His first book of photographs, 'Skinhead', was published in 1982, whilst a student at Bournemouth.[2] He was then commissioned by i-D editor Terry Jones to create a series of 100 portraits for the magazine's fifth anniversary issue. As a result of those black-and-white portraits, his work caught the attention of art director Marc Ascoli, who commissioned Knight to shoot the 1986 catalogue of avant-garde Japanese designer Yohji Yamamoto in collaboration with renowned graphic designer Peter Saville.[2] Since this first foray into fashion photography, he has shot both editorial and advertising projects for clients including Alexander McQueen, Audi, Calvin Klein, Christian Dior, Jil Sander, Lancôme, Levi Strauss, Martine Sitbon, Mercedes-Benz, Royal Ballet, Royal Opera House, Swarovskiand Yves Saint Laurent.[2]
