“Artist of the light”. While shooting sunrise in the Vermilion lakes area of Banff national park, Canada, I met a fellow photographer on the scene. Most of the time, we tried not to get in each other's way, however, just by accident, I snapped a picture with him in it working on his tripod settings, and it turned out to be a great photo compared to my sunrise shots.

In this Thursday, December 1, 2016 photo, Cat Bigney, part of the Oglala Native American tribe, waits on the shore of the Cannonball river for travelers to arrive by canoe at the Oceti Sakowin camp where people have gathered to protest the Dakota Access oil pipeline in Cannon Ball, N.D. So far, those at the camp have shrugged off the heavy snow, icy winds and frigid temperatures. But if they defy next week's government deadline to abandon the camp, demonstrators know the real deep freeze lies ahead. Life-threatening wind chills and towering snow drifts could mean the greatest challenge is simple survival. (Photo by David Goldman/AP Photo)
