Photographic Harmonies is a large format book with a wide-ranging collection of 193 landscape photographs spanning more than 50 years. Locations include over 50 national parks, monuments, preserves, conservation and wilderness areas in eight nations. Included are works in color, black and white, monochrome and infrared. Each photograph was selected because it helps to convey what the authors call "the harmonies of the landscape," and the images are organized according to the musical styles that reflect the spirit of each place.
