Late afternoon on a beautiful fall day on the middle Texas coast, I was photographing wading birds, when I turned my attention toward the western sky and noted this beautiful display of color above. I turned my telephoto lens in that direction and captured this image of what I think is an iridescent sky scene? Whatever the case, it was captivating!
