Early each year, photographers submit their work to a slew of contests, but the most prestigious is the World Press Photo. Based in Amsterdam, the World Press Photo jury goes through thousands of images—almost 83,000 this year—to name the World Press Photo of the Year and recognize the best in different categories of photojournalism. It’s a long and sometimes grueling process. And no matter which photo is named Photo of the Year, vocal differences of opinions (if not outright controversy) in the photojournalism community often follow.

This year the jury named Australian photographer Warren Richardson‘s photo of a family crossing the Serbian-Hungarian border as the World Press Photo of the Year.

Below is a selection of winners in each of the categories. Congratulations to all the photographers.

Long-term project, first place: This photo is part of a series portraying women who have been raped or sexually assaulted during their service with the US Armed Forces. Now, only 1 out of 10 reported sexual-violence cases goes to trial, and most military rape survivors are forced out of service. US Army Specialist Natasha Schuette, 21, was pressured not to report being assaulted by her drill sergeant during basic training at Fort Jackson, South Carolina. Though she was hazed by her assailant’s fellow drill instructors, she refused to back down, and Staff Sergeant Louis Corral is now serving four years in prison for assaulting her and four other female trainees. The US Army rewarded Natasha for her courage to report her assault, and the Sexual Harassment/Assault Response & Prevention office distributed a training video featuring her story. She is now stationed at Fort Bragg, North Carolina. (See more here). Mary F. Calvert/ZUMA Press, World Press Photo
