Today, I spend time with Mike Crawford, a dynamic London photographer and master printer. For four decades he has worked with the world's most highly regarded photographers, including Martin Parr and Brian Griffin, one of the music industry's most prominent photographers.

More recently, he was chosen to print hitherto unseen photographs for the celebrated late photographer Elliott Erwitt for his 'Found, not Lost' book. As a photographer, Mike Crawford's captivating work, featuring urban landscapes and portraiture, is predominantly shot on film and crafted in the darkroom.

I visit Mike on location at his company Lighthouse Darkroom, within the building that was once home to Russia's Zenit UK operation. With the arrival of August, there's a new assignment too, set this month by social and street photographer Emily Renier, one of Fujifilm's newest ambassadors.

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.
