Lighting photography skills

In the lighting of portrait photography, different lighting methods can create various atmosphere effects. What I want to share with you is the lighting photography skills. I hope you will like it!

Lighting photography skills

1. Soft light

A: Soft light.

This is the simplest light distribution method, and it is also the most commonly used one for myself. It just needs a soft lamp. Just put it on the left and right sides of the model. The soft light should be placed a little higher than the model and photographed at a 45-degree angle from above.

put strees on the key point

A: soft light, b: reflector

If you think it's too dark to use only one soft light, you can put a reflector opposite the main light. Refracting part of the light makes the details that need to be highlighted clearer and highlights the whole subject.

3. Strengthen the contrast

A: soft light, b: black reflector

The purpose of using a reflector is to increase brightness, while using a black reflector is the opposite. Technically speaking, its function is not to reflect light, so you can also call it a "dimming board" or a "light absorption board". The reason why the black reflector is used is to reduce the brightness of the subject side and make the contrast effect of the photo more prominent.

4. Backlight type

A: soft light, b: backlight

If you want to add a little different effect to the photo, you can highlight the layers of the model's hair with backlight, and highlight the model's figure.

5. Indirect explanation

A: soft light, b: side light

The intensity of soft light is higher than that of side light, which can fill the front of the model and reduce the contrast between light and dark.

6. Three Lamps District

A: soft light, b: colored side light, c: colored side light.

Adding two different colors of lights behind the model can make a special effect for the photo, which is very suitable for shooting fashion.

Practical photographic lighting skills

Observation light source

Lighting sources in real life can be roughly divided into two categories: natural light and human light. The representative of natural light is sunlight. There are tungsten lamp, fluorescent lamps and mercury lamps on the artificial light highway.

In the field of film and television lighting, it is necessary to define and set the "light source" environment of film and television scenes. Especially in the case of artificial light source, is it tungsten lamp or fluorescent lamp? Different settings create a completely different atmosphere.

Let's take a look at this scene (below 1.2). There are three roads in the foreground, blue on both sides and yellow in the middle. Choose this place to shoot, if the light source is uncertain, and the shot is shot from shot to shot, the connection will be chaotic and there will be light jumping.

colour temperature

Color temperature is an expression of "colored light".

The most popular explanation is that the color temperature is "the color of light". The low color temperature is red and the high color temperature is blue.

The most popular explanation is that the color temperature is "the color of light". The low color temperature is red and the high color temperature is blue.

The light in life has the characteristic of color deviation, which is called "colored light", but people have developed the habit of treating "colored light" as "colorless light". No one can see "colored light". Even if you wear colored glasses, once you wear them for a long time, you will feel no color after adapting, and you will still "feel normal" about the light and shadow of this world.

We need a stable "color light" when making a movie, otherwise we can't enjoy the image because it is red and blue for a while. Generally, we choose stable "color light", including high color temperature light source 5500k and low color temperature light source 3200k K, so the manufacturers of light bulbs made two kinds of light bulbs for filming. With the popularization of image culture, high color temperature light source 5500k and low color temperature light source 3200k, as two standards, have gradually become common sense in film and television, and this "common sense" can be used to play "light color" and add color to images.

High color temperature light source 5500k

In the case of direct sunlight, the color temperature is about 5500k K, which is called "sunlight", and the so-called "direct sunlight" is the color temperature when the sun is direct. In cloudy weather, when sunlight passes through the clouds, the color temperature will reach above 6000 K.

Low color temperature light source 3200k

The basic color temperature of light source in tungsten lamp is 3200k, but the bulb will age after long-term use, and its color temperature will decrease.

The light source in real life is very subtle. Fluorescent lamps can be divided into white and daytime colors. In film and television production, those professional fluorescent lamps use the number of A to evaluate cathode fluorescent lamps, and AAA stands for high grade, which is called 3A cathode fluorescent lamps. Its color temperature is relatively good, about 4500-4800, and these color temperature values will change due to factors such as lamp life and cleanliness.

The concept of normal light source

The concept of "normal light source" in photography refers to a light source that can correctly restore the color of an object by correcting "colored light". For example, a digital camera can automatically correct "colored light" to "colorless light" after automatic white balance setting.

Play with color temperature (white balance)

In digital photography, the characteristics of color temperature can be used to reproduce a specific light source, which is the technology of color temperature application. Specifically, when adjusting the white balance, use warm white paper as the "white label" to shoot, and the camera will be biased towards cool color. Similarly, using blue and white paper as the "white label" and adjusting the "white balance", the camera will be biased towards warm colors. You can also adjust the color of the picture by computer in the later stage of production.

If you want to reproduce the taste of moonlight, you can rely on lighting to express it. The color temperature of the light is higher than the "white reference" of the camera 1000-2000K, and the color will be blue. The picture has a blue hue, which can clearly express the atmosphere at night.

If you want to reproduce the orange feeling of Edison's light bulb, such as the lighting in restaurants, bars and other places, you can reduce the color temperature of "white reference" by about 500k K, and if the scene is set as a commodity exhibition hall, you should also reduce the color temperature. In fact, many high-end stores install dimming devices to reduce the color temperature of the lights that illuminate goods to attract customers' attention. Experts believe that it is best to use orange light as a memory color to display goods.

The original intention of spreading light

Lighting is to ensure the necessary light.

You can't shoot at will in poor light. Lighting can improve the brightness of the environment and ensure the necessary sensitivity.

Polishing is to promote bright colors.

The color of the image is closely related to the sufficient illumination when shooting. If there is insufficient light, you can't expect full colors. If there is no basic lighting in the dark, the captured image will be eclipsed.

Lighting is visual creativity.

The director's idea of light effect is a kind of scene scheduling, called "visual induction", and the arrangement of light is indispensable. Lighting can change what is photographed, so that the audience's impression of existing life is determined by lighting.
