How to choose a photographic lamp

How to choose a photographic lamp? If photography means writing with light, then the lighting device is the photographer's pen. We often say that photography is the art of using light, and light is essential for any photo. Here's how to choose a photographic lamp and related information.

How to choose photographic lamp 1 1 and led fill light?

At present, led is used as the light source of normally lit lamp, which has the characteristics of small volume, low cost, high strength and low energy consumption, and the failure rate of led is low, and the life of each LED particle is about tens of thousands of hours. It is suggested to choose patch LED. The more LEDs, the greater the brightness and power.

Considering different usage scenarios, it is suggested to choose an adjustable dual color temperature between 3000 K and 6000 K, for example, the color temperature of 5400k which is close to natural light is needed for product picture shooting.

2. Color temperature

Color temperature is an index that needs to be understood when buying photographic lamps. Considering different usage scenarios, it is suggested to choose a dual color temperature that can be adjusted between 2500 K and 6500 K, for example, the color temperature of 5400k that is close to natural light is needed for product picture shooting. The color temperature change of photographic lamp can make shooting more interesting and creative.

3. Color rendering index

CRI index reflects the color rendering of light source and determines whether the light source can more truly restore the essential color of an object. It is recommended to select the display index ≥95. The higher the color rendering index, the better the shooting effect.

4. Other parameters

Power supply parameters: dual power supply mode, conditional direct lithium battery/adapter.

Heat dissipation performance: high temperature is a common problem when LED lamps work, and untimely heat dissipation will greatly reduce the service life of LED lamps.

Remote control: this function is optional, and it is also important that the operation panel is concise and clear.

Compatibility: Good constant light has 1/4 "universal hot shoe socket design, which can be used for cameras, camcorders, tripods, etc.

Whether it's a daily selfie, a snapshot of interesting moments in life, or a professional product shooting, a photographic lamp can be said to be an indispensable equipment if you want to shoot well.

Finally, when choosing a constantly lit photographic lamp, we should adhere to the principle of one point and one price, and try to choose brand equipment. If the production enterprise has no formal qualification, there will be certain security risks.

How to choose photographic lamp 2? First, let's talk about the flash.

When we press the shutter, the flash gives off a strong light. We usually control the light through a flash panel or flash device.

A good flash can have a higher synchronization speed, and with our continuous shooting, it has a faster callback ability.

If you want to improve the image quality, the flash can be said to be the cheapest accessory compared to upgrading the camera and lens.

Let's talk about Chang Guang again.

As the name implies, constant light is a photographic lamp that is always on, such as the light source used in the studio, which generally has the function of adjusting color temperature and dyeing mode. Generally speaking, LED lamp beads are used, and the brightness is stable.

If we only need a large area of light to fill the face when shooting video, then we can choose constant light.

If you want to control the light more, you can choose flash, and there are rich accessories to support our creation.

Generally speaking, the brightness of flash is higher than normal light, and its life is also higher than normal light. For users who only take pictures, it can be said that it is the most cost-effective choice.

How to choose photographic lamp 3? Advantages and the difference between continuous lighting;

1, flash point: It has a built-in low-power modeling light, which is always on to let you know where the flash from the strong point will hit. Modeling lights are also useful in dim studios, because the camera's focusing system needs enough light.

2. Continuous lighting: a light source that is always on. For beginners, continuous light is usually easier to use because you can see the light in real time instead of adjusting it all the time (however, some strong points do use continuous mode when setting the light position).

Tips: When shooting still life, it is good to use continuous lighting, but for moving objects or people, it is recommended to use strongpoint, because strongpoint can almost automatically freeze.

Use one lamp or more lamps?

Many people start with a lot of lights, but, to be honest, this is usually a field where less is more. Start with only one lamp. When you are satisfied with the quality and position of the light, if you think it is necessary to add a second light (perhaps a hairstyle light or a background light), turn off the first light, adjust the second light, and then turn on the first light until you achieve the desired effect. When doing this, don't forget the effect of the first lamp (remember, beautiful window light often comes from a window). Therefore, when lighting, only one lamp is turned on at a time, which will get better results.

