High Dynamic Range (HDR) Photograph #1

A fun fact about me is that I love to travel. I took this picture on Hawaii Waikiki beach. As you can see post processing a picture with High Dynamic Range (HDR) can lead to some interesting effects. I post process a lot of images using Topaz Labs plug-ins http://www.topazlabs.com/ for Adobe Photo Shop.

This is the information on the original picture before post processing:
How I took the picture:
Camera Model Canon EOS DIGITAL REBEL XSi/450D
Lens  EF-S18-55mm f/3.5-5.6 IS
Flash Type  OFF
ISO Speed   200
Tv(Shutter Speed) 1/640
Av(Aperture Value) 20.0
White Balance Mode Auto

Definition of HDR from Wikipedia:
In image processing, computer graphics, and photography, high dynamic range imaging (HDRI or just HDR) is a set of techniques that allows a greater dynamic range between the lightest and darkest areas of an image than current standard digital imaging techniques or photographic methods. This wide dynamic range allows HDR images to more accurately represent the range of intensity levels found in real scenes, ranging from direct sunlight to faint starlight, and is often captured by way of a plurality of differently exposed pictures of the same subject matter
