TV and Video Lighting

Light is one of the main raw materials in video production, so their way, direction and intensity of incidence on the target will determine to a large extent, the quality of the final image.

Therefore should take into account a number of basic rules of lighting in the scene, to get what you want to display as you want, as long as close as possible to the original plan of shooting.

Objectives:

- That video cameras produce images of the highest quality possible - get a good light regardless of the location of the camera - get created in the image plane, an illusion of three dimensions, and-all, looking for a visual effect attractive.

That's why we must take into account factors such as:

What light is facing the technician? With the parameter "color temperature?, Determine the exact color in the light spectrum that exists in the scene, when compared with the light that would create a black body. To determine this requires the help of a temperature meter.

Playing with the intensity, or amount of light emitted is able to highlight some elements more than others, creating more intimate scenes, or conversely, bright spaces evenly distributed.

Depending on the direction of incidence of light on the bodies, cast shadows on one side or another, so it will be important to know beforehand the exact location of the actor or presenter, its position on the camera, and the location of other objects that may enter the plane.

It should also consider the quality, ie the hardness or softness of the light used. Hard light is more intense and encourage good lighting but also create clear, sharp shadows. The soft light instead to be more subdued, never participate as a main light source but it will help reduce shadows from the light harder.

The basic triangle of enlightenment:

Once we know the location of the subject in the scene, their orientation, position the camera and the scene of shooting, and can form the basic triangle of light.

First, we generate the main light (hard) to master the subject, who is often placed at the top of the chamber between 15 ° and 45 °. Here are placed the fill light (soft), with the aim of reducing 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 add volume to the scene, to be located behind the subject so that it is in contrast to their main business.
