It's pretty hot and steamy here in South Beach . . . 80 degrees and humid :-)
One of the best places I have seen for HDR.
HDR tip: Think selectively. In the top image, I selected the interior print (in Photoshop) and desaturated it just a bit. Otherwise, it would have been over satured due to the interior lighting. In addition, I use Unsharp Mask only on the interior print for added impact.
Both images are Photomatix + Topaz Adjust.
