The BBC has produced a powerful audio slideshow which documents the experience of Press Association photographer Lewis Whyld when he reported on the riots in Tottenham on 6 August.

The slide show, displayed on the magazine section of the BBC News site, uses Whyld’s own images and audio accountof his “baptism of fire” in covering the riots.

He describes the scenes he witnessed and how he dealt with covering such a hostile environment, often using just his mobile phone to capture images.

Later this afternoon BBC Radio 4 will broadcast “Picture Power: Portraits of five leading photographers”, the second of five programmes looking at photographers who captured images of “the most dramatic events of the past year”.
