Lighting set-up process referred to as Although a complex scene from the 100 to light the lighting division there were 100 different programs and results, but several principles of light cloth is all of us will follow. For and interior photography, there is a famous and classic light the theory is the The author briefly outline:
three-point lighting, also known as area lighting, general lighting for the small range of scenarios. If the scene great, it can be split into several smaller areas of light cloth. General there are three lights can be, respectively, as the main light, the auxiliary light and background light.
main light: usually use it to illuminate the scene with the main target of the surrounding area, and served as a principal object projection function. The main relationship between light and dark light from the main decisions, including the projection direction. Of the main tasks of light can also be used Jizhan Deng needed light to work together. If the main light 15 degrees to 30 degrees in the position, said Shun light; at 45 degrees to 90 degrees position, known as the side light; at 90 degrees to 120 degrees on a side of the backlight position. Light used to complete the main spotlight. I like to set the brightness of the main light is about 240.
assist light: also known as fill light. Irradiated with a fan-shaped reflector spotlight, to form a homogeneous, non-direct nature of the soft light source, use it to fill shadow areas and the scene was missing the main areas of light, to reconcile the contrast between light and dark areas, while the depth of field and can be formed level, and this wide range of features make it even distribution of light hit a layer of background for the scene to define the tone of the scene. Since the soft lighting effects to achieve, usually only the main secondary light brightness of 50% -80% of light.
background light: its role is to increase the brightness of the background to set off the subject, and to the main object and background separation. General use of floodlights, the brightness should be dark not too bright.
light the order is: 1) pre-determined position and intensity of the main light; 2) determine the intensity and angle of auxiliary light; 3) distribution of background light and decorative light. The resulting optical effect fabrics should be able to prioritize and complement each other.
light arrangement there are several places in need of special attention:
1) should be fine not more than lighting. Too much light makes the work process has become disorganized and difficult to handle, display and rendering speed will be seriously affected. To retain only the necessary lighting. Also pay attention to lighting and shadow map projection and texture mapping utility, where the lights can map the best alternative to do with the map. For example, the performance of the evening to see the windows from inside the room the appearance of the effect of brightly lit, with a self-luminous map will be much more convenient to do, the effect is also very good, rather than not to use the lights to simulate. Avoid light cloth readily, otherwise the success rate is very low. For optional lighting, we must resolutely not be retained.
2) light and dark to reflect the distribution of the scene, there must be hierarchy, must not deal with all the lights Yi Gai. According to the need to use different types of lighting, such as the use spotlights or floodlights; under the lights need to decide whether the projection, and the concentration of the shadow; need to decide according to the brightness and contrast of light. If you want to achieve more realistic effects, be sure to light attenuation in terms of 下一番功夫. Temporary closure of some of the lights can be used to correct the interference method for better lighting on the other set.
3) to know MAX is the light in the ultra-realistic. To learn to use the light of the For example, to simulate candle lighting and projection effects, we usually put in the position of the candle wick a floodlight. If this is the main light projection does not rule out the candles, then the candle body produced in a large dark shadow on the desktop may make our problem a long time. In the architectural renderings, also often through the
4) distribution of light should be followed by the subject to local, from simple to complex process. For the formation of lighting effects, you should set the main point to emphasize style, and then adjust the attenuation characteristics of light to enhance a sense of reality. Finally, adjust the color of the light make detailed changes. If you really want to speak to simulate the effect of natural light, you must also have sufficient natural light deep understanding. To do more photography books run out and do more tests will be helpful. Different occasions with a light cloth light is not the same. In 室内效果图 production, in order to show the effect of a magnificent, often some of the main color of the light will be set to light orange, can achieve the effect of material not easy to do.
