UPDATE - 22nd July 2011:

Still collecting photos for this one so please contribute! I'm particularly lacking in city shots. Can you help?

Original spec - 7th May 2011:

Larsène and I have been talking for a while now about pictures taken of children walking away from the camera, the innocence and wonder implied in the slant of the head or the small silhouette cast against a larger, perhaps imposing, background.

For us, pictures of our children walking out into the world inspire hope and fear in equal measure. It's what we want for them - to go forth with confidence and curiosity, to experiment and discover. But ever present are the accompanying anxieties and the fervent desire for their journeys to be ones that are coloured with happiness.

So, I'm looking for something very specific with this collaboration. No adults holding hands or shepherding them out into the world - just simple images of children (on their own or in groups) walking away from the camera. Can you help?
