Along Highway 72 just east of Traverse City behind the Turtle Creek Casino. This field is only planted to sunflowers in some years.
Contrary to popular belief sunflowers do not follow the sun. This was taken pointed toward the west, but the sunflowers are pointed east.
I had been watching this field of sunflowers for a couple of weeks. The light was just about right and the flowers were near their peak. I used a graduated neutral density filter to hold back some of the light in the sky. It still required some Photoshop work to lighten the shadows and to darken the clouds.
