It is definetly a balancing process. I think overcooking looks best when you can get some clouds and sky in there, as that will add a lot of drama. Plus, I think it helps to turn down the saturation quite a bit. I may have pushed it too far with this image, but I am hoping to do a much better shoot later where I'll work more on keeping those tones that were lost to black. That said, I think overcooking is where you'll see HDR really come alive, and we'll probably start to see a lot more of it in mainstream advertising and media as folks get more used to the look. Just like reverb was considered an error at the advent of the electric guitar, then later spawned a whole new sound (Rock and Roll etc.), I expect what looks like an error today will be embraced as a whole new branch of photography.
