Pictures can make a difference. You can make a difference. You just have to know when and where. If you were going to take the picture for your personal enjoyment, that'd be horrible. If you were to take it in a journalistic sense, to show people not only what happened but what can happen, and if doing so would make a few people (or just one) wake up and drive more carefully, that's something splendid.
I just came back from Romania. I photographed some things I wish I had not even seen. But I know why I did it.
The kid on the left is mentally handicapped, the boy on the right has a skin disease. They have no homes. And there were many, many more kids like these. They live under bridges, in the sewers, at the railway station. During the day they beg, steal and sniff glue.
I wanted to take them to a hospital and pay for them to get proper treatment. Maybe I could have paid for two, or three, or even four or five of them. But I didn't. Instead I talked to them, laughed with them, cared about them... and photographed them. I know that once this series is finished, once I've compiled a documentary with photos and text, and once I show this documentary to the public, more money will be raised, and these kids will get proper care; not two or three of them, but who knows, all of them?
At the moment itself it is hard to press that button. Very hard.
But sometimes... you know exactly why you are doing it. And who you are doing it for.
