Drones, more formally known as unmanned aerial vehicles (UAV), are essentially flying robots. They can be remotely controlled or can fly autonomously through software-controlled flight plans in their embedded systems working in conjunction with GPS.
Drone photography makes it possible to capture images and video content that might not be otherwise possible for human photographers and videographers. Drones can be equipped with computer vision, face recognition, gesture recognition and and artificial intelligence (AI) that makes it possible for them to follow the user while they walk around or travel in a vehicle and respond to commands. That capacity could be especially useful for drone journalism.
