David Harp has been photographing the delights and dilemmas of the Chesapeake Bay for nearly four decades, and his images of the Bay’s landscapes and people, flora and fauna, have been published worldwide. He prefers the marshy edges, where land and water meet and where the Bay’s above-water life is so apparent. He also seeks to work during the day’s edges—from first light to sunrise and from late afternoon into dusk—searching for subjects bathed in warm light and with long, revealing shadows.
