The back half of the lunar sphere is illuminated (i.e., the side facing the sun, which you can see had set in the lower left of the photo).
A crescent sliver of that illuminated half is visible from your perspective.
A large portion of the half of the moon that is not receiving direct sunlight is visible from your perspective.
That half of the moon is slightly illuminated by "earthshine" – i.e., indirect sunlight bouncing off the earth and back.
