Kathryn Costello is a portrait artist specializing in head shots, magazine-style portraiture and dance photography. This exhibit of her night photography—stars and dancers (most of whom were photographed outside after dark) uses time to illustrate what cannot be seen with the naked eye.  Whether it is freezing motion at 1/5000 of a second or a three-hour exposure to burn onto film the motion of the night sky, Kathryn captures the fleeting and the eternal.
