Picture This

You're deep within the confines of a government-run camp of football fanatics, deep within the jungle without your camera. Suddenly, you find a block of wood with a small pin-sized hole in it, a roll of black tape, two pieces of black cardboard and a canister containing 1 roll of Kodak Tri-X ISO 400...

It doesn't look like the projects are that extreme, but Picture This sort of seems to work this way. They setup a weekly project, you read the brief summary, grab your camera and interpret it however you want and then upload your best shot. The Picture This community critiques your work and you continue to improve your shot building your portolio in the process.

Oh, and it's powered by Flickr, which makes it even easier to get involved with.
