While taking photographs with a drone you must not forget to first make sure that the place is safe for flying with drone. You must not have trees and buildings as obstacles and neither should you fly them over people. Use common sense to make sure everybody on the ground is safe.
You must be aware that the drones are of different qualities and that is going to affect the quality of your videos and photos. The DJI Phantoms are the cheapest, most available and most used drones, but for high end picture quality you will need the professional model or a high quality camera and that is going to cost you more.
