The venue: Most venues are normally closed from the top and this would make the venue not friendly for drone photography. The time: the drones can grab all the guests’ attention away from the wedding. And it normally takes a lot more time to get a good shot and you would have to pose for each photo longer.
the weather: you have to be really cautious of the weather while using drones for your wedding. If your wedding is in the rainy season, it is advisable for you to get in touch with the weather department to know if the weather would even allow the drone to soar in the air or not.
