Because I don't have auto bracketing, it was windy, I was standing in a million mosquitoes without a tripod, and I was doing the best I could quickly to capture the moment in JPG. So I did the best, without having drastic ghosting. It was also one of my first attempts at bracketing a shot last spring, and honestly I haven't done many of them, since it's rare to have a windless day on the days I'm able to go out shooting. Without auto bracket, I can't dial in quick enough to prevent motion/ghosting on my d31.
I just happened to have the camera with me that day as I was driving home from work.
