Photographer Richard Misrach and Sarah Greenough, senior curator of photographs, National Gallery of Art. Employing an aerial perspective, Richard Misrach instilled his monumental beach series with a sense of disquiet: with references to the horizon and sky eliminated, figures appear isolated and vulnerable. In the first of this three-part podcast, produced on the occasion of the exhibition Richard Misrach: On the Beach, he talks to Sarah Greenough about the influences and origins of his photographic career.
