Wildflower Center Cistern Roof
The Lady Bird Johnson Wildflower Center in Austin is a wonderful place to visit. I headed down there this afternoon for a couple of hours and took a tripod to try some HDRs. The wind was a bit too strong to get good outdoor shots (too much movement between the exposures) but this one turned out quite well.
This is taken inside the viewing tower at the visitor centre using a very wide angle lens.
