It was windy today. There was a good solid breeze, probably about 15-20 knots, coming steady. So the flags were flying fully unfurled.
I was lucky enough to find a vantage point where I could see not one, but two, American flags, fully open in the wind. I attached the telephoto lens to the camera, and positioned myself so that the flags lined up. I tried several shots.
The background flag was holding pretty steady in the breeze. However, the wind was deflecting off a building near the front flag, making it much more erratic. At first, I tried to time the exposure. I soon gave that up and changed the settings from single shot to continuous shutter. As a result, I got over a hundred pictures in about four minutes. Fortunately, all were in focus, so it came down to selecting the one with the best lighting and composition.
Equipment: Sony NEX-5R, 55-210mm telephoto lens.
