The King was among those returning to official engagements, along with the Duke and Duchess of Edinburgh.
Traditional official portraits marking the crowning of Charles III and Queen Camilla were released on Monday evening.
The King and Queen were photographed together and separately in their full regalia, but also joined a party of working royals for a group shot.

It featured 12 members of the Royal Family in total, including the King and Queen; his sister, Princess Anne, the Princess Royal; Prince William and Kate, the Prince and Princess of Wales; and Prince Edward and Sophie, the Duke and Duchess of Edinburgh.
But who are the other five lesser-known royals in the portrait?
1. Edward, Duke of Kent
Prince Edward, Duke of Kent, 87, and the late Queen Elizabeth II were first cousins through their fathers. Edward's mother, Princess Marina of Greece and Denmark, was also a first cousin of Prince Philip, making him both a second cousin and first cousin once removed to King Charles.
Edward is currently 40th in the line of succession to the throne.
He has held the title of the Duke of Kent for more than 80 years and is involved in more than 140 charitable organisations.
Until 2021, he was president of the All England Lawn Tennis and Croquet Club, making him a familiar face to tennis fans as he presented trophies to the winners at Wimbledon.

Born in Denmark, Birgitte, Duchess of Gloucester, 76, is the wife of Prince Richard, Duke of Gloucester, Queen Elizabeth's cousin.
A full-time working member of the Royal Family, Birgitte is linked with more than 60 charities and organisations across the arts, the military, sport, health, welfare and education.

3. Prince Richard, Duke of Gloucester
The youngest grandson of King George V and a cousin of Queen Elizabeth, Prince Richard, 78, was fifth in line to the throne when he was born in 1944. He is now 30th in the line of succession.

4. Vice Admiral Sir Timothy Laurence
The retired Royal Navy officer, 68, is the husband of Anne, Princess Royal, the King's sister.
