Actually, it is. Just not your typical HDR image. It was created from a single RAW file versus multiple files. Sort of pseudo HDR.

 erm... no... this is not good HDR at all, it's overcooked. HDR stands for High Dynamic Range, and while this does seem to do that, it's WAYYYYYYYYYYYYYYYYYYYYYYYYY over processed

 I think most people know what HDR is. No need to state the obvious. Also, some people like the look of "over processed" HDR images. Thankfully, photography is an art, not an exact science. Otherwise we would have a bunch of the same looking photos. How boring would that be?

 Thanks, I used Photomatix Pro.

 I use it too or PS cs4 HDR merge and tonemapping plug-in.
