David and Louise have signed a worldwide deal with renowned image agency Robert Harding to sell their work.
The firm, which has been going for 40 years and is respected as a supplier of high quality images, will now distribute David and Louise's images to organisations that include British Airways.
Mike Watson, Picture Editor at Robert Harding, said: "When I first saw the quality of photography from David & Louise I immediately booked my train ticket as I was determined to sign them up with Robert Harding.
"Their images are thoughtfully composed and executed with great skill and imagination. They both think of the relevance of the image and the impact it will bring to whatever medium it is reproduced in either digital or printed form."
