Although this is a great book for any art lover it is a must for the plein air (outdoor) painter. It demonstrates how Cezanne transformed his "motif", the scene he has selected, into a painting by showing photos of the motif side by side with his paintings. Machotka, an artist himself, discusses the artistic problems presented by each scene and Cezanne's various solutions as they vary over his development as an artist. Machotka is knowledgeable, thoughtful and writes well. This book will certainly extend your appreciation of Cezanne and if you paint plein air, will likely make you a much more observant and better painter. As a painter this is one of the few books on composition and technique that I recommend to other painters.
