Robert Adams is considered by many as one of the most important photographers of the 20th century. I think most people know him from his early work documenting the encroachment of people and development on the East slope of the Rocky Mountains near Denver. He was one of the first of the "new topographers" who considered the effect and presence of man in the environment as a logical progression in landscape photography.
One thing about Adams is he has continuously evolved and continued to explore the boundry between man and the environment in a variety of projects for the last 40 years. He is the kind of photographer that when I was younger I did not really care that much for, but in the last few years I have really come to appreciate his varied work and talent. He also wrote two of the best books on photography I have read. Why People Photograph and Beauty in Photography: Essays in Defense of Traditional Values.
This image, simply titled Longmont, Colorado, (1978) is from a project called Summer Nights. I love the omminous approaching storm clouds that seem ready to envelope the rather unsuspecting little carnival at the base of the mountains.
