"Gas drilling, regardless of one's feelings, is probably the biggest story that's happened in Pennsylvania in generations," Cohen said. "And people always want to know which side I'm on. It's very divisive.
"Everybody knows photographs don't tell the cold, unmediated truth," he said, but "there's a certain power that comes with photography."
Cohen and his group believed that photography could bring new light to a subject that has generated a great deal of heat because the images enable reflection and a multi-faceted approach.
