I normally use photoshop to do my HDR, and then tonemap afterwards in a program called luminance. Unfortunately I don't have photoshop installed on the desktop right now. So I had to create the HDR in luminance, and then tonemap it there as well. Luminance, does a...ok job at creating a HDR image. I think the dirty skyline is a result of tonemapping a poor HDR file.
As far as the silhouette look, I was going for that indeed going for that. The Halo'ing is a result of the operator used in tonemapping.When I get photoshop installed I'm going to re-do this
