Photographer Hugo Rittson-Thomas has produced a striking quadruple portrait of the Queen.
Using mirrors he was able to capture full-length images of the Queen from the front, back and sides, creating a picture reminiscent of Anthony van Dyck's famous triple portrait of Charles II.
In her full-length portrait the Queen is wearing a burgundy coloured dress, designed by her personal assistant and adviser Angela Kelly, with the Waterloo badge of the Royal Scots Dragoon Guards.
The photograph was taken at Windsor Castle during an event to mark the 60th anniversary of her Colonelcy of the Royal Scots Dragoon Guards in 2013.
The Duke of Cambridge and Duchess of Cornwall have also posed for the photographer and all the images will be part of the exhibition The Queen's People, featuring photographs of members of the Royal Household and senior ceremonial figures in their traditional uniforms.
Prince William, Colonel of the Irish Guards, was photographed in 2012 when he and wife Catherine, Duchess of Cambridge, joined the regiment to celebrate St Patrick's Day. He was wearing his Irish Guards frock coat for the occasion.
Mr Rittson-Thomas's project was inspired by 16th and 17th century paintings of monarchs such as Elizabeth I and her court, often painted against a black or dark background which emphasised the rich colours of the outfits worn.
The Queen's People exhibition will be held at Eleven Gallery from August 19 to September 19 in London.
