One of my creative heroes is Edward Hopper's use of color, darkness, and emptiness to move the viewer's eye around a canvas.
Similar to painters, etchers, and illustrators, a photographer can also define the main subject by filling in the shadows and allowing the background ambient light to create a different way of creating mood and artistic a visual story. The color of light brings together the threads of a mystery by partially describing this woman while she carries a stylish handbag and her own plastic bottle of water. The vending machines obscure her as well as help to define her but we will never know for sure where she was going.
