Lighting is widely used in the film and television industry. In many cases, the effects of many TV programs, advertisements, photography or movies depend to a large extent on lighting. When lighting in a TV studio, the light source should be carefully arranged so that the contrast of the images captured by each color camera from different angles will not be too different.
Lighting can be mainly divided into main light, auxiliary light, backlight, top light, background light and so on. The key light is the main light used to describe the appearance and form of the subject. The key light makes the scene receive more light and is more symmetrical, mostly used for basic lighting and background light. The facial features, contour posture, three-dimensional shape, light and shadow changes of the subject are normal, and it is relatively easy to be accepted by the audience. The light source of wide-light illumination is generally at a position of about 60° in front of the subject. Compared with normal main light illumination, wide-light illumination increases the illuminated area of the subject's surface, and the shadow part is relatively large, which helps to increase the brightness of the subject. Wide and narrow face shape, but it's not as expressive as normal key lighting. The light source of the surface lighting is at a position of 75° on the side of the subject, that is, at a position of 15° to the left or right of the shooting position. This kind of light is basically frontal lighting, which is more conducive to explaining the scene and the relationship between the characters and the environment. The disadvantage is that, like broad lighting, it is not suitable for expressing the texture of characters. The narrow light source is located at a position of about 15° to the side of the subject, which is especially suitable for the subject whose texture needs to be emphasized. Attention should be paid to the lighting of the main light. It is conducive to rendering and shaping the atmosphere and image to achieve a reasonable configuration of the tone and tone in the picture and highlight key scenes & characters.
The auxiliary light can add a three-dimensional sense to the characters and scenes in the set, which can highlight the outline of the side and express the shape of the subject; make up for the lack of the main light in the performance, and balance the brightness of the light. Soft and delicate light create proper lighting for dark areas.
Backlight, also known as contour light, is the light that hits the person or scene from the direction opposite to the camera. This light outlines the subject, distinguishes the subject from the background, enhances the three-dimensional sense, and shows the transparency of the scene. and texture. If there is no backlight, the audience will feel as if the actor is attached to the set. The backlight has a strong decorative effect that can form a bright edge around the subject, decoratively Inlaid into a halo, which gives the audience a sense of beauty.
In a large studio or stage, it is often difficult to achieve very accurate and delicate lighting, because hard to take care of each person and every shooting position. Lighting first requires understanding the route and scope of the characters' activities, and the lens used by the camera. Different from the scene, only by adding lamps, and striving to distribute the light evenly. With the change of character activities and scene , the contour light may become the key light, and the key light may become the contour light. In terms of choosing light and color, you can choose according to the plot and the psychological changes of the characters; choose from the perspective of time and space; choose from the perspective of scenery, props, costumes and make-up; To choose the angle of the light source, it is necessary to give full play to the role of light and color, correctly handle the relationship between these lights, and use different methods according to different requirements to combine lighting skills with art.
