People have been asked to vote for their favourite photo in the Royal Air Force's annual photography competition.
Judging for the 2019 Royal Air Force Photographic Competition recently took place at the Royal Air Force Museum Hendon.
More than 1,000 photos and 30 videos were entered across 13 categories, with the best nine images being whittled down by three industry professional judges.
"Every one of the hundreds of entries reminds us of the skill, professionalism and sacrifice of our serving personnel, so we’re thrilled to be supporting this competition," said Nick Bunting, Secretary General of the RAF Association.
The finalists will now compete in the People's Choice category and anyone wishing to vote can do so here.
Voting closes at midnight on 25 September, with the winner being announced on 3 October at an Awards Ceremony at the Bentley Priory Museum.
This year’s judges included freelance photographer Edmond Terakopian, Martin Keene from the Press Association and The Guardian's Jim Hedge.
Edmond Terakopian said: "The pictures on show are of a phenomenal standard."
He added that the entries included "some very well thought out photography" and some images "have required a great deal of thought" and "married creativity with timing perfectly".
Judge Martin Keene added that the RAF "have brilliantly photographers" who get to capture the whole range of the RAF’s equipment and personnel across the world.
"I have loved every minute of it," he said.
Jim Hedge said the overall standard "was extremely high quality".
