Lighting
Like the human eye, the camera cannot see well without a certain amount of light. Because it is actually not objects we see but the light that is reflected off the objects, manipulating the light on objects influences the way we perceive them on-screen. The purposeful control of light and shadows is called lighting. Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect. Lighting includes the use of both artificial lights like lamps and light fixtures, as well as natural illumination by capturing daylight. Brief History. With the discovery of fire, the earliest forms of artificial lighting used to illuminate an area were campfires or torches. As early as 400,000 BCE, fire was kindled in the caves of Peking Man. Prehistoric people used primitive lamps to illuminate surroundings. These lamps were made from naturally occurring materials such as rocks, shells, horns and stones, were filled with grease, and had a fiber wick. Lamps typically used animal or vegetable fats as fuel. Hundreds of these lamps (hollow worked stones) have been found in the Lascaux caves in modern day France, dating to about 15,000 years ago. Oily animals (birds and fish) were also used as lamps after being threaded with a wick. Fireflies have been used as lighting sources. Candles and glass and pottery lamps were also invented. Chandeliers were an early form of "light fixture". With the development of electricity and the incandescent light bulb, the luminosity of artificial lighting improved to be able to use indoors. They became widely used and extended the time that people could stay up, among other developments.

You can aim the light beam to illuminate a precise area. A flashlight and car headlights to produce directional light. In television and...
