I call this a cheater HDR photo because I only used one shot to generate the range. You take one properly exposed photo and adjust the exposure settings to get one with the highlight detail (under exposed) and one to get the shadow detail (overexposed). You mash them together in Photomatix and get the HDR photo above.
The only real difference is a little less detail on the ends of the ranges. You also get less of the halo seen in the last shot.
Cheater HDR is great with real-life macro because of wind and the like. It is nigh impossible to hand-hold three exposures properly for macro HDR.
So maybe less "cheater" and more "creative use of software."
Also, the flower had some weird stain on it I didn't see in the original. Funny.
