HDR of a single image

Here is a before and after of our famous rainbow in DV shot. The before is tweaked as best I can in LR2. The After is post-processed using the HDR Tone Mapping adjustment in PS CS5. I'll probably try this again with Photomatix Pro sometime, as well. Apparently, tone mapping of a single high-bit image (16 bit based on 12 bit original capture) can be a big improvement. Who knew!
