Today through Wednesday, UK photographer Nick Knight and SHOWstudio are airing a live webcast of his latest project: “Let There Be Light.” While Knight is an internationally known photographer (you make recognize this iconic image of Björk), he is also one of the most transparent, regularly exposing his works-in-progress on the SHOWstudio blog. This time he’s shooting model Lily Donaldson for V Magazine, and livestreaming the machinations behind the machine. (They’re also tweeting.)
