How is light used in photography?

Light is a very important condition in photographic modeling, and shooting with light can make it clearer.

One is the reflection of light by the object, and the other is the color contrast of the object. The light shining on the object makes the object have a difference between light and dark, and its reflection of light makes it a luminous object in itself.

Light can represent the shape of an object. When light hits an object, there is a difference between light and dark on the object. At the same time, the reflection of light from the object essentially becomes a luminous body, thus revealing its position, size, and shape.

Light can also illuminate the details of an object, depicting the details of the object and portraying the verve. Light can also enhance the sense of space. It can also render the atmosphere of the scene and express the texture of the object.

Photography is inseparable from light, there is no fixed way to use light, everything is to serve the theme of the work, and it can be flexibly changed.

<> "Light. The type of light source.

Natural. The common natural light source is the sun, the sun does not use any help, only by burning fuel by itself can achieve the degree of luminescence and heat, this natural light source is more or less physical action, or chemical action to start its own light.

Artificial light. From ancient matches to modern LED lighting, and then to all electronic products that we usually come into contact with, they all belong to the scope of artificial light sources, and the more common ones are lighting sources, because artificial light sources require energy, so they are more expensive than natural light sources.

Ambient light. Ambient light refers to all kinds of light Qicong lines used for lighting in daily life, mostly refers to the interior scene of drama creation or artificial light that appears in life, and can use ambient light to create all kinds of light, such as cloudy, sunny, day, night, dusk, dawn, etc., to set off the subject, highlight the subject, not to make the subject submerged in the background, and also have the effect of creating an environmental atmosphere.

Direction of light: The direction of light is determined by the relative position of the light source, the subject, and the camera. There are five main common light directions: forward light, side light, backlight, side backlight, and top light, and these five types of light have different characteristics.

The same scene will also show different forms under the illumination of light in different directions, and the hall infiltration will also give people a different sense of vision.

The quality of the light.

Bright light. Strong light refers to the dazzling and chaotic light, the light is particularly strong, such as the sun, incandescent lamp, fluorescent lamp shooting at noon will show strong light, we should pay attention to avoid the use of strong light shooting as much as possible in shooting.

Low light. A low-light environment is when the light of the light source in the frame is weak or the shooting lens is far away from the light source. Low light usually occurs at night after the sun goes down or in dimly lit indoor environments.

Hard light. Hard light refers to direct light that is far away, usually irradiated directly on the subject by a light source, such as the midday sun and a flash directly at the subject. Under this kind of light, the illuminated object will produce obvious shadows, the transition between light and dark is direct, the boundary is clear, and the visual experience is relatively "hard".

Soft light. Soft light refers to diffuse light at a close distance, usually not directly from the light source, but is reflected or filtered by non-mirror materials, such as large windows, rising and setting suns, close-up softboxes, etc. Under this type of light, the illuminated object does not produce clear shadows, and the transition between light and dark is gradual and there is no clear dividing line.

Photo schedule.

During this time, the light is soft, and you can use the side backlight backlight to shoot the glowing hair.

During this time, the sun's rays are strong, so it is recommended to shoot indoors to weaken the light through curtains and tulle to form shadows on the body and face, creating a lazy atmosphere in the afternoon.

Excellent time to take pictures, the light is softer, different from the morning light, the light will be warmer, and the appropriate use of reflectors can make ** more transparent, the atmosphere is grasped, and the later sunset can shoot the silhouette of the person.

The way to arrange the light when shooting is to first light the portrait side, and follow the light! The shoulders of the subject should be at an angle of 45 degrees to the optical axis of the lens, not parallel to the optical axis of the lens.

The nose is perpendicular to the optical axis of the lens. When shooting portraits of men, Richard likes to have their chin slightly lowered and their head slightly tilted towards their backs. But the head of the profile portrait of a woman works well no matter which direction it is going - up or down, left or right.

The orientation of the eyes is also important, and it is best to have the pupil of the subject's eye perpendicular to the optical axis of the lens, looking up when the head is slightly tilted, and looking down when the head is down.

Typical applications for front side light are Rembrandt and ring light. In real life, when outdoor activities during the day, the height of the sun is at an angle of about 45 degrees, which is the height of the sun at the main activity moment in life.

Precautions for shooting

Flowers, trees, buildings, etc. have their own colors, so I don't say much here, but you can take pictures when you see them. Mainly introducing, how to shoot the color of the sun. The natural light around sunrise and sunset is colorful. For the most part, the evening is warmer. Early mornings, sometimes warm, sometimes cold.

If you want to shoot landscapes, use a small aperture. The number after the aperture should be as large as 8. Take a silhouette and use spot metering.

If you shoot against the light and want to make the brightness uniform, please use matrix metering (also called evaluation metering). When shooting a landscape horizontally, the horizontal lines in the landscape should be parallel to the top and bottom of the frame. Shoot a vertical wind wheel scene, such as a tree, parallel to the left and right sides of the frame.
