South-African photography duo Adam Broomberg and Oliver Chanarin of Broomberg & Chanarin talk us through how they've had access all areas and why they are not political artists, even though their work touches on the subject. Now blacklisted in politically-sensitive territories after shooting at Chicago, a training camp built by the Israeli Defence Force, they discuss photojournalism as well as the relationship of the photographer with his subject. Over a screen printing session in the backyard of their Shoreditch studio, we witness them preparing for their show at Saatchi Gallery where they are currently exhibiting a series called "Trouble." While questioning the veracity and revelatory powers of photojournalism, they unearthed the archive 'Troubles by the Belfast Exposed' and highlighted elements in the selected pictures, as a commentary on the events. Out of Focus runs till 22 July at the Saatchi Gallery, www.saatchi-gallery.co.uk
