I think this is a good comparison why HDR is such a great tool for high contrast, deep shadow scenes with wide dynamic range. The first shot is the normal exposure (slightly under I guess) and the second is three shots (-2, 0,+2) and merged in Photoshop HDR option. The impact is pretty obvious. I find the PS does a better job than Photomatix blending the images and PS provides full adjustments once the HDR file is produced.
