Auto bracketing is perfect for creating HDR images. But in the end, it does require manual work to make it look good.
I use Photoshop CS3 Extended. I find that a true multiple exposure bracketed HDR image is limited to static landscape/architectural type images with the use of a tripod.
However, you can do "pseudo" HDR with RAW images. RAW images captures a good deal more dynamic range than a processed JPEG. So, you can usually recover or extend highlights and shadow detail that is normally tossed out with a processed JPEG.
Basically in Camera Raw, move the exposure and brightness slider controls to get the sky or ground details (at the expense of other parts of the image). Do this a couple of times (2-3 versions of the same image will usually suffice). Then just shift+drag all the images into one, use layer masks to hide the areas you don't want in each image version. For instance, one version has the sky nicely exposed, but the ground and shadow areas are too dark. You would mask and hide the ground and shadow areas. On another layer, there is a version where the ground and shadow areas are nicely exposed and brightened, while the sky is completely blown out to white in many areas.
HDR is kind of a gimmicky term for a technique of merging multiple images that has been around for a long time.
As Edwood has mentioned, it is possible to create a HDR from a single raw. Just play ard with exposure settings via PS. I do that and merge using Photomatix.
But even then it is not considered by purists as true HDR because it lacks the real dynamic range of multiple-bracketed shots.
Then again, it is useful for creating HDR shots of scenes with moving objects in them.
Here is one of my earlier efforts creating a HDR from a single RAW file.

while we are on the subject of raw, what exactly is the difference between in-camera processing and software processing when speaking about exposure. when you take a raw image, cs3 or the camera bundled software will let you adjust the exposure as post process. I assume that is the same thing that is done in camera when you take a jpeg- except with raw, the extra information is still available to rebuild the image within a range of exposures. what is the difference

RAW files are saved at 16bit while the jpg is in 8bit. With a jpg you are left with only 256 levels of brightness. A Raw file has the full range of the cameras chip available to you.
How did you take three identical shots without using a tripod?
No caffeine whatsoever and meditating for three hours before shooting.

Okay, okay, infinitesymphony, I've been caught. I probably have more caffeine than blood in my veins most of the time....
Yes, diredesire hit it on the head--it's an auto-align function (in Photomatix in my case). If you look closely at the edges of the Photomatix HDR image I posted, you'll see just how off I was, as I didn't elect to crop off the edges (and so you can see just how off I was).

I may have to try that.

Yeah, Ed, but "HDR" is so much easier to say and spell than "ATOMMITHBAFALT."

Good point.

That's a very nice result. I'm really going to have to try that single-image RAW method.
