We like to start our Instagram-centric features by commenting on the need for a camera, or the act of ‘getting the camera ready’, but that isn’t exactly how Instagram works, is it? The phone app is all about that smart phone photography, the shots snapped before answering an important business call or checking on the Tamagotchi, or whatever it is that is cool these days. Looking for Instagram-worthy spots in Grenoble? You’re in all sorts of luck.
