Since it was released in January 2013, Twitter-owned Vine has been a tool for capturing life in the moment. Today, an update to Vinefor iOS tries to remedy that with a raft of new features for the camera aimed both at more serious and at more casual creators. The camera is also getting an optional grid, a level tool, a focus lock for the front and rear camera, a torch feature for shooting in dark settings, and ghost mode, which overlays the last frame of your previous shot on your current camera view.
