The Duke and Duchess of Cambridge broke Royal tradition, allowing the public to take souvenir pictures and "selfies" at the christening of Princess Charlotte.
The modern move meant the event was the most public christening of a member of the Royal Family ever.
Well-wishers are normally banned from taking pictures when the Queen and her family attend services at St Mary Magdalene Church on the Sandringham Estate in Norfolk. The restriction is only lifted on Christmas Day.
But William and Kate, often fiercely protective of their privacy, asked for the rule to be relaxed, authorising people to take pictures of them with Charlotte and her brother Prince George.
