The winners of the 2013 Sony World Photography Awards have just been announced. Norwegian photographer Andrea Gjestvang was announced as the Photographer of the Year, for her series of portraits of children and youths who survived the July 2011 massacre on the island of Utoeya, outside Oslo. This year's contest attracted more than 122,000 entries from 170 countries. The photographs were judged in six different competition categories, including Professional, Open, and Student Focus.
