A good place to look for interesting subjects in nature is to look at the edges of change. It could be the edge of a forest, river, ocean or even the edge of a storm. Any time you can find drastic differences in nature you find edges. In this image you are looking at a river bank that at times is under water. As the water travels it wears down the small rocks and deposits them at the tree roots. This same water caused erosion which helps to expose these tree roots. I decided the subject was black & white because of the many tones the rocks and roots had. An f-stop of 16 with a wide angle lens worked best for capturing as much detail as possible. I composed the image so there would be just a hint of the tree itself because the most interesting part of this tree was it's exposed roots.
