It's from hand shake. I didn't use a tripod for all of them as I wanted to be there as short as possible lol.im guessin' that some of the blurred edges is due to the HDR editing or just hand shake?
I shoot with a Nikon D90 and both. You have to either bracket 3 or more shots or use a tripod and manually switch the shutter speed to achieve a large dynamic range. Then import those shots into Photomatix, HDR Darkroom, or PS and tonemap them to get a final shot.^^^What kind of camera are you using? Are you doing the HDR in a post process program or using exposure bracketing on the camera?
Looks like he's poopin out a starre-edit
