Speaking after the official shoot, 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".
The royal family have released official photos from Prince Louis' christening day.
Prince Louis's christening was held last week at the Chapel Royal in St. James's Palace in London.
Her Majesty and Prince Philip did not miss the ceremony due to poor health, but mutually agreed with the Cambridge family "some time ago" that they would not attend, Buckingham Palace confirmed.

Israel launches air strikes on three Syria military facilities
Israel worries Assad could let his Iranian allies entrench there or that Syrian forces may defy a 1974 Golan demilitarisation. The army said it will "not allow any violation of Israeli airspace and will act against any attempt to hurt our civilians".
The breathtakingly handsome photos were unveiled to mark the young Prince's christening, which was attended by senior members of the royal family. One shows the duke and duchess with their immediate families.
The Archbishop of Canterbury, Justin Welby lead the service with support from the Dean of The Chapel Royal, The Right Reverend and Right Honourable the Lord Chartres, and The Sub-Dean of the Chapel Royal, The Reverend Canon Paul Wright.
One shows Kate in a garden cuddling and gazing down at Louis, dressed in a frilly cream lace royal christening gown - a replica of the intricate robe made for Queen Victoria's eldest daughter in 1841. And proud grandparents Prince Charles and Carole Middleton are standing in the center, behind the Duke and Duchess and their two young children.
In another one of the photos, Louis is awake and looks at Kate adorably, and the bond between mother and son can not be mistaken.
'I only hope I have captured some of that joy in my photographs'.
In the first shot, Louis is surrounded by both sides of his family, the Middletons and the royals, as he rests contently in his mother's arms.
