'Cigarette Ash Landscape' is an installation by Chinese photographer and artist Yang Yongliang that collages black and white photographs to mimic cigarette ash. The tip of the huge cigarette sculpture hangs vertically in the installation space, and when you look closely, you can see images of the city skylines layered upon one another. Yongliang's background in Chinese calligraphy and Shan Shui painting is unsurprising given the level of intricacy and detail involved in both that are also evident in this installation.
