I would like to shoot a timelapse from a balcony, with the camera facing at a 90-degree angle towards the ground. Given that the balcony has railings, I need to find a way to extend the camera horizontally by about 1 meter from the tripod ballhead, so that I can rotate it towards the ground with nothing obscuring the view.
What's the standard way to do so? Is there an extension rail I can screw on top of my tripod that would safely hold the camera in place?
