And what about the line between real and fake in Jackson’s own work? I’m struck by a photo in her digital archive, sitting in the middle of her ‘real’ portraits (Jackson is also a portrait photographer): Benedict Cumberbatch, looking playfully squiffy as he pees into a giant pan in a restaurant kitchen. That can’t possibly be real – can it? And, if so, why haven’t I seen it before?
She says it’s from a lunch. ‘Ben got into the kitchens at The Ivy, stood up on the counter, and we quickly grabbed the soup vat for him to pee into,’ she says. ‘Of course it’s not real pee,’ she says, ‘but it’s a great picture nonetheless.’ Forget the pee, though, is it really Cumberbatch? She insists it is. The truth, apparently, really is stranger than fiction.
