Today, I walk in London with the philosophical YouTuber Sean Tucker, who shares his thoughts on what makes great street photography and the deeper philosophies behind the genre. Along the way, he talks about what he's learned from years of making pictures and teaching others to see more clearly. Also joining us is Valérie Jardin, street photographer and mentor, in Teach Me Street. She answers questions about the art of candid photography and offers practical advice on how to approach it with confidence.

Also from the mailbag, Michael Mixon reflects on the future while photographing in his parents' home, and Phil Paine shares a newly self-published photographic journal after a career spent in television. Mark Mackay experiments with seeing the world as if through a camera without ever lifting one, while Mike Miller explores the surprising similarities between streets photographed with people and those without. There's news of our new end-of-year competition, and we have a fresh one-word assignment.

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