The characteristics of studio lighting distribution
The main light energy renders the image effect atmosphere, shapes the character image, and meets the requirements of styling beauty. At the same time, the main light energy causes the main shadow to show the external shape, surface structure and texture. The main ray or surface can actually come from a local light source (such as day and night through windows, sunlight, lighting, etc.) or from an unspecified but acceptable luminous body. The function of the surface light is the same as that of the side light. It eliminates the blind spots of the screen and obtains a positive overall illuminance. At the same time, it mixes with other lights, adjusts the light ratio, and reduces or increases the brightness and contrast. Therefore, it is believed that the shadow of the human face can obtain better texture performance. .
Brightness contrast can create some night effects. For example, a low contrast can make a thin face look plump, and it can also eliminate facial wrinkles in some elderly people. Auxiliary lights: also known as subsidy lights, auxiliary lights. It is a soft light without shadows, used to adjust the light ratio, weaken the rough shadows projected by the main light (to reduce the contrast between the bright part and the shadow part) and express the details on the dark side. Ideally, it is best not to change the light exposure to avoid creating chaotic shadows or destroying the effect of the main light source. In addition, the light source should be the same as all light sources, and it should be able to be opened separately, without obstructing the shadow or shape of the image. The strong auxiliary light source is usually used to compensate for the ugly appearance of the main light source or the position error caused by the incorrect shape. The auxiliary light also plays a decorative role on the screen. It will be modified according to the main light and the entire light, and it will process the surface structure, three-dimensionality and space of all or part of the subject.
In the halftone configuration, its main function is to enhance the brightness interval of the large screen and the rich picture level, which is the main means of color and secondary light color balance. Modified light is determined by the original main light, secondary light, backlight and other basic light types, and has basic light effects. However, due to the different nature, color and shape of characters, costumes, and props, certain lighting subsidies are required. On the basis of not affecting the basic color, highlighting the characteristics of clothing and props, this light is called a modified light. The light of the eyes is through the reflection relationship, causing spots in the pupils of the eyes of the characters, making the characters glow, and the emotions are lifelike. Because the owner does not have God in his eyes. The eyes are used to express the feeling of expression of the image, so the light of the eyes is very important. The front light in the face of the character forms a ratio of 75%: 25%, and the ideal way of expression shows the three-dimensional shape and angle of the face of the character. Thinner characters can reduce the height, reduce the angle of the light, and bring the camera closer, so as to have a rich expression; the face of the character is flat, and the angle can be expanded to enhance the facial contour and three-dimensional sense.
The physical weakness of some subjects can be compensated by angle adjustment. The light from the side makes the character’s face half-bright, highlighting the contours of the character’s forehead, nose and lips, producing obvious spots, making the three-dimensional appearance of the character very solid, giving a deep and determined impression. , A powerful feeling.
In news lighting, factories often give workers this kind of lights. The backlight and the camera are in the opposite direction, from the back to the object to be photographed. This will be able to separate the foreground and the background of the character, frustrating the character’s head, shoulders, contour lines, highlighting the depth of the space between the subject and the background, making The character looks angry, not stiff, and the screen is very translucent. Especially at close range, a kind of halo appears in the light part of the close-up lens, which increases the beauty of the image. Therefore, when shooting objects (especially people), it is basically backlit. The ceiling light mainly dampens the neck and shoulders of the head, and outlines a three-dimensional figure with a sense of three-dimensionality, separated background, and a sense of space. If there is less backlight on the character's side, sharp points can be formed on the character's forehead and cheeks, thereby producing a strong sunlight effect.
When the character continuously rotates and the camera is 90 degrees, it can be used as the main ray to highlight the three-dimensional lines of the face. It can give a strong sense of fortitude than using proper light.
The background light is the synthesis of the scene light processing (that is, the background full light, the ambient light and the sky movie, the main light, the decorative light, and the contour light). The main task of ambient light is to show the time, place and specific atmosphere, frustrating people's activities. The order and tone of the background play an important role in the character, especially in the close-up and close-up of the character, the background function of the collection returns to the second one, and the role of the character is the tone that is highlighted in the background.
Lamp set for cold light: News and interview program light adopts the most advanced three-color cold light in the world, with low power and stable color temperature.
The current lighting layout design has been able to meet the requirements of various program productions, and has reached the national jgj/t16-92 fabric lighting standard, and has the characteristics of advanced, practical and reliable, and at the same time complete and diverse.
