This is a slightly loose challenge in the sense that lots of stuff will qualify. The main aim is to get you to use your photographic brain as much as you can and to try new things which you wouldn't have thought of before.
So the challenge then. What we want you to do is take pictures with you haven't set up. We want you to take pictures of things that you have found. By that we mean out in public, in your home, anywhere. We're talking piles of leaves that have collected in a corner, tyre marks on a snowy road. As long as you have not changed anything in the photograph, as long as you leave everything as you found it, it'll qualify. And please, try something new if you take the photo within the two weeks. Try to surprise yourself by creating a good photograph that you wouldn't normally have taken.
