Take a look at this lovely abstract. There's a secret engrained in its paint and lines. Can you see what it is? Look at it for a little while, see if you see what is hidden, and then scroll down for the answer.
The secret is that this is not a painting at all -- it's a picture taken by National Geographic photographer, Frans Lanting in Namibia’s Namib-Naukluft Park. Lanting took this extraordinary picture of a small grove of camel thorn trees against a red sand dune (dotted with white grass) reflecting the early morning sun. Absolutely no photoshop was involved!
