With keen insight, Yang Yuanyuan captures invisible traces and blurred coordinates in ever-changing urban environments. Places like construction sites, cold parking garages, sparsely populated zoos, and abandoned restrooms are restored to sight through her photographs. The installations and photographs exhibited in “Interval” all manifest the artist's concern for human society and the environment. Yet this preoccupation is not derived from her romantic imagination, but through her practice of fieldwork. In addition to photographing original images, she re-presents existing materials that are recovered as found images. These two types of visual material subtly intertwine to construct the artist’s imagined world.
