I'm walking this week with photographer Mali Davies in cultural Liverpool, birthplace of The Beatles, looking for the city's famous Liver Birds and challenging ourselves with low-light street photography, and as we're focusing on street photography, mentor Valérie Jardin returns for her monthly series, Visual Stories. Also today, letters from the mailbag; finding your why, how photography is a great passport for friendship, and the most incredible detective story about finding someone from a 1930s photograph bought within a collection in a London shop. Links to all guests and features will be on the SHOW PAGE as always and my sincere thanks to mpb.com who sponsor this show and the Extra Milers without whom we wouldn't be walking each week.
