This new photography book in collaboration w/ Calvin Klein is not like any other book you’ve seen before. It features photos by Mario Sorrenti, Yoko Ono, Ryan McGinley, and Inez Van Lamsweerde & Vinoodh Matadin.If you’re reading this book indoors, the cover and all phots will appear in black and white. However, if you take it outside, the sunlight will activate all pictures and color will be splashed onto all the photos. I’d like to try this out myself but then I would have to buy the book… there’s only 3000 limited edition copies!
