His examples are impressive! (at a pixel-peeping level anyway... I find this stuff just doesn't show up in prints.)
I'll end by adding, I've long said that the popular technique of HDR processing from a single raw image processed to +/-2EV then run through HDR software is not going to buy you anything but HDR artifacts, like softness and haloing. Some people may be processing specifically for these artifacts, and indeed may identify that "diffuse glow" look with HDR. For those of us who strive for a natural look out of HDR processing, this technique doesn't buy anything that you couldn't get from careful processing of the original NEF.
