Hmm, very true when I think about the HDRs I've seen, first thought I usually have is "man that's amazing, how can that be?" and then in my head pops in "oh HDR". There are some HDRs that have been done that are pretty stunning and look surprisingly natural, but those are few and far between these days (and I am completely unable to produce these yet). As for Dragan, a lot of new DSLR students at my university have basically draganized all their portraits, sadly they take this as their own style
The ND filter does give the natural look, and since OP is looking at them now it seems like the logical choice. I wonder if people use HDR with reason so that it looks more natural like an ND, but then again, what's the point just buy the ND and save some precious time.
