1. Feeble human eyes require a certain level of light to see color. Cameras, though, have the magical ability to expose the world at night. Husband-and-wife photographers Diane Cook and Len Jenshel have been playing with long-exposure photography for years — more specifically, in moonlit gardens.

    National Geographic magazine hired the couple to shoot a series specifically for the March issue. Even more photos, including a few from their personal archives, are on display at the magazine’s headquarters in Washington, D.C.

    The stars have to align for one of these photos to turn out — almost literally. “Moonlight has its own soft, romantic poetry,” the couple writes in a National Geographic dispatch, “but to get it right when photographing a garden at night requires some hard science.”
