Eleven new photographic portraits of Queen Elizabeth II have gone on display - including one by the Queen's second cousin, the Earl of Lichfield.

The Earl was present for the unveiling of the photographs at London's National Gallery on Friday.

The other portraitists include rock star Bryan Adams, singer of the 1991 smash hit Everything I Do (I Do It For You).

The Canadian singer, who is a successful amateur photographer with several published books to his name, was originally due to appear at the exhibition but withdrew because of illness.

Others in the exhibition include David Secombe, son of the late comedian Sir Harry, press photographers Polly Borland, Julian Calder, Fiona Hanson and style photographer Rankin.

Lord Lichfield's portrait of the Queen with the Duke of Edinburgh was created using digital technology to fuse two separate profiles.

'Prior approval'

The Earl described himself as "a great believer" in digital photography.

"The Queen saw me putting the picture together before I left and so I got prior approval for the portrait.

Fiona Hanson: Captured a "cheerful expression"

"I like profiles because they are interesting.

"I took a stamp and a coin and looked at then closely with a magnifying glass and the picture was based on that view," he said.

Fiona Hanson, who has covered the Queen's duties for the Press Association for the past four years, portrayed the monarch in front of a 1771 portrait of George III by Johann Zoffany.

George III one of just five monarchs to have reined for more than 50 years.

Ms Hanson said she was pleased to capture "a relaxed and cheerful expression".

"The Queen's expression makes or breaks the picture regardless of props or background.

"The Queen has always got so much on her plate - and this is sometimes reflected in pictures."
