The pier at Santa Monica California is a great place to come and watch the sunset. It is a bit of a challenge to photograph because so many elements change so quickly. The wheel was turning at different rates, the sand getting wet and drying out, etc.
But I wanted everything just right in a single photo. And after about 20 minutes it finally came together. The exposure time was long enough to catch the wheel as it rotated exactly one spoke along, creating the impression of a lot of movement. The sand was just wet enough to reflect the wheel and the sky, and so on. I changed the settings so much that it was like playing a video game!
