During a hot summer hike, the photographer's adult son was cooling off in the cool pool below Dog Slaughter Falls. Dog Slaughter Falls, on Dog Slaughter Creek, is in the Daniel Boone National Forest in Whitley County. The photographer use an ultra wide angle (14mm) lens. The exposure was a balancing act. The photographer attempted to slow the shutter down enough to emphasize the movement of water but not so much as to excessively blur the swimmer. A signed release form is available upon request.
