High Dynamic Range photography is very popular for art photography, but it also has a lot of potential for commercial photography as well.
Here's an example. The first shot is a normal image shot in the gallery. The lighting in the gallery is ideal for viewing the sculpture, but not good for photography.

Now, here's the same image photographer HDR:

And a detail comparison:


If you're not familiar with HDR, the concept is simple. You shoot at least three images at different exposures and combine them to get a wider tonal range than you could get in one shot. Kinda like combining bracketed exposures.
In this example, there were three images; one normal exposure, one two stops underexposed and one two stops overexposed. The images were combined using Photomatix and retouched in Photoshop CS4.
