Product classification of studio flash

1, synchronous flash bulb (electronic umbrella lamp). The price of lamps is very low. Each lamp is 70 ~ 90 yuan, using 220 V AC power directly, and there is no trigger socket. It can only work in flash synchronous trigger mode. Generally, two or three lamp holders are used with a reflective umbrella. Operators with small investment can choose this kind of lamps in the early stage of opening, and a license can completely cope. Operators should remember to replace a set of higher studio lights immediately after making money, otherwise it will be difficult to improve the level of photography. Many operators who use flash bulbs find that the color and definition of photos are not bright enough, and changing cameras, lenses and films can't solve the problem. At this time, changing the lights is the only way to improve the quality of photos.

2. Universal Studio flash. The energy of the lamp is between150 and 250 watt-seconds. The appearance and usage are not much different from those of professional flashlights, but the internal quality is quite different. First of all, the flash lamp has no voltage stabilizing circuit, and the flash intensity of the flash lamp changes with the change of power supply, which will affect the quality of taking pictures. It is best to add an AC voltage regulator to use this lamp. Secondly, the flash uses a high-voltage trigger circuit, and the trigger voltage is as high as 300 volts. Inadvertent use will lead to numbness. Third, the color temperature and life span of each tube in the flash may vary greatly.

3, professional studio flash. Professional studio flash should be understood not only as its function, but also as its inherent quality and stability. For example, professional lamps are equipped with voltage stabilizing circuit to ensure the stability of color temperature and flash intensity, low-voltage trigger circuit, faster recovery time, lower flash leakage rate and failure rate. This kind of flash lamp adopts high-quality imported flash tube, main capacitor for flash lamp, imported integrated circuit, thyristor and other electronic components. 1. Buy the cheapest: any shopping should consider the cost performance of the goods. For operators, lamps are the means of production, just like cameras, and they are the capital to make money. If the light breaks down for one day, they will lose their income for one day. Smart consumers will not easily buy the cheapest means of production, nor should they believe the unilateral propaganda of manufacturers, but should visit users who have used this brand of lamps.

2. Imported lamps and domestic lamps in Taiwan Province Province are better than ordinary domestic lamps: in addition to ordinary domestic lamps, there are two kinds of studio flashlights, namely European imported lamps and domestic lamps in Taiwan Province Province. Lamps imported from Europe are generally world-famous lamps, such as Brown, Ai Linglong, Invincible Overlord and Garbo. This kind of lamp is advanced in technology, stable in quality but expensive, which is more than twice as expensive as domestic lamps of the same specification. Now remind users to pay attention to the after-sales service of imported lamps. Generally, imported lamps in Europe will have various failures after two or three years of use, and many users have encountered such troubles. Taiwan Province lamps have a certain market in China. Imported high-quality lamps and Japanese main capacitors are used, and the price is about 1/3 higher than that of ordinary domestic lamps. However, the measured indicators of Taiwan Province lamps are quite different from their nominal indicators, and are quite different from the domestic high-quality studio lamps. 1, type and quantity of lamps and lanterns

The choice of lamp type needs to be decided according to the area of the studio and the content to be photographed. The same is true for the selection of lamp fittings. The size of the soft box, the choice of honeycomb cover and beam bucket also depends on the shooting content.

2. Output power

Generally, the flash power of professional photo studios is between 600W and1200 W. Some lamps used for commercial shooting have several thousand W output power, and the photographic lamps for shooting large advertisements can reach tens of thousands W. For photographers and small-scale studios, it is necessary to find a balance between sufficiency and economy. General 150W to 250W flash can meet the needs of simple portrait and landscape photography.

3. The normal color temperature of the color temperature flash is about 5600k, but the color temperature of the flash produced by each manufacturer is different. Even the products of the same brand have individual differences. Using soft light equipment will prolong the service life and reduce the color temperature of the flash. If you buy a set of lamps at the same time, you can measure whether their color temperature is uniform if possible.

4. Call back time

The callback time is related to the continuity of shooting. Generally, the return time of flashlights below 1000W is within 1 to 5 seconds, and the return time of flashlights with higher output power is longer. As long as it is within this range, it is normal, and it is not necessary to ask for too much time to call back. Too short callback will bring great load to the capacitor, and the hidden trouble of fault will also increase. Therefore, even if your flash callback speed is very fast, don't use it continuously and quickly. Many flash instructions will also mention this.

5. Brand selection

There are many brands of studio flash, covering many foreign and domestic brands. Studio flash, a well-known imported brand, has exquisite workmanship, accurate output and stable performance, but its price can be 2 times or even 4 times higher than that of domestic lamps. Therefore, domestic famous brands should be an economic choice for photographers.

Step 6 work

Aluminum alloy shell will be better than plastic shell, one is firm, the other is conducive to heat dissipation, so the failure rate is low. However, in order to reduce the weight, outdoor lights will use more plastic shells. In addition, the circuit board is also a very important reason.

7. After-sales service cannot be ignored.

The working conditions of the flash in the studio are extremely bad. Long-term working under high voltage of 300 volts to 600 volts, the instantaneous current can reach several hundred amperes when flashing. The failure rate is much higher than that of durable appliances such as televisions and refrigerators. Therefore, the life of the photo studio flash is relatively short, and it should belong to consumable appliances. When buying a flashlight in the studio, users should not only consider the price and function, but also consider the "after-sales service" of the manufacturer, mainly from the time when the lamp fails to repair.
