I've never really tried "advanced" pp stuff... Could you do that kind of stuff with just a single shot? Or do you need to have multiple exposures?
CS5 can make HDR from single shot too .. it's more or less what I tried to do to correct my sample.
There is more or less 12 EV in Canon 5D MKII RAW files (14 in Nikon D7000 and Pentax K5) ...
Unfortunately I noticed, you can't extract the 12 EV with DPP, but with CS5 (and I suppose RAW Therapy too) you can do it..
