World famous artist David Hockney has unveiled the biggest painting of his career as part of the Royal Academy's Summer Exhibition in London.
The work, Bigger Trees Near Warter, is 40ft by 15ft and is made up of a grid of 50 small canvases.
Hockney, 69, created the painting for the end wall in the largest of the academy's galleries.
Light is the overall theme of this year's exhibition, which will open to the public on 11 June.
The artist - who is now based in Los Angeles - painted the piece, which also has the French name Peinture en Plein Air pour l'age Post-Photographique, in Yorkshire where he grew up.
Next month some of Hockney's new paintings of the East Yorkshire landscape will be shown at London's Tate Britain to mark his 70th birthday.
He will also help curate the gallery's largest exhibition of Turner's watercolours, including The Blue Rigi, which was saved from being sold overseas following a massive fundraising drive.
