Apparently the above picture is actually real! It looks like a blatant photoshop creation at first, but according to National Geographic it's a raw photo with no filters or any effects used to manipulate it.
On the National Geographic site it describes the photo as:
" Tinted orange by the morning sun, a soaring dune is the backdrop for the hulks of camel thorn trees in Namib-Naukluft Park."
The photo was taken by Frans Lanting who works for National Geographic. You can find more of his work on his website.
And here's a random video of the week.
