An agency that has been providing news content for 40 years, I think Paul Walters, former news photographer, now leading the line at SWNS today, returns for his second instalment and is a strong candidate for helping us understand the place of a photographer in news today. What is the role of a news agency, what qualities do you need to be a contributing professional photographer and is citizen photojournalism changing the shape of how the industry works? 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.
