I photographed this spot again and again, and the light was never the same twice. The water moves across the rocks in an unpredictable way and the sunlight was coming through leaves overhead that were also moving. I wanted this image to be all about fury. The force of the water pouring through this narrow gorge is astounding. I focused and exposed on the brightest part of the scene using my spot metering mode, which makes the shadowed areas darker and more mysterious.
