They're beautiful but I like Walt's stuff better then those as his are as extreme as I like to see. Those are more "art" then images to me and just don't look real in any way/shape/form.
Did you see the one with the sunk boat? Walt, get to work you can do that to yours!
Different stokes but a perfectly shot image with great light is hard to beat with photoshop (just IMHO obviously)
Josh I doubt those were done "1 click" with merge to HDR!
