Forty of Ansel Adams's black and white photographs are accompanied by his commentary upon taking them.

In 1941, Ansel Adams photographed America's national parks for a series of murals that would celebrate the country's natural heritage. Because of the escalation of World War II, the project was suspended after less than a year, but not before Adams had produced these images, which illustrate both his early innovations and the shape of his later, legendary career as America's foremost landscape photographer.
