During the first days of the lunar cycle the Sun illuminates a small part of the Moon, making it visible. At the same time, the Sun illuminates the Earth and, like in a billiards game, the Earth reflects sunlight on the Moon, allowing the hidden area to be glimpsed. That weak earthshine reflected from the Moon is the ashen glow. This series of photographs shows, for five consecutive days, the same duality: the part of the Moon illuminated by the Sun and the part of the Moon illuminated by the earthlight. The visible and the invisible, the obverse and the reverse, the yang and the yin.
