The most iconic photograph of all times  — a naked John Lennon clings like a foetus to Yoko Ono on the cover of Rolling Stone magazine after Lennon’s death. This photograph was conceptualised by portrait photographer Annie Leibovitz. She is the recorder of celebrity persona. It is hard to say  whether Leibovitz began recording history before she became a part of it, or the other way round. She maintains that to photograph someone with any degree of authenticity is to understand their life, and what makes them click. A documentary has been made on her life.
