I thought I'd give an example of HDR photography so people can understand a little better what it is I am talking about. So here are three photos I took of The Heigold House in Louisville. It's just a facade of an old house that sits in the middle of Frankfort Avenue where it meets River Road.

This one is a "normal" exposure, what the camera judges to be correct. There are some deep shadows inside the doorway, but other than that I kind of like it.

 This one is overexposed but you can see some of the colors and details that were lost in the shadows in the first shot.

This one is underexposed and shows the details in the areas that were too bright in the other two shots. In my opinion this is the most important shot.

This last shot is the combination of the other three. It is completely unadjusted in Photomatix Pro, so it is just the three images with no more correction But even at this basic phase you can see the details and the shadow much better than in the originals.

Of course I can play with the colors and saturation a bit more from here and come up with something a little more dramatic.

And here is the finished product. Bright colors and good detail.
