HDR using a single RAW

This is a interesting topic since it need quite a lot of setup to take multiple exposure of the same scene (at least a tripod). If this can be done using single RAW file, the possibilities is unlimited to me.

Using samples from photomatix

↑Normal

↑HDR

My testing

↑Normal

↑HDR

↑HDR after PS retouched

Of course the result is not quite satisfactory, need a more dramatic scense to practice and moreover, the raw should be shooted slightly underexposed

If not using photomatix, using Photoshop CS3 can also produce the HDR result but oc need more steps and work :
