The protest was against police abuse of Section 44 of the Terrorism Act 2000, which the photographers claimed has become a blanket measure to harrass and intimidate photographers lawfully going about their business.
Between 1,500 and 2,000 people gathered in Trafalgar Square, almost all armed with a camera. As usual, some fringe groups including the Socialist Worker propaganda sheet and the blogger Old Holborn were present, but the majority seemed to be ordinary photographers, from all walks of life.

With the exception of that one incident, which was met by hundreds of cameras, nothing else of note could be said to have happened. The group began dispersing to the pub at 12.30pm, although a few hundred hung around to take pictures of each other. There was some light press coverage of the day.
