You can watch a fantastic interview with photographer Tim Walker over at Showstudio.com. Walker speaks of his work experience at Vogue in the early 90s and the time he spent in the magazine's "dungeon" archiving old Cecil Beaton negatives.
He also talks about his disinterest in the technical side of a camera and his preference instead of the visuals; how set design and styling have influenced the trademark scenery of his photographs.
During the course of the 15 minute interview, Tim Walker also shares the postcards and images of renaissance art that inspired his editorial "A Private World" for Vogue Italia back in November 2008.
I really recommend you watch the video, even if it's only the first five minutes, he makes some very interesting points and it's fascinating to hear him talking about his work and process in so much depth.
