Roger Mayne's photographs capture 1950s street life

Roger Mayne was one of the pioneers of so-called "humanitarian" photography.

He turned his lens on daily, commonplace interactions between people and places, with his most famous series capturing the lives of residents of the run-down Southam Street in west London.

His photos are being exhibited for the first time in nearly 20 years - in The Photographers Gallery in London. Karen McQuaid is one of the curators.
