Photojournalists across the world capture the most fascinating images that open our eyes to new cultures and inform us about the world. Photography is undoubtedly a medium that unifies us and keeps the people of the world aware of one another. We recently saw the shortlist for Sony's World Photography contest that features dozens of photographers and now we bring you the winners of the 2012 World Press Photo contest. In this contest, 101,254 pictures from 5,247 photographers of 124 different nationalities were entered. Of those, 350 photos were awarded in 9 different categories ranging from contemporary issues and daily life stories to nature and portraits. Samuel Aranda's photo, above, took the big prize as the World Press Photo of the Year. Check out some of our favorites from the competition, below.
