There's a new variation on doing elevated photography called Fotokite that will be available in a few months. Fotokite is an interesting approach to doing elevated photography. Don't mistake it for a drone replacement because it's clearly not. It's a tethered drone which makes it much simpler than a standard drone. This tethered approach solves a number of issues that standard drones have:
While you can't get the fantastic video that an untethered drone can get as you can see from the video above you can still get some pretty interesting shots. It has a long tether that is extra. I think it will have application in real estate photography for those that are looking for something better than a pole but simpler than a drone.
Initially, it's being sold in Europe (Switzerland) but they will ship to many other countries.
