Nothing Adrian Warren and Dae Sasitorn have seen through their camera lenses could be more rich and varied than their latest subject.

Flying in a Cessna 182 from a tiny airstrip in a Somerset field, the conservationist film-makers and photographers have captured all 9,000 miles of the British coastline, resulting book in a book called The Living Coast.

From the World Heritage Jurassic cliffs of Dorset and Devon to the gannet-haunted Scottish isle of St Kilda, their seagull's-eye views show a remarkable, ever-changing, world.

The varied geology provides a rich palette of colours, from the red sandstone cliffs of Devon to the stunning white dunes of the Outer Hebrides.

The West Country holds its own among the 376 images.

A view of Minehead picks out the peaked white "tent" of the Butlins building, while the old fishing town tumbles down from the rolling hills of Exmoor, and more modern streets drive straight lines across the landscape.

The images are dramatic and the accompanying text by Christopher Somerville, one of Britain's best-known travel writers, adds another rich vein to the book.

He explains how the shot of Somerset's Watchet Harbour illustrates the perennial access problems of the Bristol Channel.

At low water, the harbour, enlarged in the 19th century to export iron ore from the Brendon Hills, dries out, and the marina is inaccessible from the sea until the tide turns.

The Living Coast is published by Mr Warren and Miss Sasitorn's company, Last Refuge Ltd, at £14.99.

Author and photographers will share their experiences in making the book at Stanfords, Bristol, at 7pm on Tuesday, December 2. To book ring 01179 299966.

A book launch will also be held from 6.30pm-8.30pm on December 4 at Waterstones, Wells.
