The royal family's photographer revealed his favorite photos of Queen Elizabeth and Prince Philip

• Queen Elizabeth died on Thursday, September 8 at the age of 96.
• In 2021, following the death of Prince Philip, royal photographer Chris Jackson shared his favorite photo of the royal couple.

Britain's Queen Elizabeth II — who ascended to the throne 70 years ago and died at age 96 on Thursday — was photographed with her husband of 73 years, Prince Philip, countless times. But for Chris Jackson, who has photographed the royal family for more than a decade in his role at Getty Images, there's one image that stands out.

Jackson captured the couple sharing a laugh with Prince Charles and Camilla, Duchess of Cornwall as they watched a game of tug-of-war at the annual Braemar Highland Gathering in Scotland in September 2006.

Jackson initially shared his favorite photograph of the royal couple in a moving tribute in April 2021, following Philip's death at the age of 99.

"Hands-down still my favourite picture of HM The Queen, The Duke of Edinburgh and The Prince of Wales at an event they clearly enjoy and were so relaxed at, The Braemar Highland Gathering," he wrote on Instagram. "This spectacular and friendly event takes place just down the road from The Queen's summer residence of Balmoral."

Jackson told Insider in 2018 that the Braemar Highland Gathering "is a great opportunity to capture the royal family at their most relaxed," making the 2006 image his "all-time favorite."

"Over the years, I have a huge amount of favorite moments," he said. "While the tradition and formality form an integral part of what it means to be a royal, it is their interactions that remind you these are brother and sister, mother and son, sister and brother."

On Thursday, following the announcement of the Queen's death, Jackson took to Instagram once more to share another favorite snap of the Queen.

"Capturing The Queen's unique, sometimes enigmatic and always heartwarming smile has been the focus of every opportunity I've had to photograph her over the many, many years I've been lucky enough to do so and that's why this photo will always be one of my absolute favourites," he wrote.
