the least, important attribute in imaging. Six possible different objectives are described: spectral, colorimetric, exact, equivalent, corresponding, and preferred. Possible reasons for preferring increased contrast in images are discussed.
