Leading photo retoucher reponds to photo of Princess of Wales

Several international news agencies have pulled a photo of the Princess of Wales, over concerns it has been altered. The photo of Kate and her three kids was released overnight by Kensington Palace, to mark Mother's Day in the UK. It's the first official snap of the princess since she had abdominal surgery in January. At the time, the palace said she would not return to public duties under after Easter. Since then, there has been wild speculation about where Kate is, and what's wrong with her. Professional photographer and leading photo re-toucher Rob Nicol, of Mac Artist NZ speaks to Lisa Owen.
