The Queen's Christmas message will be broadcast to the Commonwealth in 3D for the first time.
Behind-the-scenes footage, released this morning, shows Queen Elizabeth II in 3D glasses - studded with Swarovski crystals in the form of a "Q" - watching the recording with her production team.
Set in the White Drawing Room of Buckingham Palace, the Christmas broadcast pays tribute to her nation's Olympic and Paralympic athletes.
She reportedly hails the "splendid summer of sport" and highlight how the sportsmen and women allowed spectators to feel part of the "excitement and drama".
The message was recorded earlier this month and shows the Queen wearing a fine silk tulle gown by Angela Kelly.
Her use of 3D technology comes 80 years after George V first broadcast a Christmas speech on the radio and started the 25 December tradition.
A Buckingham Palace spokeswoman said the monarch thought the broadcast was "absolutely lovely".
"We wanted to do something a bit different and special in this Jubilee year, so doing it for the first time in 3D seemed a good thing, technology-wise, to do," she said.
The message will be transmitted on both television and radio at 15:00 GMT on Christmas Day.
It will be available on the Royal Channel on the YouTube website and will also be shown in Commonwealth countries.
