Photographic Harmonies is a wide-ranging collection of photographic work spanning more than 50 years and over 50 national parks, monuments, preserves, and conservation and wilderness areas. Included are works in color, black and white, monochrome and infrared. Each photo was selected because it helps to convey what the authors call Òthe harmonies of the landscape,Ó and the images are organized according to the musical styles that reflect the spirit of each place.
