Methods and apparatus track an object with a first camera causing a second camera to also track the object. The object is a moving object. Geospatial coordinates, including an elevation or altitude of a camera are determined on the camera. A pose of the camera, including a pitch angle and an azimuth angle are also determined. Azimuth is determined by a digital compass. A camera pose including pitch is determined by accelerometers and / or gyroscopes. Cameras are communicatively connected allowing to display an image recorded by one camera being displayed on a second camera. At least one camera is on a movable platform with actuators. Actuators are controlled to minimize a difference between a first image of the object and a second image of the object. Cameras are part of a wearable headframe.
