Aerial Photography is a skill best learned by both study and practice. There is no better way at learning than by taking pictures and reviewing your work, but you need to be prepared before you go and know the basics. I am certainly no pro at this myself, but feel that I am improving, and I created this small infographic that I hope can help beginners getting better, and understanding aerial photography with a drone.
Before you can master taking pictures from the sky, you need to have the equipment capable of delivering the kind of work you want. You need a quality drone and a quality camera both. Check out my recommendations for great drones with cameras.
To keep improving as a drone photographer I recommend that you keep studying and learning tricks from the pros. When you combine the knowledge you can get from them, with a great camera and a drone, you have a great hobby or even the start of a new drone business.
