No it doesn't. That exposure control dialog is simply a post processing effect. It's just like the levels/brightness and contrast/exposure controls in photo shop. It is absolutely the wrong method to do HDR.

The exposure setting on the camera tells the camera shutter how long to stay open for so the light can be exposed on the CCD. The raw control doesn't magically re-expose the image by moving that slider and RAW does NOT take multiple photos to get multiple exposures for this "exposure" slider. You can go test this for yourself, go take a photo in raw and listen to the shutter, you will only hear it once!

We need a sticky to tell all you people that you can't do HDR from a single photo. Heck, its even in the name; High Dynamic Range. Using the same photo 3 times doesn't change the dynamic range! Hopefully all the 1 photo HDR bull can stop!
