The World Photography Organisation has announced the 2015 Sony World Photography Awards’ L’Iris d’Or/Photographer of the Year recipient. U.S. photographer John Moore was named the L’Iris d’Or/Photographer of the Year and was awarded a US$25,000 prize and the latest Sony digital imaging equipment. Chosen from among the winners of the 13 Professional categories of the competition, his series Ebola Crisis Overwhelms Liberian Capital documented the tragic spread of Ebola in Monrovia, Liberia, which was the epicentre of the epidemic. The judges stated, “John Moore’s photographs of this crisis show in full the brutality of people’s daily lives torn apart by this invisible enemy. However, it is his spirit in the face of such horror that garners praise. His images are intimate and respectful, moving us with their bravery and journalistic integrity. It is a fine and difficult line between images that exploit such a situation, and those that convey the same with heart, compassion and understanding, which this photographer has achieved with unerring skill. Combine this with an eye for powerful composition and cogent visual narrative, and good documentary photography becomes great.” German photographer Armin Appel won Open Photographer of the Year and was awarded US$5,000.
