Im not sure what an HDR shot is. The reason this shot may look unusual is because it was taken with a fisheye and 5d. I just wish I could have gone wider than 180 degrees =) I also underexposed 1 stop.

Wow! The motion that I feel in this is ominous! What a wonderful shot. Is this an HDR shot or a combination of shots? I'm not doubting your brilliance here, just curious!
