Dawn at the Dunes
Dawn is the time that marks the beginning of twilight before sunrise. It is recognized by the appearance of indirect sunlight being scattered in the atmosphere, when the centre of the Sun's disc reaches 18° below the horizon. This dawn twilight period will last until sunrise, as the diffused light becomes direct sunlight. Here a fellow photographer is atop a dune taking advantage of the warm indirect light.
