The direction of light
All the light is directional, the concept is easy to understand. According to sources with the main subject and the relative position of the camera horizontally, the light can be divided into cis-light, backlight, side three basic types; according to the relative vertical position of the three, can be divided into the top light, plunging fire light , Yang-fire light and reflected light four kinds of light.
1, cis-ray
Camera and light source in the same direction, opposite the main subject, so that it faces toward the camera lens is easy to get enough light, can shoot the object more clearly. According to the light from different angles, along the DSC-TX5 battery sony light is along the light can be divided into two kinds of light along the side.
Along the light is along the direction of the camera lens on your subject's direct exposure to light. If the light source and camera at the same height, then, for all parts of the camera lens to receive light, so that without any shadow. Use this light shooting out of the image, the main contrast is reduced, the same as the lack of three-dimensional floor plan. In this light shooting, the effect is often not satisfactory, your subject will lose the shades.
The light is the light from the side along the left or right side of the camera shooting your subject. During recording, the side of the camera along just to use a single light source than ideal lighting. In most cases, we generally use 25 ° ~ 45 ° along the side of light for illumination, that is, the connection between the camera and your subject, and the connection between light source and your subject form an angle of 25 ° ~ 45 °. At this point the face of the camera's main subject in part by the light, there has been part of the projection. This can better demonstration of the character's facial expression and skin texture. Both to ensure the brightness of your subject, but also to properly light and dark contrast, with the three-dimensional.
2, BacklightAll the light is directional, the concept is easy to understand.

Backlight is facing the camera, while the main subject carrying a light source generated light. In the next shot out of the strong backlight image, easy to form the silhouette-like body: body dark and bright around it, the outline of your subject line was particularly prominent.
Backlit film camera has always been a taboo. Backlit film, easy to make people face is too dark, or shaded do not know. Improper use will have the main color is not correct, underexposed and so on. If you are not an alternative sony dsc-w130 battery charger shooting film, then, should avoid lit shots, if you must, under these conditions should be taken to increase the use of reflectors and other auxiliary light.
3, side
Edge-lit light source is formed in the camera and your subject line the side, from side to light the light on your subject. At this point the front half of your subject by light exposure, shadow slender, clear projection, three-dimensional sense of strong, majestic tall the building is very expressive. However, due to the strong chiaroscuro, is not suitable for delicate texture of the performance of the main side.
4, the top light, plunging fire light, light, and Yang-fire incident light
Top light is usually on the part of persons or things to delineate the outline of and background to isolate. However, in the main light irradiation from above the top, make the scene plane, the lack of levels, color reproduction is poor, this light rarely use.
The plunging fire using just the four of them up to a light. General lighting in dealing with the main camera when the light is usually slightly higher than the main light source arrangement, and ground into a 30 ° ~ 45 ° angle position. This light, not only would be enough light the main front, also have three-dimensional, and the formation of the shadow will not be too obvious. If we shun the light with lateral position, with better results.
Along with light-fire is the same light, not very good light. Even in light of the position along the side, formed by the shadows a bit stiff stiff, as plunging fire to natural light. Yang is also a rare incident light lighting method. Up under the light source placed in the main exposure will create an eerie effect.
Light colors
And like everything else, has the same color light, different light its color different. Usually we use to describe the color temperature of light color, the higher the temperature, the more blue components; lower temperature, the orange light of the ingredients the more. But in a different color temperature of light irradiation, the color of your subject will produce change. In this regard, the white object was most nikon coolpix p500 battery evident: in the 60W light bulb, the white object will look with the orange color, but if it is in the blue sky, with a blue hue will be. Camera is by adjusting the white balance to restore the original color of your subject.
