This is not a painting! The image above is a photo by Frank Krahmer (see the image larger). I saw this pop up on Reddit and had to investigate.
Listen beautiful relax classics on our Youtube channel.
The image is from Namib-Naukluft National Park which is part of the Namib Desert (considered the world’s oldest desert according to Wikipedia). I found a similar image on National Geographic which gives you a sense of the scale of the dunes and camel thorn trees. The image below was shot by Frans Lanting.
