Louis was sound asleep as he was carried into the Chapel Royal by Kate for the christening ceremony at the Chapel Royal at St James's Palace which lasted 40 minutes. And it's clear to see why the Londoner, who has shot everyone from Ryan Reynolds to Jennifer Lawrence, is one of the world's most renowned portrait photographers.
While the Queen and Prince Philip were not present in the photos, The Duchess of Cambridge's family took centre stage.
Prince George's 2013 christening photos were taken by Jason Bell, a celebrity photographer who has snapped stars including David Beckham and Kate Winslet. Louis was dressed in a cream, frilly lace royal christening gown - a replica of the intricate robe made for Queen Victoria's eldest daughter in 1841.
The ex-actress can be seen standing in between Harry and Camilla while beaming widely.
Mr Holyoak said: 'I was truly honoured at being asked to take the official photographs at the christening of Prince Louis, and to witness at first hand such a happy event. Louis' great-grandparents, Queen Elizabeth and Prince Philip, were unable to attend the christening. Lucy Middleton - a cousin of the Duchess of Cambridge - read from St. Mark 10: 13-16 and Guy Pelly read Ephesians 3: 14-19.
Elegant and colour-coordinated, the Royal Family were captured in the morning room and garden at Clarence House, the London home of Prince Charles and the Duchess of Cornwall. "I only hope I have captured some of that joy in my photographs", Holyoak told The Daily Mail.
The third photo zooms even further, focusing on just Louis' immediate family-the Duke and Duchess of Cambridge and their three children, George, Charlotte, and, obviously, Louis himself.
They're then joined by William's father Prince Charles and wife Camilla, his brother Prince Harry and his new wife Meghan, as well as Catherine's parents, sister Pippa along with her new husband James Matthews, and her brother James.
