Earthshine is sunlight reflected off the Earth onto the Moon, softly lighting up the dark side of the moon.

You can see this phenomenon every month just before and after a new moon, providing the skies are crystal clear and the sun has set. I’ve tried to catch it on photo dozens of times during younger phases of the moon (smaller crescent) but the weather usually messed things up.

Tonight however, the skies were clear and although the moon is getting too fat already, the Earthshine effect was still visible and I took two moon photos from the backyard, laying one shot on top of the other: one exposed for the bright side, the other for the dark side, showing Earthshine.
