“People will fly to Europe to look at the adoration which Rembrandt, Caravaggio, La Tour paid to light—they will stand in awe in the center of that great vaulted room of colored glass, the Sainte Chapelle, but at home, if martinis are waiting indoors, they will not slow down to look as the grass around the door turns incandescent in the setting sun. And there’s a lot more sunset grass in our lives than Saint Chapelles or paintings in museums… One film, entirely devoted to what light can do to ordinary stuff, is called Hurrah for Light!” —Ralph Steiner
