Perhaps slightly less awe-inspiring, I visited Oxford last Friday and it at least did give me a chance to photograph their own 'Bridge of Sighs' although it's real name is the 'Hertford Bridge'. The Bridge of Sighs was a nickname given to it almost immediately though, and yet it resembles both the Bridge of Sighs in Venice, in the way it connects 2 buildings, but also the Rialto Bridge in how it actually looks. The building in the background and underneath the bridge is the Sheldonian Theatre.
This HDR is from 3 shots and did take quite a long time to post-process. I did a lot of layer-masking to prevent halos and 'dirty halos' (as I call them). Layer-masking also helped make the buildings in the background stand out much clearer, as opposed to the first tone-mapped version, which seemed to blur a few of the features. In all it was about 2 hours work.
