My friend just got a drone and we though it would be fun to freehand some images in the sky. The process is harder then we expected. Well his job (flying the drone) was harder. My job was easy, all I had to do was to take the photo. I just had to tell him when I started taking the photo and then end the exposure when he was done. He had to draw something in the sky without being able to see the lines. Drones are not the brightest light in the sky so if you attempt this you will want to use an open aperture and a long shutter. I suggest using bulb on your camera because you get to choose when it starts the exposure and when it ends the exposure. This will depend on the camera make and model but most cameras will allow for at least a 30 minute exposure using bulb. Once we get a little better at freehand I think we try this again. Actually we may look into taking a more accurate rout by programming points in first and let the drone fly itself. For now, though, this is fun and I highly suggest you get out and try it if you have access to a drone.
