During a cloudy day visit to Chichen Itza, some sun broke through and hit the main pyramid. I bracketed 3 shots and combined to create a subtle HDR image to get the details out of the storm clouds that were forming.
I also removed some tourists in the lower right of the picture using CS5's content aware fill (I'm not happy with the result, but it's certainly better than seeing the big group of brightly dressed people).
Taken with a Nikon D90 and a Nikon 24-120mm lens at ISO 200, f8 and 1/500th second exposure.
