Now the light is divided into "Face light" and the wedding "Side light". Weddings are the most important "face light " to ensure the characteristics of light. Then we consider "Side Light".

Explain "Face Light" and "Side Light"
“Side light is the color of the whole scene, such as LED dyeing lights, moving head lights, etc. These are often used. The lighting engineer will design according to the wedding links and themes. The point to be stated is that “sidelight” is It is used to render the environment, but not as a "face light". Some lighting engineers use the LED lamp as the main light source to shine on the person's face. First of all, this high color temperature light will make the picture are not soft, then there is the discoloration of the person's face, which makes the person's face or body "discoloration". In fact, based on the color temperature problem, most of people use PAR64 light for washing, its price ratio LEDs are cheap, and such washing is mild, uniform, real, and natural. The only downside is that the power consumption is quite high, and some sites where power is not available are used with caution.

Face light is divided according to light level
1, front light: in the horizontal position 0-10 degrees
The face of the character is very bright, and there is no stereoscopic effect. This kind of light is not suitable for the round-spun face, but it is a powerful lamp for expressing the youth and youthfulness of the character.
2, front side light: 20-30 degrees in the horizontal position
It is a good lamp position for auxiliary light, which will soften the light and enrich the level.
3, the middle side light: in the horizontal position 40--50 degrees
Often used as the main light of the character light, about 45" angle, can accurately control the distribution of light and shadow, very suitable for the position of the follow-up light.
4, side light: 60-90 degrees in the horizontal position
In the performances of the art, the side light is indispensable and plays an important role in the characterization of the actors' lines.

Easy to produce sunlight, the flank, cheekbones, forehead, and the back of the head have a high-gloss effect on the back of the head.
The texture is fixed.

Produces a continuous edge of light on the head and shoulders of the character, separating the head from the background so that the characters in the vision no longer cling to the background.
7. Foot light: The light projected from the platen in front of the stage to the stage, mainly assists the surface illumination and eliminates the shadow formed by the face and the jaw of the person illuminated by the high position such as the face light.
