Added to this, and stemming partly from it, is the fact that a black-and-white image can be treated to much greater extremes (such as in contrast and key) than a typical color image. As just one example of this, consider the usual processing limits for a color image, with highlight and shadow clipping being major considerations. Not slipping beyond the limits is fast becoming a rule, even an obsession, in digital processing. But try exceeding the highlight and shadow limits in black and white, as film photographers have done for decades (see the image by Bill Brandt in this chapter), and it will not necessarily look wrong. The latitude for creative expression, in other words, is built into black and white.
