Today, I chat with Balwinder Bhatla, AKA Mr. Whisper, a London-based visual storyteller and professional photographer. Bal specialises in delicious candid low-light street photographs, taking us on walks where the urban landscape transforms into a very different kind of place, where every pool of light or mysterious shadow becomes a photographer's muse. He has shot stories in his style for BMW, Netflix, Google and Disney, including making a series of pictures to promote Star Wars Rogue 1. And it all started when his wife commented, "The cool kids are using this app called Instagram."

Also, on the show and from the mailbag, Mat Bobby has the most incredible personal story of how showing some pictures on a wall led to a life friendship with his photographic hero. There's a Haiku from Chris Hughes inspired by an Australian reservoir, how Colin Mayer's Extreme Sports experience turned into a love affair with photography instead, Phil Ferris is lost somewhere in the north of England and we'll pick the flask winner from last month's assignment entries.

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