Draft Wide - Gamut

Color gamut refers to the range of colors that can be reproduced by an imaging system. The definition of gamut is quite clear for displays and for hard-copy printing. Color image science experts disagree, however, on the definition – or even applicability of the concept – of gamut for cameras. I argue that there is no such concept as “capture gamut.” At the conclusion of this note I’ll outline my reasoning – but first we have to take a tour through camera signal processing.

I assume you’re fairly familiar with the principles of color science, and with its application in video, topics discussed in chapters 21 and 22 of my book (“ DVAI ”).
