Abstract shot of a bridge structure and lighting on the Thames south bank.

I can't remember which bridge this is, but I'm sure many Londoners will recognise it! I took the photo on an evening walk along the South Bank in March last year. Not having my tripod, I had to use a high ISO and wide aperture. I leaned on some railings for balance as I took the shot, which was directly above me.

Camera/lens settings: ISO 1600, f/5.6, 1/60s, 22mm, hand held.
