light sources in a city at night are all artificial. they provide a stable lighting situation in comparison to daytime, when clouds, shadow or sun position are always changing.

here I remembered the saying that light works like a splash of water - it emerges from the source, then hits nearby surfaces and rapidly weakens the further it gets away from the origin.
