Well, here's the full story.
I was hoping the light was going to be low enough that I'd be able to keep the shutter open for a second at a time. Here's the problem though. . . because the traffic was soooo bad I literally ran out of time and had to pull over on the side of the road and run down to the beach and then try to get to a spot that wasn't crowded by people. I actually had to roll up my jeans and set the tripod out in the ocean in order to get a semi clear POV.
I had planned on stacking ND filters and stopping the lens down all the way to give me the shutter speeds that I wanted, but by the time I got everything set up and fired a few test shots (which weren't anywhere near 1 second at all. . .) the shuttle was already going off. So all I could do was just start clicking away and hoping to get SOMETHING that didn't suck.
When I got home. . . fail. F/22 against a clear blue Florida sky just showed how fucking dirty my sensor is and how badly I need to clean it.
I really should have just taken the damn ND's off and shot the thing at f/8 and called it a day. Argh.
