Thanks Gene. Actually I didn't use Color Efex on this one. I used Photomatix for the blending and then most of the edits were done in LR.
The sky appears a bit gray and darker up too. That's from the mesh metal roof, not HDR blending.
Great work Alfredo. I love this scene. In Photomatix did you start with one of the presets...would like to know what settings tricks you gravitate towards.
