In the late 1980s, Griffel became the director of the famed Cape Cod School of Art, the foremost center for the study of American impressionism, continuing the legacy of its founder, impressionist Charles Hawthorne, whose philosophy and theories about color and light influenced a century of great American impressionists. Here, she emphasizes how the delicacy and subtlety of light within a subject can be captured in a painting. The original hardback edition has become something of a classic since its 1994 publication. This first-ever paperback version is highly recommended for all libraries. For a detailed look at the techniques of perhaps the greatest impressionist, see James Heard's Paint Like Monet.
