I remember that afternoon well, we had beautiful fluffy clouds all over the sky that were moving fast. As a result the light on the dunes kept changing all the time. I captured this in the brief moment there was light on the field in front of us but part of the dunes were in shadow, makes a nice contrast with the sky.
