The shutter speed on the first image was 0.3 seconds and the ISO was 800. The shutter speed was too fast to catch the movement of the sea oats in the breeze.
I like how this image caught the breeze. The shutter speed was 0.8 seconds, a little slower than the first one. The ISO was 400. With a slower shutter speed in this setting, the ISO of 800 let in too much light in which blew it out. I didn't waste your time by showing it.
Another lesson here. If I had taken the tripod to the beach that evening, I could have really, really slowed the shutter, and there would have been little or no camera shake. But I didn't and I can live with that. Now I just have to do some enhancements and it'll be ready to mat.
