GPS is burgeoning into a tool for more than just finding our way, such as choosing gears on a weekend drive. If one of Google's newly published patent applications becomes reality, positioning might also fix our off-color photos. Its proposed technique would use GPS to automatically tune a camera based on both the local climate and whether or not you're outdoors: the white balance and saturation could be different for a sunny day in the park than a rainy day stuck inside, for example. While automatic settings are already commonplace, the method could lead to more accurate output that reduces the urge to flick on a manual mode. There's no guarantee that we'll ever see the patent in a shipping product, but don't be surprised if future Android smartphones produce uncannily good photography with little effort.
