It does not matter how turbulent the surface of a body of water is; it does not matter how strong the waves are or how numerous the ripples. If a dark filter is held over the lens and the scene exposed not for the hundredths or thousandths of seconds but for seconds or even minutes, that turbulent surface becomes smooth and tranquil. The waves vanish, the ripples disappear.
You see, in the absence of light, time brings tranquility to turbulence. In times of pain and sorrow, the only balm is the tincture of time.