Soft box, the bigger the better.

The bigger the soft box, the softer the light and the better the packaging of the light, which will make it much easier to illuminate multiple objects at the same time.

The more advantages, the better.

Ninety-nine percent of the time, we only use studio strongpoint's 1/4 or lower power. This is because we always put the light near the subject (the closer the soft light box is to the subject, the softer and more beautiful the light is). If we turn on the light a little brighter, it will be too bright. Many times, we let the lamp work at the lowest power setting, and rarely have the opportunity to use the maximum power provided by strongpoint.

Spend more money on decorative accessories than lamps.

Suggestions like "spend more money on lenses instead of cameras" also apply to flashlights. All flashlights give off bright flashes when they are turned on. Expensive, cheap, studio glare and hot shoe flashlights are basically used to produce bright flashes. Therefore, spend more money on decorative accessories-soft boxes and accessories for adjusting and decorating light-instead of "bright flashlights" to make machines.

All kinds of lighting equipment and decorative accessories commonly used in the studio.

1, main light-main light-highlights the brightest part of the subject, which is the most important light source in photography.

2. Auxiliary light-supplementary light-auxiliary light source, which is used to supplement the light in the dark part of the theme and adjust the light ratio when controlling the light ratio.

3. One of background light-background light-effect light, brighten the background area, otherwise the theme and background will lack light field and layering, resulting in background shadow.

4. Lighting is one of the effect light, which separates the hair from the dark background. Not applicable only when the background is bright.

5, spotlight effect light-background light theme light-making strong light effects, if you insert a special shape insert, you can get different shapes of light and shadow effects, often used to make background light and shadow.

6. Other effect lights-effect lights-other effect lights, such as "background light", highlight the outline of the theme. The skills and functions used depend on the photographer's needs.

In lighting, in order to improve the light quality and color of each light, such as changing direct light into scattered light or condensed light, we can use auxiliary equipment of lighting, such as reflective umbrella, shadowless cover, four-leaf shutter and other equipment to change different light quality. Its key equipment and functions are as follows

(1) Reflective umbrella: The reflective umbrella is installed in front of the lamp, and the naked light (light without any shielding) is converted into jumping light (light with reflector) by using the anti-knock function of this umbrella. This form of lighting method makes the light quality become the property of scattered light, thus obtaining softer light quality. Usually installed on auxiliary lights or main lights. Its material is silver or white, but white is more commonly used and the light quality is softer.

(2) Shadowless hood: Shadowless hood is the simplest and most direct scattering light conversion device. Its function is to make a translucent white cloth into a lampshade and cover it directly on the lamp holder. The direct light will diffuse into the light quality of scattered light after passing through this cloth cover, and the operation is simple and convenient. It is the most important and widely used equipment to change the light quality in the studio.

Commonly used for main lights or auxiliary lights, the sizes are large and small, and can be purchased according to the photographer's shooting purpose.

(3) Sharp nose mask: It is a device with the opposite function to shadowless mask. When the funnel-shaped cylinder similar to the pig's mouth is installed in front of the lamp holder, it will guide the light of the naked lamp to the light projection place more intensively, forming a spotlight state, and it is the most commonly used light guide device for lighting and spotlight effect.

(4) Four-leaf light shield: This is a multifunctional equipment. Its shape is a cover composed of four movable shutters, which can get a large or small range of illumination according to the size and aperture of the blade. It is the best creative equipment to change the illumination range. You can also use its jack to insert any color film to get color light with changed colors. Easy to operate, it is an important multifunctional device, which is often used to change the background light.

(5) Color film and other accessories: Color film is a kind of color transparent film that can change the color of light. It is made of plastic, and photographers can change it according to their own preferences. In addition, there are dimming materials such as tracing paper. You can refer to the instructions of various material manufacturers and make full use of the photographer's photography content to achieve different lighting design effects.

Understand these basic knowledge and choose the appropriate photographic lighting equipment according to your actual needs.
