San Dunes, Oceano, California. 1950, by Ansel Adams is an abstract photo of sand dunes that utilizes lighting and composition to create a texture and interesting angles of dark and light. Ansel Adams always shot either during sunrise or dusk when the shadows are the longest and leads to the most amount of dramatic contrast. If the sun was directly above the sand dune it would be boring and appear more flat. The shadow adds three dimensionality and perspective. The photo is split up compositionally with two thirds being a more intricate design but has the contrast of the darker stripe of the top of the dune and the blank hint of sky in the top. I really like this detail because it gives the viewer more to focus on and draws the eye up.
