HDRI and IBL Rendering

The main idea was to superimpose CG elements into a real photograph that might be interesting at sight. So I came up with the idea to have some well-known monuments into an Atlanta scenography. By using IBL, I could be able to achieve good rendering quality without spending too much time tweaking lights.
