Beam light tube to reduce the light irradiation area for local lighting, the feature is to focus the light into a bundle, often used to highlight the side of the local light beam tube is hitting hard light, the characteristics of the honeycomb to follow the transmission of wood Of the light, light area is small, the intensity of irradiation, the level is very rich, light ratio, the use of beam light tube "hive" role is to let the light appear layered, more tough three-dimensional, shooting fashion personality male and female students more obvious effect .
As the name suggests, is the difference between a light and two lights, the former is bright, the latter is more bright, relatively speaking, dual lights not only provide a brighter effect but also broaden the camera in dark light conditions better viewing angle range. Essential function is not much difference.
Photographic light flash can be used with a flashlight link camera can achieve the effect of flash, instantaneous power, high intensity. Camera lights need to be lit in the photography process, so the power is generally lower than the photographic lights. Suggestions or according to their own frequency of use to choose, so as to avoid waste.
Good quality outside the flash and flash lights have no difference between good and bad, outside the light output much larger. SLR with the so-called high-speed synchronization lights are some problems, really want to use a higher shutter speed have to rely on a higher synchronization speed using the mirror between the camera shutter. In the indoor use of good outside light if the output is relatively low, in fact, it can be very good solidification of high-speed moving objects, and the camera's shutter speed is not much relationship. Light soft or hard does not exist good or bad points, look at your shooting needs, using different accessories to get different light quality.
1, a small studio to buy a small lamp power: shooting 5 ping below the ceiling height below 3 m 1, the best buy about 200 watt lamps, not more than 400 watts.
2. Large studios to buy the power of light: shooting more than 5 ping space, the ceiling height of 3 meters 1 or more, it is best to buy 400 & sim; 600 watts lamps.
3. External flash light output is no less than the studio lamp, but due to the slow callback and easy to hot, shooting mode must be considered; if often continuous shooting, it is advisable to buy shed light.
4. Shade lights have extra lights, single lights and barrels, it is recommended that the average person by the outside light and light a single lamp is appropriate to start, if you want to shoot at high speed, the barrel is more suitable.
5, some of the photography lights are special, not universal, and some photographic lights are driven by * strong battery, so buy a photographic lamp have to consider the existing battery capacity, if necessary, may require additional purchase.
* Note: Photographic light as a more important photographic equipment, the real use of photography enthusiasts are still a minority, many of my friends do not know how to improve the shooting quality of the dark environment, or complain about the lack of performance of digital When you really want to make the hands of the digital video camera to play a practical value, the acquisition of a photographic lamp, is very necessary.
Before we introduce the role of photographic uplights and the use of technology, give everyone a new generation of photographic fill light advantages and characteristics. In fact, photography fill light, also known as camera lights, headlights, news lights and so on! Nowadays the photographic fill light on the market is commonly used LED light-emitting diodes for light, this material LED photographic fill light fill has high efficiency, low voltage, small size, long life, fast response, strong seismic capacity, Energy saving, environmental protection and other characteristics. At present, people said the fill light usually have three kinds, one is the camera greenhouse fill light (also called plant fill light), photographic fill light (also known as photographic light or camera fill light), license plate fill light Also called white light).
The built-in flash might be enough for average beginners, but the external flash is a must-have for professional photographers and some well-established photographers, especially in the room or in the light In case of insufficient use more.
When you have an external flash, you will find the photo clarity will be higher, especially in portrait photography, even if the ambient light is sufficient, the use of external flash will become more clear. If you are using natural light shooting, the skin is easy to have a sense of plastic, and use the flash can make up for this defect, of course, the effect is leveraged.
Light is an important means of completing photographic techniques so as to realize the artistic style of the picture. Without light, there is no image of things. So light is an essential element. Especially architectural photography and indoor photography. Whether you are shooting a large hotel view, the interior of a typical home, or the interior of a large building, the light determines the texture of the picture and the atmosphere created by the entire space. Only learned how to use the light, then you have the value of photography.
Usually professional photographers will be flexible use of light to emphasize the characteristics of the shooting space. Because it can arouse the interest of onlookers, so that the screen produces a level and three-dimensional sense of people feel enough room light, but also to define the space, a clear picture of the texture and color. Although natural light is beautiful, we can not always grasp the light of nature, especially in indoor photography. At this moment, we do not sincerely think of auxiliary light, and if we can adjust the auxiliary light flexibly, we can shoot high-quality indoor photography works.
Here is a introduction to the introduction of indoor lighting equipment introduction:
1. External top flash system, usually traveling, usually with a total power of 25000W (about 7 power box and 12 flash head) power box, almost all use. My lighting equipment is more complicated, but it is not necessary to achieve the ideal lighting effect, and the simple equipment can achieve better results.
