While clouds are integral to these images, they can be capricious in desert climes. I chased this majestic formation across the landscape, circling back to make multiple exposures. In this particular frame, all the elements line up in consummate balance – the foreground cloud shadow punctuating the horizon line, motion blur at the edges with sharpness towards the center, a couple of rectangular road signs placed just so – nature, human endeavor, and happenstance all convening to perfect advantage.
