Canadian explorer, photographer, filmmaker and international speaker Jill Heinerth joins me today for a bumper edition of The Photowalk podcast. We talk about the medical importance of our oceans, cave diving, incredible creatures beneath the waves, swimming with Polar bears and the story of a sub-marine diving mission into and iceberg. Also today, the why of making sketchbook pictures, the nostalgia of vintage prints, plus mentor and street photographer Valérie Jardin returns to launch this year's monthly Visual Stories features, which in 2024 is all about photographic feature making, starting with ONE CENTURY. 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. WHY: A Sketchbook of Life is available here.
