He also has a TV show about nature photography on cable. Some of you may have see it but not checked out his portfolio. Here it is.

Here is some black and white note sure if this is on the primary site or not. from the B&W Magazine collection

Yes, very beautiful images.
Going by the rich detail and colors, I'm guessing they are HDRI's .....at least 3 images combined (eg +/- 2ev, with one "right-on")
in Photoshop or a dedicated app like Dynamic Photo HDR, Photomatrix, etc.
