Well we do multiple exposures with film too! So I don't think HDR is really cheating (it's just a modern form of multiple exposure with the freedom of tweaking).
Here is a question for you guys. What is the advantage of Nikon's Active D-lighting? I mean it's just in camera processing right? We can achieve the same thing in Photoshop (or D-lighting command in Nikon Capture)?
Attaway to dig up a months old post... this subject has been hashed over again and again, ad nauseum.
But to address D-lighting: I like it, in moderation and only with certain portraiture situations. Otherwise, I'd trust a fill flash or bracketing approach.
