“Hidden History: The Lost Portraits of Bradford” available on BBC iPlayer

Hidden History: The Lost Portraits of Bradford is a BBC film made in collaboration with Bradford Museums and Panos photographer Tim Smith.

It explores how the Belle Vue Studio’s extraordinary portraits were rescued from a damp cellar to reveal the city at a time of extraordinary change, filtered through the lens of a Victorian camera that sat immobile in an unchanging daylight studio for over fifty years.

It is available to view on the BBC’s on-demand iPlayer site until the 1st July.
