A candle burning in the photographer’s home in Fort Collins, Colo. on July 8, 2019. The motion of the flame on the left was captured at 1/8 shutter speed. Then, the light was turned off, and the flame on the right was frozen with 1/15 shutter speed. This photo was taken as an experiment in creative shutter speeds for a digital photography course at Colorado State University. Photo by Brooklyn Matlock. ISO 200.
