Chip Clark started work as a photographer at the Smithsonian National Museum of Natural History in Washington, DC, in 1973. With his background in biology, it proved a rewarding position, so he stayed put for 37 rewarding years, gaining expertise in macro photography, infra-red and ultraviolet imaging, and high-speed and time-lapse cinematography. Along the way, he accompanied staff on research trips to diverse locations, from the Peruvian rainforests to the Caribbean seabed. Since his death in 2010, a more personal project has attracted attention and praise—portraits of the museum’s archivists taken over the course of nearly 20 years, depicted amid the collections they care for.
