Lodz gives up its ghosts in rare photos

A set of highly moving and rarely seen photographs of life in Poland's Lodz Ghetto are being exhibited at the Nazi Documentation Centre in Cologne.

The photos were taken by the prisoners themselves and capture scenes of everyday ghetto life, such as community dances and boys working in a factory.

There are also horrific images of execution and trains carrying prisoners to their death in the camps.

Until now, the photos were stored in 27 albums holding more than 1200 photos in the state archive at Lodz.
