Night on the Boulder River

Photograph by John Warner , National Geographic Your Shot

While hiking and camping in Montana's Beartooth Mountains, Your Shot member John Warner used a technique called light painting to illuminate the landscape as the Boulder River roared by. "It was pitch-dark and actually cloudy, hence the Morse code star trails," he writes. "During the five-minute exposure I walked upstream along the river's edge carrying two powerful flashlights." Through gaps in the foliage, Warner shined beams of light onto the water and the opposite bank as he walked. "I wish you could hear the deafening sound."
