Live room lighting solutions

Layered lighting is a common way of lighting a studio. This lighting method can enhance the subject and the sense of perspective. The illumination of these three areas is different, the illumination of the front area should be in 2000-2500lx, the illumination of the middle area should be in 1500-2000lx, the illumination of the back area should be in 800-1000lx, the illumination of the canopy light should be in 600-800lx. The purpose of zoning lighting is to give a sense of hierarchy and three-dimensionality.

Different colour temperatures of light can render different atmospheres, for example: colour temperature 3200K light is warm white light, rendering a warm atmosphere; colour temperature 5600K light is white light, it will look serious atmosphere. The cross-use of different colour temperatures can increase the sense of hierarchy and three-dimensionality.

1, lighting procedures generally have three, that is, first cloth character light, then cloth background light, then cloth trim light; can also first cloth background light, then cloth character, trim light of. According to the habits of each person, but no matter which light you first cloth, cloth light to cover up the excess light to avoid mutual interference. For example, when laying out the background light, you should avoid or fix the residual light that shines at the announcer because of the background light, otherwise it will affect the next step of character modelling. Usually arranged background light on both sides of the scene, the front or the reverse side of the upper and lower heaven and earth row type of cloth light, the scope of movement of the light can be based on the structural content of the scene, the light ratio also depends on the scene, some background itself equipped with luminous body, some scenery structure is more complex, and has a convex and concave three-dimensional surface, which needs to be in the cloth light to reflect the characteristics of the scene, but also to consider the shaded scene due to the light irradiation, affecting the choreography effect. Lighting can be used separately, that is, first cloth surface, then cloth point, the use of light ratio, light tones highlight the layers of scenery. The brightness of the background light should be lower than the character light, and the ratio of the character light should be between 1:1.5~2. In short, the background light should be reduced as much as possible, and the excess light should be controlled behind the announcer; the colour should not be too dark and too mixed, and light tones or neutral gray should be used, and the colour should be too heavy to affect the dress and image of the announcer.

2, character lighting. After the background light is set, the background light can be turned off first, for independent character lighting, if two men and two women broadcast, according to the facial features of male and female announcers, to determine the main light position, if two people have large differences in face shape, need to set the main light position of the high and low, positive and negative to determine the face shape. The main light is the main light source of the character modeling, and is an important factor in the expression of the character's form, outline and texture. The general light position of the female announcer should not be too high or too side, especially the announcer with a wrinkled face; the height and side of the light position should be mastered. The position of the main light is generally between 40 and 60 degrees parallel, the height of the announcer sitting, the nose shadow in the nose clip a little below the best If it is a line of high nose, the light position should not be too side, the light should not be too hard, you can use soft paper to soften the light. When laying out the light of the character, try not to scatter to the background, or affect the overall level and effect of the picture; if the light position can not be avoided, the available title leaves to cover, such as title leaves have a vague shadow, you can add black cardboard on the title leaves to lengthen the cover, or use the light blocker.

3, auxiliary light, also known as secondary light, is used to make up for the lack of main light, irradiation of the main light can not illuminate the other side, is to assist the main light to shape the image, increase the texture and facial transition levels, dilute the shadow produced by the main light modeling. The auxiliary light should be a soft light, preferably a trichromatic soft light. If it is a spotlight, you can add soft paper on the title leaf, according to the brightness of the situation can add two layers of soft paper, a layer added to the lens mouth, another layer added in front of the title leaf, to increase the softness, the purpose is to minimise the shadows generated by the auxiliary light; light position can be based on the position of the main light and the face, hair situation, general auxiliary not over the bridge of the nose, otherwise there will be a butterfly-type shadow, brightness to the main light than the auxiliary light in 2:1 ~ 3:1 between is appropriate.

4, face light that is the front of the light, is used to illuminate the front of the character light, light position generally in the height of the character's face on the upper side, in the light position on the throw of about 30 degrees. Can also be used double light face light, that is, first with a soft light for facial lighting, and then with a small light plus eye light, especially if there is a prompter or announcer has obvious eye bags, need to use separate face light lighting. Face light should play: to help the main light modeling, so that the character face has layers, with eye light, the smaller the eye light, the less, the softer the better. Announcer broadcast teeth and tongue to see clearly, but to control the brightness, try to reduce the new shadows, especially the palate shadows and background shadows, otherwise the face looks messy, the picture is not clean.

5, backlighting, also known as contour light, it is used to outline the lines and contours of the character light, is to enhance the depth of the picture, highlighting the spatial level of light of people and scenery, in the shape of the character reflects the texture of hair accessories, shoulder clothing, three-dimensional sense. The light is generally between 45 degrees and 65 degrees in the upper throw behind the announcer, the brightness needs to be higher than the main light, the light ratio should be between 2:1, but should not be too bright, otherwise it will produce a false unnatural feeling.
