Three-point lighting is a standard method used in visual media such as theatre, video, film, still photography, computer-generated imagery and 3D computer graphics. [1] By using three separate positions, the photographer can illuminate the shot's subject (such as a person) however desired, while also controlling (or eliminating) the shading and ...
A background light is used to illuminate the background area of a set. The background light will also provide separation between the subject and the background. [1] Many lighting setups follow a three-point lighting or four-point lighting setup. Four-point lighting is the same as three-point lighting with the addition of a background light. [2]
Lightning is a natural phenomenon, more specifically an atmospheric electrical phenomenon. It consists of electrostatic discharges occurring through the atmosphere between two electrically charged regions, either both existing within the atmosphere or one within the atmosphere and one on the ground, with these regions then becoming partially or wholly electrically neutralized.

Sympathetic lightning is the tendency of lightning to be loosely coordinated across long distances. Discharges can appear in clusters when viewed from space. [22] [23] [24] [clarification needed] Upward lightning or ground-to-cloud lightning is a lightning flash which originates from the top of a grounded object and propagates upward from this ...
Representation of upper-atmospheric lightning and electrical-discharge phenomena Discovery image of a TLE on Jupiter by the NASA Juno probe. [1]Upper-atmospheric lightning and ionospheric lightning are terms sometimes used by researchers to refer to a family of short-lived electrical-breakdown phenomena that occur well above the altitudes of normal lightning and storm clouds.
A lightning detector is a device that detects lightning produced by thunderstorms. There are three primary types of detectors: ground-based systems using multiple antennas, mobile systems using a direction and a sense antenna in the same location (often aboard an aircraft), and space-based systems .
