I witness
Increasingly the well-known pictures of significant events around the world, such as the bombings in London on 7 July 2005, are coming from citizens rather than professional photographers.
The shot taken of the immediate aftermath of the Tavistock Square bomb was widely publicised in newspapers and on the BBC. The judges of the award were unanimous in choosing it as the winner.
Vicky Taylor, BBC News Interactivity editor and one of the judges, said: "I went with the pictures which were taken by people almost by chance. They did not set out to photograph an event, it just happened in front of them."
Ian Reeves, editor of Press Gazette, said "It's clear from the quality of the entries to these awards that citizen journalism, however you define it, is going to play an increasingly significant role in the industry."
The person who took the Tavistock Square photograph elected to remain anonymous and asked for the prize to be donated to one of the London bombings charities.
The third prize went to another photograph taken of the aftermath of the 7 July bombings. The image was taken by Alexander Chadwick in the tunnels of London's Piccadilly Line as commuters made their way to a station from the bombed train.
To be eligible for the award, pictures had to be taken between 1 May 2005 and 20 April 2006. They also had to have been published in a known magazine, newspaper or broadcast or seen on a self-published blog, citizen journalism site or photo-sharing service.
