Abstract: Embodiments of this application provide a pan-tilt, a method for controlling a pan-tilt, and a photographing apparatus. A magnetic-field generating apparatus for generating uniform detection magnetic field is mounted on a pan-tilt base of the pan-tilt, a conductor rod is mounted on a pan-tilt head of the pan-tilt, and two ends of the conductor rod are electrically connected to a voltage detection unit. In this way, in a process of the pan-tilt head rotating relative to the pan-tilt base, the conductor rod cuts magnetic induction lines of the detection magnetic field and generates an induced electromotive force. In addition, in the embodiments of this application, the induced electromotive force on the two ends of the conductor rod can be detected through the voltage detection unit.
