Explanation: Single shots like this require planning. The first step is to realize that such an amazing triple-alignment actually takes place. The second step is to find the best location to photograph it. But it was the third step: being there at exactly the right time — and when the sky was clear — that was the hardest. Five times over six years the photographer tried and found bad weather. Finally, just ten days ago, the weather was perfect, and a photographic dream was realized. Taken in Piemonte, Italy, the cathedral in the foreground is the Basilica of Superga, the mountain in the middle is Monviso, and, well, you know which moon is in the background. Here, even though the setting Moon was captured in a crescent phase, the exposure was long enough for doubly reflected Earthlight, called the da Vinci glow, to illuminate the entire top of the Moon.

说明: 要取得这样的单曝光影像，需要事先规划。首先得意识到这种惊人的三重合美景真的会发生。接着是要找到最佳的拍摄地点。不过，第三步才是最难的：在天空清朗时，准时赶到地头。在6年之中，摄影者试了5次，每次都有坏天气从中作梗。最后，终于在10天前天气近乎完美，让摄影梦得以实现。这张摄于意大利皮埃蒙特大区的主题影像，前景为苏佩尔加大教堂，中间的山峰是芒维沙峰，而你应当知道背景是月亮。在影像里，尽管所拍下的是蛾眉状新月西落的景象，但因为曝光的时间够长，经过双重反射、亦名为达文西灰光的地照光，也照亮了月亮的顶部。
