Description:It's a delicate procedure. But with volunteers like Satoko Kinno, thousands of photos lost when a massive tsunami hit Japan last year, are being restored. Police, fire fighters, rescue workers and citizens collected them after searching through the rubble. Kinno realises how much one photo can mean to its owner. The photos are first frozen to stop bacteria and mold from growing. Then they get scrubbed and cleaned of the mud, dirt and oil left by the massive wave.(1:46)
