What does the fill light mean?

Photography is the art of using light. However, natural light is uncontrollable and has a certain time limit. If you want to express your creativity better, it is essential to fill the light. Whether it is a live broadcast or a blockbuster, it is inseparable from the blessing of the fill light. A good fill light can be your right-hand man in your shooting trip, adding more color and charm to your work!

At present, the common fill lights are: photographic lights, LED fill lights, stick lights, pocket lights, spotlights and panel lights.

Among them, the photographic lamp is mainly used as the main light source to provide sufficient brightness for the face and environment of the person. Mainly used for indoor live broadcast and video shooting. This kind of lamp is basically fixed, belonging to large equipment, with special tripod and lampshade lighting tools! The requirement of this kind of lamp is that the brightness is enough, and then the color temperature can be adjusted to have enough endurance.

LED fill light can be used as both main light source and auxiliary light source. Compared with the photographic lamp, the power is relatively small, so it can be taken out to fill the light when shooting people at night. However, at present, this lamp needs an external mobile power supply!

Pocket lights and stick lights are portable auxiliary lights, which are very convenient for indoor atmosphere adjustment or outdoor lighting, but they need to be used at close range because of their low power and limited brightness.

Pay attention to the following points when choosing:

1, power

The mainstream normally-lit fill lamps have powers of 100W, 150W, 200W and 300W. If it is an indoor scene fill lamp, it is necessary to choose fill lamps above 150 W ... and add 150W as needed. Specific facial details and environment rendering can be achieved by considering bar light and panel light.

If it is a private live broadcast or self-media video shooting, you don't need to show the products, just enhance the facial color of the characters to look more beautiful, and it doesn't cost too much. Generally, you can use a fill light with an adjustable color temperature of 100W to illuminate people around, and then use a stick light, a panel light, a pocket light, etc. In order to highlight the facial color, even just put a pocket lamp and a panel lamp in front of the computer to adjust the atmosphere, mainly depending on personal needs.

2. Color temperature

Color temperature is the degree of color presentation of light, as shown in the following figure, different color temperature ranges can make light present different atmosphere. Color temperature is mainly used to contrast the atmosphere, including people and scenes. By adjusting the color temperature, colors can be changed to present different scenes and feelings.

At present, the fill light is divided into three forms: single color temperature, double color temperature and full color. Single color temperature is not adjustable, and the general parameter is 5600 200 K, while double color temperature can be adjusted cold and warm, generally between 2700 K and 6500 K 200 K. Full color has a wider adjustment range, generally between 2800 K-1000 K 200 K. Generally, the larger the color temperature range, the more scene atmosphere can be presented.

Step 3 be smart

When it comes to brightness, many people will think that brightness refers to the power of the lamp. The higher the power, the brighter the headlights. Anyone who has used LED lamps, energy-saving lamps and incandescent lamps will understand that the years of the three-lamp area with the same power are obviously different. LED lights are the brightest, followed by energy-saving lamps and incandescent lamps.

The brightness of the lamp is mainly determined by the luminous flux, that is, the sum of the light emitted by the lamp in unit time. The greater the value, the greater the brightness. His unit is usually expressed in lumens (lm). The greater the lumen value, the brighter the lamp at the same power. However, at present, many brands will not clearly indicate the specific lumen value parameters.

4. Color index

Color index refers to color rendering index (CRI) and television illumination consistency index (TLCI) respectively. Color rendering index refers to the inherent color reduction degree of light to objects and people, which makes the photographed things brighter and more realistic, just like in the sun. The color rendering index of sunlight is 100, and the closer the light is to 100, the smaller the color distortion of the irradiated object will be. The consistency index of TV lighting is based on the picture output by the camera, which is used to describe the color expression ability of lighting. The higher the index, the better the color performance of the light, and the more atmospheric the shooting. Generally, these two indicators need to reach more than 95%.

5. Brand and model

The best fill light lamps are made in Switzerland and Germany, and the prices abroad are very high. If you pursue cost performance, choose domestic brands. At present, domestic brands are more professional, such as Speedmap, Shenniu and love figure. Among them, Speedmap has the highest cost performance due to the integration of R&D, production and sales, but its brand awareness is slightly lower.
