What are the photography skills of shooting the same thing from different angles at a time? Pray for the great gods.

First, the mystery of light Photography is an art of studying light, so how important the four different directions of light are in the application of photography. Light contains all colors and can pass through any transparent object. When it lacks light, it will produce shadows. We don't have to explore the mystery of light, as long as we can make rational use of it. Light is a form of energy, which exists in the universe in the form of electromagnetic waves and is one of many sources of energy. Light energy propagates in the form of waves, and the distance between two peaks is called wavelength. The length of wavelength determines the special form of energy in nature. As shown in the picture below, the light that humans can see is only a short wave band in the picture. We call this light "visible light". Besides, there are invisible lights, and we can only feel their existence in other forms. According to the length of wavelength, we have invented many photometric instruments, which can not only detect infrared rays, but also detect ultraviolet rays with relatively short wavelengths. Because light waves will scatter, they will become thinner and thinner, the irradiation range will become larger and larger, and the energy contained in light waves will become weaker and weaker. This principle is very important for photography. For example, the brightness of an object that is shot away from the camera 1m with a flash will be about 4 times higher than that of an object that is shot away from the camera 2 meters. This is the practical application of the above principles in photography. 1, the basic characteristics of light, the form of light is different in different periods. All light, whether natural light or indoor artificial light, has the following three characteristics. Brightness: indicates the intensity of light, which varies with the energy and distance of the light source. Direction: There is only one light source, and the direction is easy to determine. In the case of multiple light sources, such as diffuse light on cloudy days, the direction is difficult to determine or even completely lost. Color: Light with different properties will become many colors through different substances. Under the action of natural light, incandescent lamp or electronic flash lamp, the color of sunlight itself changes with the change of atmospheric conditions and time of day. 2. The light in four different directions can capture the photographed object from any side according to the different orientations of the camera, the photographed object and the light source. When the main light source is very strong (such as bright sunlight), from the perspective of camera framing, the projection in different parts of the object will produce different effects, which can be basically divided into five types: top light, front light, side light and backlight. Top light: it is the most unfavorable light for shooting, especially portraits, which are easy to produce ugly light and shadow. For daily shooting, the contrast is large and the stereoscopic impression is not very strong, which is the least ideal shooting light, so photographers usually don't choose to shoot in natural light at noon. However, if used properly, you can still take excellent photos. For example, a black-and-white photo of Madonna taken by Herb Ritz was taken at noon. Front light: The camera is in the same direction as the light source, facing the subject, so that the surface facing the lens can easily get enough light, which can make the subject clearer. According to different angles of light, fairing can be divided into front fairing and side fairing. Forward light is the light that directly shines on the subject along the direction of the lens. The image taken by such light will reduce the contrast of the subject and lack the three-dimensional sense like a plan. Shooting in such light will often lead to unsatisfactory results, which will make the subject lose its original light and shade level. Most of the photos illuminated by airborne flashlights are in this light. Side light refers to the light from the left or right side of the camera to the subject. When shooting, side light is the ideal light for shooting with a single light source. In most cases, 25 ~ 45 side lighting is used, that is, the included angle between the connecting line between the camera and the subject and the connecting line between the light source and the subject is 25 ~ 45. At this time, the part of the subject facing the camera is illuminated, and partial projection appears. This can better express the facial expression and skin texture of the characters, which not only ensures the brightness of the subject, but also makes the contrast between light and dark appropriate and stereoscopic. Side light: The light source of side light is the light that shines on the subject from one side of the straight line formed by the camera and the subject. At this time, half of the front of the subject is illuminated by light, and the shadow is slender, the projection is obvious, and the three-dimensional sense is strong, which can show the grandeur of the building. However, due to the strong contrast between light and shade, it is not suitable for expressing the delicate texture of the subject. However, in many cases, this photometry can well express the texture of rough surfaces. Backlight: the light that the sun is incident on the lens, which tests the anti-halo ability of the lens and the photographer's photometric experience. If you use it well, you can take excellent photos. Second, you can give examples to illustrate the effects of various lights. 1. The direct light is taken under the direct light condition, and the obtained image has large contrast, bright colors and obvious alternation of light and shade. Bright parts, midtones and dark parts are clearly divided, and photographers often like this kind of light. Due to the unique characteristics of direct light, it is easy to produce highlights and projections, which is also a technique that photographers like to use. Many photographers like to use projection to arrange pictures, and also use projection to block elements that interfere with pictures. This photo uses typical direct light, which obliquely enters from the top, and there are layers of projection and reflection from highlights and bright parts to dark parts. The exposure is accurate, the highlight does not overflow, and the dark level is visible.
