This photo of windmills in Palm Springs, California, is about lines. There are lines crisscrossed in the chain-link fence; horizontal lines in the barbed wire; vertical lines in the fence posts; three sets of parallel diagonal lines in the blades of the windmills; and the virtual diagonal line of the tops of the windmills as they fade into the distance, which is mirrored by the line of the color change in the sky. All these lines are then contrasted by the one puffy, white cumulus cloud.
