Moonset. The shot was taken at Livadia, Viotia. At the foreground, Elikonas mountain. This is a nice example of an 'earthshine' photo. The visible part of the Moon is 'burned' from the over-exposion and the less visible is illuminated from the Sun's light that reflect from the Earth to the Moon's surface.
