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. The following is 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 bright lamps, 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 a dual color temperature that can be adjusted between 3000 K and 6000 K, for example, the color temperature of 5400k that is close to natural light is needed for product picture shooting.
2. Color temperature
Color temperature is an index that you need to know 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 the light source, which determines whether the light source can more truly restore the essential color of the 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, with 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 always-on lamps have 1/4 inch 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 shoot, a photographic lamp can be said to be an indispensable equipment if you want to shoot well.
Finally, when you choose a constantly-lit photographic lamp, you should stick to the principle of one point for one price, and choose brand equipment as much as possible. 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 flash panels or flash devices.
A good flash can have a higher synchronization speed, and cooperate with our continuous shooting to have a faster callback ability.
If we want to improve the picture quality, the flash can be said to be the cheapest accessory compared with upgrading the camera and lens.
Let's talk about Chang Liang again
As the name implies, a constant light is a photographic light 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, using LED lamp beads, the brightness is stable.
If we only need some large-area lighting to fill the face to shoot video, then we can choose constant light.
If we want to control the light more, we can choose the flash, which has rich accessories to support our creation.
Generally speaking, the brightness of the flash is higher than the constant brightness, and its life is also higher than the constant brightness. For users who only take pictures, it can be said that it is the most cost-effective choice.
How to choose photographic lamp 3? The difference between strong point lighting and continuous lighting;
1, flash strong 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 shine. 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 very effective to use continuous lighting, but for moving objects or people, it is recommended to use strongpoint, because strongpoint can freeze almost automatically.
Use one lamp or more lamps?
Many people use a lot of lights from the beginning, but, to be honest, this is usually a field where less is more. Start with a 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 and adjust the second light first, and then turn on the first light until the desired effect is achieved. When doing this, don't forget the effect of the first lamp (remember, beautiful window light often comes from the window). Therefore, only turn on one lamp at a time when lighting, which will get better results.
The bigger the soft box, the better.
The bigger the soft box, the softer the light and the better the light packaging, 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 close to the subject (the closer the soft 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. Most of the time, 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 the lens instead of the camera" also apply to the flash. All flashlights give off bright flashes when they are turned on. Expensive, cheap, studio flashlights and hot boots are basically used to produce bright flashes. Therefore, more money is spent on decorative accessories-soft boxes and accessories for adjusting and decorating light-rather than "bright flashlights" to make machines.
All kinds of lighting equipment and decorative accessories commonly used in the studio.
1, main light-main light-brightens the brightest part of the subject, which is the most important light source in photography.
2. Auxiliary light-fill light-an auxiliary light source used to fill 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, and produce background shadows.
4. Lighting is one of effect light, which separates hair from dark background. It is 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 light-effect light-other effect light, such as "backlight", which highlights 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 changing it into concentrated light, we can use auxiliary equipment of light, 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.
It is often used in main lights or auxiliary lights, and its size is large or small, which 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, which 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 obtain a larger or smaller illumination range according to the size and aperture of the blade. It is the best creative equipment to change the lighting 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. Its material is plastic, and photographers can change it according to their own preferences. In addition, there are tracing paper and other dimming materials. You can refer to the instructions of various material manufacturers and make full use of them to achieve different lighting designs according to the photographer's photography content.
Understand these basic knowledge, and choose the appropriate photographic lighting equipment according to your actual needs.
