Nothing seemed more important to me than to make the world aware of the senseless death and starvation in South Sudan. I wanted people to see through the eyes of the suffering so my photos might motivate the international community to act.
Don't expect things to happen fast. Be empathetic with the people you are photographing. Don't be concerned about money.
Obviously I am a photographer and I believe in my medium: I do think that powerful photographs can force change. It doesn't take long to look and be engaged in a strong image whereas, with a story, you have to actually sit down and pause and be involved in it.
I've seen so many photographers rush to do books the minute they start shooting, but one great thing about photography is that the images don't go away, so the more I sit with these images, the more I learn which ones have had the most impact.
Photography of any living being, according to Taliban rule, was illegal. So when I went to Afghanistan, immediately I was worried about photographing people. But it was what I wanted: to show what life was like under the Taliban, specifically for women.
For me, it's more about being there, bearing witness to history, bearing witness to what's happening, what our country, the position our country is taking overseas. I want policy-makers to see the fruits of their decisions, basically, and to try and influence foreign policy.
For a journalist who covers the Muslim world, we have responsibilities to be familiar with that culture and to know how to respond to that.
I remember the moment in which we were taken hostage in Libya, and we were asked to lie face down on the ground, and they started putting our arms behind our backs and started tying us up. And we were each begging for our lives because they were deciding whether to execute us, and they had guns to our heads.
I wanted to continue doing my work, but I had to figure out how. And so what I have basically come up with is that I still go to Afghanistan and Iraq and South Sudan and many of these places that are rife with war, but I don't go directly to the front line.
You have two options when you approach a hostile checkpoint in a war zone, and each is a gamble. The first is to stop and identify yourself as a journalist and hope that you are respected as a neutral observer. The second is to blow past the checkpoint and hope the soldiers guarding it don't open fire on you.
I was kidnapped by Sunni insurgents near Fallujah, in Iraq, ambushed by the Taliban in the Korengal Valley in Afghanistan, and injured in a car accident that killed my driver while covering the Taliban occupation of the Swat Valley in Pakistan.
The truth is, the difference between a studio photographer and a photojournalist is the same as the difference between a political cartoonist and an abstract painter; the only thing the two have in common is the blank page. The jobs entail different talents and different desires.
Sometimes when I am photographing a major news event, I am suddenly overwhelmed by helplessness.
One day I am at home, watching dramatic images of Iraqi Yazidis fleeing for their lives being aired nonstop on 24-hour news channels. Days later, I am there, staring at tens of thousands of displaced Iraqis and feeling a 35-millimeter frame cannot capture the scope of devastation and heartbreak before me.
To me, it's so much about doing your homework, going into a situation, getting to know the subject, making them feel comfortable, getting intimate access, getting access to all different aspects of people's lives so that I am essentially telling an entire story and not just a single image.
I think when I started going to war zones and started covering humanitarian issues, it became a calling because I realized I had a voice, and I can give people without a voice a voice... and now it is something that sits inside of me every day.
I think it's important to have perspective and to look at what you don't necessarily want to see.
