What are the differences between shooting xenon lamps, tungsten wires, fluorescent lights and LEDs? How to choose when using them?
Nowadays, the lighting tools on the market are not a wide variety of prices, which makes it difficult for people to choose which one to use. Understanding the role of lighting tools can help us choose the lighting equipment we need. The following topics include different types of lighting tools, the scope of use of different tools, and the reasons for choosing a lighting tool. HMI 1. What is HMI? The HMI lamp (Hydrargyrum medium-arc iodide) is a standard for movies and TV shows. HMI lamps are available in sizes ranging from 200 watts to 24,000 watts. They need to be operated under the weight of gravity, and some low-wattage lamps can be used at home or office power, but most require generators or high-current circuits to work properly. It should be noted that the HMI lamp is very expensive. 2. Use category In general, HMI lamps are used to produce daylight or daylight because its standard color temperature is 5600K~6000K. HMI lamps produce a large amount of light, producing four times more light per watt than a typical tungsten filament. Most of the moonlight and daylight scenes we see in movies use HMI lights. 3. Reasons for choosing HMI HMI has a lot of features, and it will be used when the scenes that require lighting are large. Of course, it can also be used to simulate moonlight or daylight, and the effect is very good. Tungsten lamp 1. What is a tungsten lamp Since the film's inception, tungsten lamps (or Halogen) have been used, relying on incandescent bulbs, and the use of incandescent lamps dates back to the late 19th century. The color temperature of the tungsten lamp is between 3200k and 3800k, which can be used on household electricity. Large point power lamps require operation under generator or high current circuitry. There are also many types of tungsten lamps, and they are cheap. 2. Use category Tungsten filament lamps can be used in a wide range of applications, from special lighting to large amounts of lighting, to stage and theater. Like the HMI, the tungsten light can also be used in lighting fixtures and large scenes. Although it does not have the light generated by the HMI, it has its own characteristics. For example, in high-speed shooting, it will suppress the HMI because he will not have a strobe. 3. Reasons for choosing tungsten lamps Tungsten lamps are often used for special lighting such as backlights, contour lights and effect lights. Although the HMI has a flash-proof stabilizer, until today, most people use tungsten lamps when shooting at high speeds (generally above 300fps). Florescent 1. What is fluorescent lamp Fluorescent bulbs are used for fluorescent lamps. The principle of illumination is that the steam caused by the omission of electricity is heated in the lamp. This kind of lamp is common in office buildings, and now there are many households. In movies or videos, we use it as a soft light, which produces relatively low temperatures, correspondingly consumes less power and is less expensive. A typical example is KINOFLO. 2. How to use Fluorescent lamps are often used in the lighting of shooting scenes, often to restore shooting scenes, such as offices and industrial locations. It can also be used for shooting from medium to close shots. The downside of Florescent is that the intensity of the light produced is not large, and the distance of illumination is not very far, so it is generally not used to illuminate large scenes, nor is it used for outdoor lighting. 3. Reasons for using fluorescent lamps General shooting interviews or fluorescent lamps in dense areas, digital cameras can now shoot with low noise at high sensitivity, sometimes the amount of light is small and does not affect anything. At the same time, the light from the fluorescent lamp is very gentle, which does not require the use of a soft lens. Fluorescent lamps are typically used with dimmers, which makes them flexible when used as auxiliary light. led 1. What is LED? The light of the LED (Light-Emitting Diode) is very strong, and it is higher than the color temperature of the lamp mentioned above. LEDs were previously used as infrared light, and were used for visible light in electronic appliances in the 20th and 60s. LEDs are now used in film and television shooting, and sometimes as a light source. Some LEDs can change the color temperature with a simple adjustment, which makes it more widely used in film and video recording. Like fluorescent lamps, LEDs are not too expensive, and with the added flexibility, they are worth buying. 2. Scope of use There are many products that use LEDs, such as light sources, auxiliary lights, lighting equipment, green screens or keying, special effects lighting and live broadcast lights. From radio to wedding photography, as well as music videos, short films and feature films, documentaries and promos, LEDs are ubiquitous. However, the amount of light in LEDs is not very high, so it is generally not used in exterior scenes and large scenes. 3. Reasons for choosing LED In recent years, manufacturers have begun to change the way they use LEDs, and believe that their use will become wider and wider. Although the illumination of the LED is not very wide, it can not meet the requirements of outdoor lighting, but in the theme of lighting, background, narrow space lighting, its effect is still very good. The more modern the lamp, the better it will do in terms of light diffusion. Such lighting will be soft and in line with the aesthetics of fluorescent lamps.
