I loves me a bit of street photography, so when the details of a December-long contest specifically for street photographs landed in my inbox, I sat up and took some notice. Especially when it's a comeptition that respects photographers' rights (the rights remain yours; all yours) and has a decent prize to boot!

It's been organised by Thomas Leuthard, a Swiss photographer whom you might happen to know by his moniker 85mm. He takes some impressive street photos and wanted to inpsire others to have a go, too. So came about the December 'Headlines' competition.

Yep, all photographs need to include a headline of some description. It can come from a newspaper, from a shopfront, from a carrier bag... whatever. Being a street photography contest, they need to be candid shots, which is pretty obvious, really. And it has to have been taken in December 2011, too.

Thomas has also added a couple of extra rules to get you to think about your photography a bit more. All entries need to be black and white and square format.

When you've taken your photo, you submit it to the 85mm contest pool on Flickr, with its EXIF data intact, geo-tagged using the Flickr widget, and without any watermarks. It's one submission per person and then its a case of waiting.

The pool will be closed on 31 December 2011, after when Thomas and the four other judges will choose their favourites, with a $500 prize going to the winner.

All the rules and regulations are up on Thomas' site, and if you've any more questions, he'll answer them over in the discussion threads in the Flickr group.

What are you waiting for? Get snapping!
