This section of the Great Wall of China is at Mutianyu, a dramatic hilly setting 56 miles north of Beijing. It is a more relaxed section of the wall, with far fewer tourists and less intrusive vendors and self-appointed "guides" than I found at Simatai on my previous visit to the wall in 2004. (The most commercialized section of the wall is at Badaling, only 44 miles from Beijing.) I wanted to convey the relaxed, relatively un-crowded nature of the Great Wall at this place by including only about five people in this picture. It was a foggy, overcast day, and I wanted to express the mood of the weather as well. To do this, I extended my zoom lens to about 300mm and shoot into the mist. The long telephoto focal length flattens perspective, bringing the towers closer together. It also defines the fog by showing us the foreground clearly, yet greatly softening detail in the background.
