Never before seen, untouched photos of some of the world’s most famous stars show a rare laid-back side to celebrities in a new exhibition.

Kate Moss, Brad Pitt and George Clooney are among those included in the undoctored set of prints from a series of shoots with British photographer Andy Gotts who is one of the few professionals in his industry not to retouch his pictures.

Moss’s contact sheet shows her looking as picture perfect as any polished image, whilst Pitt and Clooney’s photographs show a jokey side as they pull faces at the camera.

The Unseen Collection also features Penelope Cruz, Kate Winslet, Robert De Niro, Harrison Ford, Benedict Cumberbatch and Julia Roberts.

Each person’s montage shows a series of photographs taken in one sitting, all untouched but with the previously shown image’s frame highlighted and the others all being shown for the first time.

Gotts travels to photograph celebrities in their own homes where they are most relaxed and leaves all of his shots exactly as they were taken to show what life is like behind the celebrity mask.
