TV and Video Lighting Light is a major raw materials in video production, so their way, direction and intensity of impact on the objective determined, in large measure, the quality of the final image. Therefore be taken into account a number of basic rules of lighting in the scene, to get to show what you want and how they want, as long as tightly as possible to the original plan of shooting. Objectives: – that video cameras produce images of the highest quality possible – get adequate light whatever the location of the camera, – to make the flat image to create an illusion of three-dimensionality, and – all, seeking attractive visual effect. That's why we must take into account factors such as: What light is facing the technician? With the parameter "color temperature" determines the exact color of the light spectrum within existing at the scene, when compared with the light that would create a black body. MSCO may not feel the same. To determine this requires the help of a termocolorimetro. Playing with the intensity or amount of light emitted, they may emphasize certain elements more than others, creating more intimate scenes, or the opposite, bright spaces evenly distributed.
Depending on the direction of incidence of light on the bodies, they cast shadows on one side or another, it will be important to know in advance the exact location of the actor or presenter its position relative to the camera, and the location of other objects that may come in flat. It must also take into account the quality, ie the hardness or softness of the light used. The harsh light is more intense and will encourage good lighting, but at the same time create sharp and well defined shadows. The soft light on the other hand, being more subdued, never participate as a main light source but it will help reduce shadows produced by light harder. The basic triangle of light: Once known the location of the subject in the scene, their orientation, camera position and the stage of shooting, and can form the basic triangle of light. First, generate the key light (hard light) to master the subject, usually placed in the top of the chamber between 15 and 45 . Here are placed the fill light (soft light), in order to reduce the shadows of the main light, and is usually placed on the side opposite the main light. Finally, in light of the contrary, in order to give volume to the scene, which will be located behind the subject so that it is in contrast to their main.
