Tower Bridge Fireworks

This was supposed to be the time I got it all right. I had the fancy high resolution camera for the big enlargements, the expensive tilt-shift lens to fix the distortion I got shooting this scene two years ago, the big nine and a half foot tall tripod to give me a clean view over the docks around the bridge, and I had Miranda there for good luck. All set up I checked the focus at 10x magnification. Sharp as a knife. But another spot about 10 feet closer looked like a better spot to set up. Sure enough it was better. Forgetting to tighten the tilting lock on the lens before moving the camera was not. The picture still looks good for the web but I was hoping this would be the one I could blow up full poster size and still be able to see every rivet on the bridge. Next time will be the time I get it all right.
