Neurobiologist Margaret Livingstone addresses these and many other questions in Vision and Art, a lively look at the science underlying art. She writes accessibly, but with plenty of technical depth, on such matters as the nature of light and the visible spectrum, the organization of visual-image processing, the structure of the vertebrate eye and brain, and individual and culturally conditioned perceptions of color. Using well-known works of art as case studies, she offers fascinating bits of trivia (on, for instance, how pastels are made and why purple dyes are so rare) alongside practical information for artists (for example, how high-contrast contours and evenly distributed luminance attract the eye).
The result is a literate, lucid blend of art and science that will appeal to artists and connoisseurs alike. --Gregory McNamee
