“A Clean Line

Photograph by Zay Yar Lin

A seafarer paints the railing of a ship at sea. From the photographer’s vantage point on the bridge wing, the view seems a clever split screen — the swirling blue water contrasting with the solid, vivid red of the deck, and a meticulously clean white line dividing the two. Zay Yar Lin, who submitted this photo, explains the importance of the seafarer’s work: “To facilitate transporting merchandise around the world, the ship has to be maintained in good and efficient condition. Daily maintenance involves hard work such as chipping, scaling, cleaning, and painting.”
