The key light can render the atmosphere of the picture, shape the character image, and achieve the beauty of the appearance. At the same time, the main light causes the main shadow, revealing the outer shape, surface structure and texture. Primary rays actually or otherwise come from a local light source or from an unspecified but acceptable light source. The effect of a surface light is the same as that of an edge light. It eliminates unlit dead spots in the picture and achieves a frontal full shot. At the same time, it is mixed with other lights to adjust the light ratio, reduce or increase the contrast of brightness, and make the shadows of faces get better texture performance. Brightness contrast creates some night scenes and other effects.
Auxiliary lights: Also known as subsidy lights or auxiliary lights. It is a soft light without shadows that adjusts the light scale, reduces harsh shadows cast by the key light and expresses details on the dark side. Ideally, the secondary light preferably does not alter exposure, or create messy shadows or disrupt the effect of the primary light. Also, secondary lights should be the same as all lights and should be able to be turned on without affecting the shadows or shape of the picture. Strong side lights are often used to compensate for unsightly or unsuitable shapes caused by improper placement of the main light. Secondary light also plays a role of modification in the picture and is modified on the basis of the main light and the total light to deal with the surface structure, three-dimensional and spatial of all or part of the object. In the tonal configuration, his main role is to enhance the brightness interval of the large picture and enrich the picture level. In terms of color, fill light is the main means of color balance.
Modified lights are basic lights, such as key light, fill light, and backlight, and have basic light adjustment effects. However, due to the nature, color and shape of the characters, costumes and props, some subsidized light is required. The features of the costumes and props are highlighted without affecting the base tone, this is called a touch-up light. The light from the eyes creates a flare on the person’s pupil through a reflection relationship, making the character look good and feel realistic. Because the master has no gods. The visual sense can be expressed with the eyes, so the light of the eyes is very important. The frontal side light accounts for 75% of the face: 25% of the light-dark distribution ratio, ideally showing the three-dimensional shape and angle of the face. Thinner characters reduce height, reduce the angle of the light position, and get closer to the camera, allowing for a richer performance for both; flat faces increase angles and enhance facial contours and three-dimensionality. Through angle adjustment, the physiological defects of some subjects can be compensated.
The side light makes the human face forms a light and dark brightness, highlights the character’s forehead, the bridge of the nose and the outline of the lips, causing obvious spots, making the three-dimensional shape of the human face very solid, giving a deep, firm and Powerful feeling. In news lighting, the light is usually distributed to the workers of the factory.
The backlight and camera are oriented in opposite directions and illuminate the subject from the back, so foreground people can be separated from the background to highlight head and shoulders, outline, and highlight depth between the subject and the subject. background. Makes the character look angry without being boring, and the picture is very bright. Especially in close-up and close-up shots, it can show halos in brighter parts, adding to the beauty of the image. So there is basically no backlight when photographing objects, especially people. The reversing lights mainly highlight the character’s head, neck and shoulders, and outline the character’s three-dimensional silhouette. It has a three-dimensional effect and is separated from the background for a sense of space. If the character has less backlighting on the sides, it may create bright spots on the character’s forehead and cheeks, creating a strong daylight effect.
