This is the first of two HDR images from Barcelona. This one was taken near the Olympic stadium and the tall structure to the left of the image is a communications tower. Of the two Libby prefers this one but I think that tomorrow's has the edge.

As with most of my recent HDR images this was processed with Photomatix Pro using the Details Enhancer method (as described in my HDR images: part two tutorial, but in this case I used a three shot rather than seven shot sequence (the 5D will only auto-bracket three shots while the 1Ds Mark II can shoot seven).
