Tower Bridge London, September 2005.
[FZ20: 1/500, f4.6, ISO 200]

Shot with a circular polariser to give the sky a more dramatic feel. I've converted to b&w using a green channel filter to accentuate the contrast in the image. Composition isn't perfect (the crop on the lefthand side of the bridge is unfortunate) but the overall effect is pretty much what I was after. I may reshoot the scene for a slightly better framing, now I know what mistakes I made.
