I'd be very interested in this information also! I have no photoshop experience yet but itching to try some HDR shots in the near future and was wondering about the motion question also when you're taking several shots back to back with different exposures.

Cool...will get started on it. Not sure the process will have HDR in the ACR instructions. If you want HDR blend tutorials I have one here on the site.
