As usual, I've just picked up National Geographic, and the photos are just amazing. In this thread, I want you to post pics or links to photos that are also amazing. Not OMG HAWT MCR!1 photos, but the sort of photos that just leave you standing there wondering how they did it.
My first shout would be to Stefano Unterthiner:
First, for
This Set from this month's NG, of Penguins.
And also, these ones of
Wandering Albatrosses, my favourite birds ever.
Then, some
cool shit from some underground caves by Carsten Peter
