If you're putting together a photography project, there's nothing like having ambition. Bleeding London is a concept from the Royal Photographic Society London and aims to catalogue a photo from every street in London — 73,000 of them — by 31 October 2014.
It's inspired by Geoff Nicholson's book Bleeding London, in which a character called Stuart London walks all London's streets. Nicholson himself says it seems "an utterly improbable idea, which is to say I also thought it was a brilliant one". They've got 18,000 pics to date, so quite a way to go, and partly why there are meetups organised to go snapping (try the one this Sunday in Brixton).
It's not just for fun. There's a competition with a camera and society medals up for grabs, and RPS London will host an exhibition next year with one photo from every street. Every participant is guaranteed to have at least one image in the exhibition.
Photos must have been taken after 7 March 2014. Upload them to the RPS website and, of course, have a browse to see if your street has made it in yet. (If not, you know what to do.)
