While on an extensive road trip this summer, I found myself in Great Smokey Mountains National Park. I happened upon a rock in the middle of a river in the park that was not being over run by water. With a steady amount of moisture provided by the river and defused light of the forest the rock was growing a healthy green moss garden. Although the top of the rock was being lit by defused light, the side of the rock was in dark shadow. I set my camera on a tri pod and grabbed a flash light I had on hand. I bracketed several exposures and used an increasingly longer exposure time. Using the flash light I "painted" light into the shadow of the rock. I was successful with the longest exposure and consider it luck that I was able to balance the artificial light with the natural light. The long exposure also allowed the natural light reflected in the turbulent water to be rendered like brush strokes on a canvas.
