LIGHTING? – FOR WHAT?
In video production, and photo film and in theater lights are used to highlight, highlighting, etc … to cut figures or objects that are part of the scene.
You can use many types and sources of light, natural or artificial. But we take care of the artificial, and its infrastructure systems.
In light sources, there are many kinds and types, but we will deal with its functions:
Mainly there are three functions lighting scene:
These lights or spotlights whose function illuminate the characters, and there are two types of functions: those that give a soft spot light, base, and harsh lights, or raising relief, or “shape” Figures in a two-dimensional medium 2, enhancing traits to something like 3 dimensions. Normally, they will warm lights or bluish white, but always basically white, with a touch of color.
These lights are tasked to illuminate the sets or cyclorama. Their mission is to create an attractive effect, in terms of light and color, which enhances the decor and help integrate it into the image. They can be mild or occasional, depending on the set and the intention of the director of photography, or enlightening. They can be indistinctly white color, although color are the latest trend.
As the TV medium in two dimensions, 2D, if the scene should be left as is, it seems that the main figure and the set are in the same plane. It would appear that the figure is embedded in the set.
To avoid this, bathes behind the main figure, with a halo of light, which creates a profile on the shoulders and head, literally “off the main figure of the set. This is more important, the closer you are the main figure and decorated.
normally this point for projectors, fresnel type allowing direct light well, and cut to avoid unwanted bouncing elements are used.
Here are a few touches of the main idea, and that of course supports all kinds of variations in different situations and preferences “wizards of light” as cinematographers, and illuminators.
LIGHT PROJECTORS- FEATURES
Anything that produces light is a lighting projector.
Could be the Sun, a candle, a window, or something artificial, as the projectors.
In a spotlight, we have to take into account several parameters to gauge their suitability or otherwise for the function to which it is assigned.
Power consumption. And therefore the consumption efficiency of light generation.
The light produced. Measured in lux or footcandles (approx. 1 candel = 10 Luxes).
Type yoke. Whether simple or it can be operated from the ground by pole.
The color temperature. Normally 3,200 or 5,600 Kº.
Type lens. Par, fresnel convex plane (PC), aspheric, or without lens.
Type of protection in the lens, if necessary. This protection is used if tungsten lamp explodes.
Production technology of light. HMI, Tungsten, LED, Phosphorus.
Weight and dimensions. Not the same use in field production, which will be transported by hand many times, that if you will be hung from a rack without moving.
Allowing the battery power or mainstream. To ENG battery is very convenient.
