Duffy together with David Bailey and Terence Donovan is recognized as one of the innovators of "documentary" fashion photography, a style which revolutionized fashion imagery and furthermore the fashion industry. So influential were their images that in 1962 the Sunday Times dubbed Duffy, Bailey & Donovan the “Terrible Trio” and Norman Parkinson further added to their notoriety by naming them "The Black Trinity". Together they dominated the London photographic scene, constantly pushing each other to new heights. Even socially they would spend many hours together talking, living and breathing photography. He also did some pretty iconic work in the seventies too, including this ever-so-slightly recognisable album sleeve from 1973.
And a series for the 1973 Pirelli calendar which he created in collaboration with British pop artist Allen Jones and air brush artist Phillip Castle.
