I'm no HDR expert but these shots don't appear to have been made with the standard HDR technique of stacking exposures. I didn't see anything stating that he'd used HDR in the article text either.

There's a couple of shots that look like they might been exposed for the night sky with soft flash used to light the foreground. e.g. the cars art installation and the desert tree.

If they had been made using standard HDR techniques I would have expected the street lights not to have blown out quite so much.

I could very well be wrong though, as I said, I have only a passing knowledge of HDR. If anyone knows for sure I'd love to hear about the techniques used.
