About the illustration: "Fireworks in Motion" is a photograph of fireworks taken with intentional camera movement. Photographing fireworks typically requires long exposure time in order to capture the graceful arcs traced by exploding fireworks. Keeping the camera as steady as possible, preferably on a sturdy tripod, is essential to obtain those iconic shots of fireworks. However, when the camera is liberated from the tripod and is moved freely by hand against the exploding fireworks one is led to a whole new "world" of images, each reflecting a unique interplay between the moving camera and the fireworks. This photo taken with a gentle horizontal movement of camera during the 2011 July 4th celebration in New Haven, Connecticut gave the appearance that some sort of race is on.
About the artist: Zhe (Jay) Chen is a first-generation Chinese American with a degree in Theoretical Physics from Fudan University in Shanghai, China. After being selected by Nobel Laureate T.D. Lee's China-US Physics Scholarship program to pursue graduate study in the United States, he arrived at New York City and, a few months later, bought the first luxury item for himself, a Minolta X-700 SLR camera. Before finishing up the first roll of film, however, the camera was taken by someone who broke into his apartment in Manhattan. Curious about those never-seen test shots, he bought another X-700 and has since taken photography as a hobby. He is currently a medical physicist in the Department of Therapeutic Radiology at Yale University School of Medicine and Yale-New Haven Medical Center. The diversity and complexity of interplays between random motions of a subject and its observer, while intriguing and beautiful at times as shown in this photo, also reminded him of the difficulty one encounters in the delivery of dynamic radiotherapy when uncorrelated motions of target volume and radiation source are present.
