A, the mystery of light Photography is the study of the art of light, so light in photography in the use of how light four different orientation is important. Light including all the color, can pass through any transparent objects, and lack of light is produced when the shadows. We don't necessarily go to explore the mysteries of light, as long as the reasonable run out is enough. Light is a form of energy, which, in the form of electromagnetic wave exists in the universe, is one of the many energy. In the form of light wave propagation, the wave of two peaks in the distance between called the wavelength, the length of the wavelength determines the existence in the nature of special forms of energy. As the chart shows, the human to be able to see the light is only a short period of graph bands. We put this kind of light is called "visible", and people don't see in the light, we can only to other forms feel of their existence. We according to the length of the wavelength invented many metering instruments, can not only detect infrared, and still can detect wavelength is relatively short of ultraviolet ray, etc. Because light scatters, so light will become more and more thin, illuminate the scope of will be more and more big, light waves contain energy will become more and more weak. This principle to the photography is very important. For example, using flash shooting a distance 1 m far objects camera, its brightness will than in shooting distance camera 2 m far higher than the brightness of an object for 4 times or so, this is the principle of photography of practical application. 1, the basic characteristic of the light Light in different times form is different also, noon bright sunshine of searing light, cloudy weather in the light of the soft as velvet, through the leaves twinkling multicolored sun clearance, part of the splendid and part is keep out of clouds the sun, rainy weather hazy overcast light, and dramatic mysterious weird moonlight, but all light, whether natural light or artificial indoor light, there is the following 3 point features. · shades: says the strength of the light, the light source and the distance with the energy changes. · direction: only a light source, the direction is easy to determine. And have more than one light source such as cloudy weather the diffuse light, it is very difficult to determine the direction, even totally lost. · colour: different nature of the light, let it through material and change a variety of different colors. In natural light and the incandescent light or electronic flash light color under the action of each are not identical, and the colour of the sun itself with the atmospheric conditions and a day time changes. 2, the light of the four directions According to the camera, be taken objects and light source in different direction, from any side capture to be taken objects. When the Lord strong light source (such as in bright sunshine), from cameras point's point of view, the projection was taken in different parts of the body can produce different result, basic can be divided into five types: top light, positive light, side light, light. Top light: the most detrimental to shooting, especially portrait, easy to produce more ugly lighting, for daily shooting, contrast is bigger, stereo sense is not very strong again, is the ideal shooting light, so usually photographers don't choose at noon on natural light shooting. But if used properly can still taken from the runoff better photos, for example Hector cloth · red watts of Madonna's a punch to the filming of black and white photos taken in at noon. Positive light: camera and light source in the same direction, and to the foreground subject, make its toward the lens face easy to get enough light, can make the shooting object is more clear. According to the light from the point of view of the different, the light can be divided along the side is light and light two kinds. Is the light is the direction of the camera down to be taken directly on the light on the subject. The use of such a light shooting out of the image, the main body of a contrast can be reduced, like plan as a lack of stereo feeling. In light of this film, its effect is often not ideal, can make the foreground subject losing its light and shade arrangement. Most of the airborne flash lighting pictures is the light. And the light is the light from the left or right side of the camera into the foreground subject. In the film, the light is the only light source used camera ideal light. Most cases with 25 ° to 45 ° along side of light lighting, namely the camera and the foreground subject of connections between, and a light source and the foreground subject of connections between 25 ° Angle formed for ~ 45 °. Facing the camera at this time the foreground subject part by light, the emergence of a part of the projection. This can better showing facial expression of the figures and skin texture, not only ensure the the foreground subject brightness, and can make the light and shade contrast is proper, have stereo feeling. Side light: side light of light source is in the camera and the foreground subject to the side of the line of the form, from side to be taken to illuminate the light on the subject. At this time the foreground subject by the positive half light, the shadow is high, projection obvious, stereo sense is very strong, the tall buildings to majestic is expressive force. But because with comparative and intense light and shade, not suitable for performance of the main body is exquisite sense side. But in many cases the metering can be a very good performance of the rough surface texture.
