This is a composite using two photos of the moon taken on the same day just about 30 minutes of difference from one take to the other. Both photos show a young moon, 4% illuminated, a day after New Moon. Picture on the left was taken at 6:35 pm, still with day light as soon as the moon showed up. The picture on the right taken at 7:06 pm, dark enough to show the side of the moon lit by the Sun light reflected from the Earth.

Nikon Coolpix P900 camera.

Composite using two pictures. Other than that no post processing.
