This week's photo was taken a few years ago in Sossusvlei in Namibia.
As you can see from the soft light, and the long shadows, it was still early in the morning. The red dunes, for which the Sossusvlei area is known for, were still fast asleep. No disturbances yet of (other ...) tourist. This allowed me to capture their beautiful lines.
In post, I slightly increased to contrasts to put more stress on the lines of the dunes.
