New York City portrait photographer Bill Wadman is back for the final time today in his three parter. We talk invention and how for some photographers, like Bill, it's the unknown, it's the learning, that keeps you creatively fresh. The story also of how Richard Avedon approached his studio portrait work and how he captured a particular infamous portrait of the Duke and Duchess of Windsor in an unconventional manner.

Today's show is kindly supported by MPB, trading thousands of cameras and lenses every week across Europe and the US. MPB checks, grades and photographs every single item, and adds a six month warranty, so you can be sure of what's in the box.
