The Royal Photographic Society are encouraging Londoners to document their historic city.
‘Bleeding London’ aims to tell the story of every street in London. The RPS want pictures which capture the character of the entire city, from the heart of Westminster to the outer reaches of the suburbs.
Contributors needn't be professional photographers or even have flashy gear – even a mobile will do.
The project currently has 30,000 snaps but hopes for far more to complete the project.
