Just before sunset when the sun is just hovering above the horizon. It was stormy on the north rim which meant lots of clouds would be traveling through. With the clouds breaking apart, beams of light would make their way to the canyon floor creating a mosaic of canyon walls, buttes, and temples. Shooting into the sun allowed the contrast to show through as well as the depth that is not truly seen from the rim. Using a medium telephoto lens allowed me to get a more intimate shot of the light playing amongst the canyon walls. Truly, a spectacle to be seen.