The advantages of a photoflash flash head color temperature: Conversion from daylight color temperature to other color temperatures such as tungsten or fluorescent lamps; Controlling shutter speed: If the indoor daylight is strong or you want to take an outdoor view through the window, Ratio is very important; if you only have a lighting equipment, I strongly recommend that you use 4-6 high-power flash head and provide them with sufficient 1200W / S power.
2. Auxiliary flash equipment, professional studio lighting: If the original light source is a tungsten lamp, I will use the ordinary long bright white light. These rays are neither very convergent nor very diffuse. The color temperature is about 3200K, so a slight correction of the color is required. Otherwise, it will be colder than the place where the tungsten light shines on the screen.
Generally in the shooting of high-quality buildings and indoor photography, ultimately, the addition of light, the importance of lighting for photography is far more important than the composition. The usual use of light, including color balance, shows the texture and color of the object perfectly, creating a vivid effect that is impossible with natural light alone.
* Tips: If you are just a photography enthusiast, it is not necessary to spend more money on too many photographic equipment, there are certain equipment can be.
The role of the radome is to shoot a very hard light strong light, to a certain height of the light, the aperture can be used to shoot a small, showing the details of the characteristics and strong texture. Radome as the largest reflector, of course, can be used with the hive, the exchange can be used for the main light and modified light. The light source area is smaller than the softbox, the irradiation intensity is bigger than the softbox, the level is very rich, the light ratio is bigger, the function of the "honeycomb and the radome" is to let the light appear the layered feeling, harder and harder to shoot the fashionable personality Male and female students when the effect is more obvious.
1, the power supply is not normal caused the problem:
01. Check the power supply is not working properly, the indicator light is not lit, if not lit up, please check the power is not connected;
02. Check whether the power cord of the lamp is connected with the positive and negative poles of the power supply. Is there any reverse phase? If the above problems exist, please connect correctly.
2, LED lamp beads for the voltage requirements:
Nominal 3V LED lamp beads, in fact, different colors of the current also have different requirements, the minimum requirement of yellow current, followed by red, green, white and blue. The current is too large, will make the wick burnt. But the current is too large, will still be burned.
3, how braided LED lamp beads luminous color:
In the case of no power supply, if in order to choose the convenience of the purchase, it is recommended to prepare a 3V button battery, when used in the selection of the battery can easily check the LED light.
4, high-power led lamp beads burn reason:
01, up and down the two filaments, the industry called gold line, pure gold, do conductive use, two positive, two negative, the real good product there will be the fifth line, welding Zener tube, and protection effect.
02, the shorter filament shows that the lamp has been burned by a large current, the equivalent of a broken line
03, high-power 1W drive current around 350ma, the working voltage between 3.2-3.6V, please be sure to pay attention to the use of excessive current will burn the light
04, the general three 1W aluminum lamp are about 12V drive, very few directly on the use of 220V in use must have a constant current source
5, LED lamp beads yellow reason:
LED encapsulant yellow mostly due to epoxy resin and curing agent does not match due, but also can not rule out the outer plastic sealing time is too long.
6, LED lamp bead leakage reasons:
Machine equipment is not grounded, the staff did not wear electrostatic wristbands (must be corded). Caused by improper electrostatic protection. Then there is the packaging process, welding PAD welding bias, the last is the quality of the chip itself hidden problems.
7, LED lamp beads should be capacity, the problem of inductive load:
Neither, LED lamp beads is a diode, you need to be able to work a positive on-voltage, usually 2-3.5V, in addition, the current size can control the brightness of LED lamp beads. LED lamp beads just electric energy into light energy.
8, with LED lights pearl big reason:
01: Iron bracket poor thermal conductivity.
02: Epoxy yellowing.
03: chip and bracket contact is not close enough.
04: chip attenuation big.
05: If it is white, there is phosphor decay problem.
LED video light is now widely used in wedding photography, news coverage, filming, studio lighting, flat still photography and other fields, many television studios are one after another will be the traditional power consumption, noise, bulky , The heat of the photographic light replaced by LED photography light. More and more still-life photographers have also begun to use LED photography light to complete the jewelry shooting.
Professional LED photography light price is too expensive in the broadcasting industry has become a consensus. The final conclusion of the comprehensive cost report made by foreign countries for lighting products is "yuan / hour." Taking the energy-saving lamps and tungsten lamps for calculation, the cost of electricity is several times worse, so the purchase cost and life expectancy are combined , Energy-saving lamps per hour costs much lower.
LED light is the same calculation method, with the same brightness and the same battery life, the cost of electricity about 7 times the difference (the proportion of the overall small proportion), the weight of LED photography light, light, more portable . Good LED video light with excellent bulbs, therefore, the overall life expectancy is longer, only the life of this piece of calculation, LED camera light hours cost much lower.
