This stunning series makes brilliant use of some ambitious photographic techniques to reveal a hitherto unimagined world. Night-time photography reveals aspects of the British countryside rarely seen.

Meanwhile macro-photography allows Bill to uncover tiny creatures and plants that the naked eye would miss - and rest assured, they're just as fascinating as the big ones!

Whether he's embarking on a nocturnal quest for the country's most mysterious seabird or paddling for leaches in the Lake District, he faces each challenge with fortitude and good humour.
