Lighting, most generally, refers to the use of artificial light to reveal the shape and form of a scene or image. This can be contrasted with natural lighting, such as daylight. In photographic and cinematographic fields, lighting sets the mood or atmosphere of the scene. In the theatre, the correct lighting can change the psychological atmosphere of a scene from comedy to tragedy, and everything in-between. The amount of light used in the scene depends on the directors vision of the scene and the emotional effect they wish to create. The tools used to light a scene are called lights and they can come in many different shapes and sizes. Some lights are designed to be very soft and diffuse, while others are designed to be focused and create dramatic shadows. Lights can also be placed further away from the subject to create a flat, even lighting or they can be placed close to create a variety of shapes and textures on the subject. Lighting is an important part of photography, videography, and filmmaking. Without adequate lighting, photos or videos can be flat, boring, and lack the mood or atmosphere of a well-lit scene. Professional filmmakers and photographers use a variety of lighting techniques to create the desired look for their productions. Lighting can also be used to create a variety of different effects, such as using bright lights to simulate the look of sunlight or using shadows to add a mysterious, dark atmosphere to a scene. By experimenting with the placement of lights and the strength of light, filmmakers and photographers can create a variety of looks and effects to enhance the overall look of their productions.
