I talk with street art and graffiti historian Roger Gastman about photographer Martha Cooper's pictures of NYC's subway art of the 80s, featured in her new book Spray Nation. Also, I 'doorstep' a special photography friend in England's Lake District and there are letters on making the last pictures of life next to the first pictures of a new life, getting up at silly o clock to make friends with the best light of the day, and the punk rocker who has swapped drum sticks for long exposure photography on a Scottish remote island.
