Chris Orwig returns for the second in this three parter. A professional photographer, mentor, teacher, speaker, Chris talks about the power a photograph has when it's 'authentic', and I, with his help try to unpick what this secret ingredient is when making a portrait in particular.

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.
