This picture captures contrast in size (obviously). Color through the black and white highlights. Texture in the dogs hair. Orientation from the rule of thirds. Also a few laws of simplicity apply here #7 Emotion, the photo seems to invoke feelings of funny/happiness. #5Simplicity and complexity, It is simple but I am trying to imagine what the dogs are thinking, also different dogs would give a different feeling. #1 Simplicity through thoughtful reduction, its very simple yet the photo possesses some thought to give that emotional feeling.
