And then, at the end of the day, I took on a little project! I noticed in a yard across the street a little ornamental windmill which, with a bit of a breeze, was spinning a little bit. I wanted to get shots showing some spin, so I knew I would need a slow shutter speed. I had my Canon 1D Mk III with me with the 100-400 lens attached, and I had a monopod, so I took that setup and went to the middle of the street and began taking shots at varying shutter speeds.
