Saturday, September 22, marked the start of autumn in most of the world (and the start of spring in the southern hemisphere). We celebrated the change of seasons with a global photo project.
Your assignment was simple: Any time on Saturday, use your mobile device to take a photo that illustrates your outdoor surroundings. The photo could be a landscape, skyline, street or action shot -- but we asked that it be shot horizontally and have no filters.
We asked people to tell us the kind of phone used to take the photo, time it was shot, as well as what the weather was like that moment.
The best shots were showcased on CNN as part of "Our Mobile Society," an initiative examining the impact of mobile technology on our lives.
