What is a studio flash?

Introduction: Studio flash is the light source needed for shooting in the studio. So what is a film and television flash? Come with me to find out! What is a studio flash

Studio flash strobe flash, also known as flash, studio light. Studio flash is an artificial light source used in photography studios. Studio flash uses high-voltage and large current to discharge through a xenon lamp instantaneously (from 1/800 second to 1/2000 second) to emit a strong flash. The power consumption is very low and the light intensity is very high. Working principle of studio flash

Capacitor:

Capacitors are generally divided into two types, one is a boost capacitor, also called a negative capacitor, and the other is a main capacitor for energy storage. The size of the main capacitor directly determines the energy that the flash tube can release. Generally speaking, a 400W/S lamp requires about four main capacitors of more than 400UF. Flash tubes convert energy directly into strong light. The lamps not only require a high number of flashes and high flash intensity, but also have very precise requirements on color temperature. Most flash tubes are around 5600k. In order to correct the color, many big foreign brands will use their own customized flash tubes, coated with different films to adjust the color temperature. For example, Brown's flash tube looks a bit light blue.

There are mainly four types of capacitors on the market. The best in the first category is the German capacitor (Kangsu). The second category is Japanese capacitors, mainly Rubycon (domestically called ruby) capacitors. I heard that some people also use Japanese black diamond capacitors. In addition, Gaoming Comet uses Sanyo capacitors, but rubycon is specialized in making flash capacitors, so ruby ??capacitors are used. It is still more suitable for flash, and most flash manufacturers also prefer ruby. Most foreign brands use ruby ??capacitors, such as Elinchrom, ACE, Baorong, etc. Most manufacturers' high-end products also use ruby ??capacitors. The third category is domestic capacitors, generally HEC capacitors are visible. The fourth category is fake capacitors, mainly ruby ??capacitors of unknown origin. A certain brand has been widely used. The first determinant of capacitance is the discharge power. The larger the capacitor, the greater the power and the higher the price. In addition, the better the capacitor, the more fully it is discharged each time, and the greater the actual power it displays. The second is the recycle time. A good capacitor recycles quickly.

Lamp:

There are three factors that directly determine the lamp. One is the number of flashes, the second is the flash intensity, and the third is the color temperature.

In terms of the number of flashes, Haiman lamps come in various levels, with lifespans up to 100,000 flashes. The lowest-end ones generally have a lifespan of 3w times, and are also commonly used in domestic lamps.

Color temperature:

Generally it should be between 5500-5600. In order to calibrate the color temperature, foreign brands usually customize specially coated lamp tubes from Haiman.

Circuit board design:

Generally, foreign manufacturers have decades of experience in circuit board design. The average domestic manufacturer has only started less than 6 years ago, and the stability of circuit boards needs to be improved.
