The light illumination the sheet from behind is truly what makes this photograph. It silhouettes the tree and allows the gust of wind to turn it into an extension of the undulating shape of the tree, like a massive unified piece of foliage. The filter used to darken the sky and the flowing sand dunes tie the picture together allowing for interesting shapes from one border to the next. I picked this image because of the use this strong use of light. It is a feature that I strive to achieve in my own work, and one that when present, really makes a photograph.
