Drones can help get a good picture, if you like photography you will have fun playing with a drone. Even a cheap one is fine. I lived off a building at 4th and Wall St in Belltown and got roof access a few times.
I have a couple of really nice drones, but they're FPV racing quadcopters. I suppose I could just strap a 4k video camera to them and then pick out stills. But your picture makes me want to get an actual photography drone. That picture is amazing! I showed my wife, and she agrees, it's a stunning photograph.
