A special feature-length interview episode today featuring Jason Edwards. Having spent the last three decades travelling around over 70 countries being clawed, chased, shot at, diseased, lost, injured, incarcerated, and getting his finger stitched back on, twice, award-winning photographer, TV host, and conservationist Jason Edwards knows what it takes to get the perfect shot.

And the photo editors at National Geographic agree, featuring his stunning photos time and time again. His imagery has also appeared in hundreds of other publications, including BBC Wildlife, Australian Geographic and The New Yorker. His new book, Icebergs to Iguanas features a collection of his National Geographic photographs and behind-the-scenes tales.

Also on the show today, the winning images from the last two months of assignment pictures and a new challenge for September set by Gary Williams.

Links to all guests and features will be on the showpage, my sincere thanks to MPB who sponsor this show and the Extra Milers without whom we wouldn't be walking each week.

WHY: A Sketchbook of Life is available here.
