Quintin Lake is my guest today, sharing stories from the literal edges. From 2015 to 2021, he walked the entire coastline of mainland Britain, covering all 11,000 km of it, creating The Perimeter, a six-year photographic journey that explores light, isolation, design, and the quiet drama of the country's outermost margins.

A fine art and architectural photographer, Quintin's eye has always been drawn to form and structure. We also talk about his personal work, including Absent Pyramid, a study of Chernobyl 21 years later, and Cold War Spaces of Fear. Quintin's work is marked by precision, stillness, and a deep attentiveness to place. In this conversation, we explore endurance and creativity, the solitude of long walks, and what it means to photograph with intention.

Also on the show today from the mailbag: Jade Lee has an idea for our 500th episode that allows you to participate, wherever you are in this world. Christopher Parsons shares how sneaking into the right place led to the shot, Bill Frische gifts us a new word you'll want to make your own, and Reed Gidez explores an abandoned hospital with a camera in hand.

Also, today, Gary Ramage invites you to take part in the new One Word Assignment for July.

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