The Royal Photographic Society (RPS) has invited photographers to take part in what it describes as one of the most ambitious photo projects ever attempted.

The RPS has embarked on a mission to collect at least one photo from every London street over the next six months.

The Society says it was inspired by a character in a book called Bleeding London, who embarks on a mission to walk every street in the capital – armed with a London A-Z.

The RPS plans to showcase the resulting images in an exhibition and book next year.

Anyone can take part and the photos can be captured on any type of device.
