This waterfall is actually a turbulent stream rushing downhill. I express its turbulence by placing it in my frame as a diagonal slice through a lush landscape. The light bounces off the leaves at lower left, skims the huge rock in the middle of the channel, and comes to rest on the opposite bank. I shifted my vantage point to make sure the large leaf hanging next to the rock soared free as if it were a bird, instead of merging it in to the other leaves on shore. It energizes the entire image.
