His work caught the attention of art director Marc Ascoli, who commissioned Knight to shoot the 1986 catalog of Japanese designer Yohji Yamamoto in collaboration with Peter Saville.

[4] In 1992 Knight took a year-long break from fashion photography to work on an exhibition at the Natural History Museum, London with the British architect David Chipperfield.

[13] Also in 2016, Knight's hand-coated pigment photographic work, Tatjana Patitz for Jil Sander, 1992 sold for an artist-record $304,204 at Phillips Hong Kong.

The celebrated photograph from Knight's commercial career in the fashion industry represents the collectability of his painterly works to buyers in the world of fine art.

[17] In 2021, he reunited with Gaga for a collaboration with Champagne brand Dom Perignon on the campaign "The Queendom", in order to realize a series of photos as well as an advertisement, which was released on 6 April.
