Lighting in TV and video light is a major commodity in video production, so his way, direction and intensity of impact on the target largely determines the quality of the final image. hal can contribute to your knowledge. Why is should follow a series of basic rules of lighting of the scene, to get to show what you want and how you want, always just Snug as possible to the initial plan of filming. Objectives: – That video cameras produce images of the highest possible quality, – get a proper light regardless of the location of the camera, – manage to create the image flat, an illusion of three-dimensionality, and all of this, looking for an attractive visual effect. For this reason, that should be taken into account factors as: do confronts the technician what light? With the parameter color temperature, determines the exact color within the existing scene light spectrum, to compare it with the light that It would generate a black body. To determine it is needed the help of a termocolorimetro. Playing with the intensity, or the amount of light emitted, is may highlight some elements more than others, creating scenes more intimate, or on the contrary, spaces with lots of light divided evenly. Depending on the direction of incidence of the light on the bodies, will be projected shadows to one side or the other, so will be important to know previously the exact location of the actor or presenter, its position relative to the camera, as well as the location of other objects which could come in plane.
It must be considered also the quality, i.e., the hardness or softness of the light used. Hard light is more intense and it will encourage good lighting but at the same time creates crisp, well-defined shadows. Soft light instead, being more subdued, never participate as main light source but Yes will help reduce the shadows produced by the harsh light. The basic triangle of illumination: A Once known the location of the subject in the scene, its orientation, the position of the camera and shooting scenario, may already constitute the basic triangle of illumination. In the first place the main light is generated (hard light) to dominate the subject, which is often placed at the top of the camera, between 15 and 45. Then put the fill light (SoftLight), with the aim of reducing the shadows of the main light, and will normally be placed on the side opposite the main light. Finally, the light of against, in order to give volume to the scene, which will be located behind the subject so that it is as opposed to the main. Original author and source of the article.
