I just love curvilinear lines specially when Mother Nature makes them. Anytime I get the chance to capture this type of line I take it.
To me curvilinear lines are gentle, restful and relaxing, I could look at them all day long. Curvilinear lines can be found in abundance in nature. Look to streams, ocean waves, hills, the wind dancing on the surface of a wheat field or in sand dunes like this one. I hope you enjoy this photo as much as I do.
