Interesting shots and lightings....can you explain to me the principle difference between HDR photography and normal photography?

I do 3d illustrations with a realistic lighting simulations and camera. It just interest me to know if these effects can be simulated virtually. Im getting tired of typical architectural illustration look that floods the papers nowdays and looking for some fresh style to start with.

Thanks in advance!

I would say that knowledge of Photoshop (or other equivalent) software is very much a must in this era of digital photography. Photoshop itself does support HDR, but PhotoMatix gives better effects when it comes to tone-mapping.

I do have plans to come up with a writeup on this one. But I hope my skills would mature a little bit more before I do that.
