Very interesting visual essay on CNN featuring turkish cab driver Sevket Sahintas, who photographs the poor, the homeless and the lost during his night shift.
"I saw people on the street in winter. They were cold at night," he said. "To make their voices heard, I wanted to buy a camera and show that these people are living in difficult conditions. That's how it started."
Sahintas also takes black-and-white portraits of the other characters who roam Istanbul's streets at night: dirty street children, garbage pickers, transvestite prostitutes.
Despite the attention, Sahintas doesn't make enough money from his photos to earn a living. For that, the photographer has to work the night shift in his yellow cab.
