Nadir camera rigging that utilizes more than 2 lenses to capture 360º footage, the nadir location follows the same logic as the astronomical definition in that it is located opposite of the zenith, or in the same direction as the gravitational pull in relation to the camera rigging. Nadir The nadir (, ; from / ALA-LC: "naẓīr", meaning "counterpart") is the direction pointing directly "below" a particular location; that is, it is one of two vertical directions at a specified location, orthogonal to a horizontal flat surface there. Since the concept of "being below" is itself somewhat vague, scientists define the
Nadir and the sun is 90 degrees below the horizon. This only occurs between the Tropic of Cancer and Tropic of Capricorn at solar midnight. The tropic circles experience this once a year on their winter solstices and all other tropical regions experience this twice. The term nadir also applies to video footage produced for use in Virtual Reality aka 360º video. Cameras capable of capturing spherical footage are generally mounted on a tripod or extension boom that sits directly below and perpendicular to the horizontal plane of the camera lenses (when using two, 180º FOV lenses). In the case of
