It was night in Yellowstone National Park, and Chris Spencer was one of the last in his group still awake.
Wanting to take a few more photographs before he went to sleep, he walked to a nearby river, set up a camera and shot a 30-second exposure of the water as it flowed through a grassy break in the trees.
"The photo looked different from any other I had ever taken," said Spencer, 18, of . "It turned out way cooler than I ever thought it would."
Spencer's visit to Yellowstone last year was part of a western Wisconsin-based program that uses nature photography to help teenagers deal with behavioral or mental health issues.
The program sent teens on four trips to national parks last year, and the resulting photographs have been turned into an exhibit that is on display at the Minnesota state Capitol and will soon travel the country.
