How to make good lighting for photography?

The traditional lighting is that the main light is 45 degrees away from the front of the main body, the auxiliary light is 75 degrees, and the head is illuminated. The main light is used to depict people's image and expression, the auxiliary light plays down the shadow of the main light to enrich the level, and the light separates people from the background to enhance the three-dimensional sense. Because this lighting method has been used in China for a long time to take all the portraits, it is called traditional lighting. Triangular light (also known as V-shaped light) is the most commonly used trend lighting form in photo studios in recent years. This kind of lamp is developed from the eight-character lamp. In the past, wedding photos and plane art photos were all illuminated by eight-character light, that is, two beams of light shone on the subject at the same distance at a 45-degree angle, and the brightness was completely equal. The light ratio is usually 1: 1. The 90-degree light zone consists of 45-degree double lamps, which is called double lamp balance for short. When the angle exceeds 90 degrees or is less than 90 degrees, the angle changes, and the light receiving surface also changes, so it is not a figure of eight light. If Yi Deng is in the front and Yi Deng is in the back, it will be even worse. There are big eight-character light and small eight-character light, which are mainly plane light with bright and bright characteristics. Warm, once recognized by portrait photographers as the most beautiful and beautiful light source. But this kind of lamp is used too much, and everyone always feels ugly and lacks personality. Later, some photographers introduced advertising photography into wedding portrait photography. On the premise of the original eight-character lamp, a lamp is added to the ground, which is also plane lighting. It is found that the eyes of the characters are particularly bright, crystal clear and impactful, which eliminates the shadow between two people. The shadow on the neck disappears, making the film look cleaner and brighter, and the eyes are more prominent. This is triangular lighting. However, some people think that people with this kind of light are fatter, because they have not mastered its skills and methods. 1. Triangular light belongs to the category of large plane light in character modeling. It consists of three soft lights, two of which are located on the left and right sides of the camera. Place a soft light in front of the subject, and the subject is in the triangular light area, which is called triangular light for short. 2. Position of the light: aim the center of the light's flexible frame (that is, the center of the light source) at the hair position of the subject, with the lower part of the flexible frame facing the subject's face and the upper part facing the background behind the subject, because the center of the light emitted by the flexible frame is the brightest and the four sides will be dark. Generally, the aperture between the center and the edge is 0.8 to 1. Therefore, the brightest light source illuminates the hair, which is transparent and layered because it absorbs light and increases exposure. The face is highly reflective, which can balance the light of face and hair with a relatively weak light source, and the upper part of the soft light box shines on the background to enhance the level and brightness of the background. In general, triangle lights don't need to emit lights. In order to make the picture more natural and realistic. When the position of one lamp is fixed, the other lamp illuminates the subject at the same height from the other side. The application of floor lamp should not be too bright or too dark. Too bright will make the contours of the face and neck disappear, too dark will lose the meaning of triangular light, and will not give people a transparent and bright feeling. Therefore, the intensity of the three light areas is the same. The distance between the lamp and the main body is the same. 3. Before using triangle lamps, it is necessary to measure the intensity of each lamp with a sidelight instrument, just to measure the aperture value of the main body illuminated by the lamp. In the process of shooting, the distance is shortened, the corresponding aperture is reduced, the distance is increased, and the aperture is raised. In this way, there is little chance of light error when shooting.
