Marcus Bleasdale has spent his life in places most of us would struggle to imagine, photographically documenting conflict zones and communities caught in the crossfire of politics and profit.

In this conversation within The Photowalk show, Marcus talks about the responsibility of witnessing brutal truths, from child labour in the Democratic Republic of Congo to the mining of conflict minerals used in our phones and tech, and how his book The Unravelling, forces us to reckon with the uncomfortable fact that everyday convenience often comes at someone else's expense.

The mailbag is back and in today's: Spike Boydell sends in a film link that had me properly thinking about connection. Jerilyn Owen shares how making a self-portrait is helping her learn acceptance. Samantha Ramsay finds something spiritual in photographing hands, while Greg Picone stumbles across a spooky landscape right behind his own backyard. Randy Bullerwell's been capturing carnival season in Aruba in a way that's anything but ordinary and Complaints Corner is open again… this time, it's a case of the wrong pants. Plus, a quick reminder: it's the final week for this month's One Word Assignment, set by Claire Thomas.

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