Drone
Drone footage gives your video a whole new dimension. But everything has its pros and cons. First of all, not every location is legally allowed to use a drone - nature reserves, proximity to an airport, city centre, etc. Secondly, I am aware of the sound the drone makes. For this reason I omit its use in the ceremony. No bride wants to say her "I do" to the distinctive buzz of this mosquito :).
So if the environment and current weather conditions allow, drone footage can be part of your final video.
