The Duke and Duchess of Cambridge have asked the photographer who took widely-praised 70th wedding anniversary images of the Queen and Prince Philip to get back behind the lens for Prince Louis' official Christening photos today
British-born Matt Holyoak, considered to be one of the world's best portrait photographers, will capture Louis' with his close family and godparents following the private 40-minute ceremony this afternoon
The traditional religious ceremony is to take place at St James Palace with many of the royal family - with the exception of the Queen and Prince Philip - expected to be in attendance
Scroll down for video Holyoak's star is clearly in the ascendant; he has had a number of his pieces of work acquired by The National Portrait Gallery for their permanent collection, and has donated photographic prints to many exhibitions across the world
Many of the world's biggest A-listers have struck a pose for Holyoak including Gary Oldman, Ryan Gosling, Sir Ian Mckellen and Frances McDormand
His stylish photos are regularly splashed on the covers of magazines such as Harper’s Bazaar, Shortlist and Dazed and Confused and he's shot powerful campaigns for charity, including Cancer Research, the Haiti 'Are You Here' campaign and Mental Health campaign 'I Swear'
Last year, however, he got the call from Buckingham Palace asking him to prepare for perhaps his biggest challenge yet - taking official images to mark the 70th wedding anniversary of The Queen and The Duke of Edinburgh
The photographs were taken for Camera Press, which also celebrates its anniversary 70 years after the agency distributed the royal pair’s official wedding photos as its first assignment
Holyoak began his love affair with the camera at art college where he eschewed fine art - and a talent for still life - in favour of capturing objects and people on film
