[CR] Shining Moon Light on the Sea
The moon has no light of its own, so that it can shine.
The rays of the sun are reflected on the surface of the
moon and due to this the moon appears to be shining.
Since the Moon is spherical, the part of the Moon illuminated
by the Sun appears as a crescent.
Photo with Nikon D5000
I strongly recommend to open the photo in a separate tab to appreciate it.
