This picture does not look like an HDR. The pink was done with lighting, you can tell because the color is burnt/overexposed at the bottom of the bridge. It was probaly a color gelled strobe or spotlight from the ground in front of the pilars.

I am better at using layers in photoshop than letting a program create an HDR image.
