Color temperature and white balance where different?

Recently a friend asked what is the "white balance", he also heard when using DC shoot things need correcting white balance, because in different environment color temperature is not the same. He would like to know what white balance and color temperature between. Do not know if you noticed no? in shoot under incandescent lamp image color will obviously too red. Was in the eyes of the lighting and daylight color are normal, a friend recently asked what is the "white balance", he also heard when using DC shoot things need correcting white balance, because in different environment color temperature is not the same. He would like to know what white balance and color temperature between. Do not know if you noticed no? in shoot under incandescent lamp image color will obviously too red. Was in the eyes of the lighting and daylight color is normal, it is because the brain will be corrected. Most professional players want to shoot with DC image color and the human eye sees colors as possible. However, since CCD sensors themselves do not have this capability, so it must be doubled output signal, this correction is called the white balance. So color temperature?, in fact, in the field of photography, light mostly according to their color temperature to define. Color temperature is Kelvin, at different temperatures a color is the color temperature. When a black object heated began to glow, it will first become dark red, with the temperature continues to rise will turn yellow, and white, and finally becomes blue (we can see the filament of the lamp, but due to the temperature limit, we generally will not see it becomes blue). In short, this phenomenon in our daily life is very common. For a digital camera, adjustable white balance and color temperature problems, in different light conditions were shooting objects under the color will change. Just to stand, I once in a very complex environment, to a metal housing of the projector to take a look at the results back to find a projector body enveloped. layer Blu-ray I learned to Batman: minimize extraneous light color on the photographed objects, in a variety of complex color temperature conditions are able to correctly restore the original color objects, you need to make the color of the digital camera has to find the correct color balance, this is the so-called white balance adjustment. Most digital camera's white balance options all have more than 5, generally have the automatic mode, daylight, cloudy, incandescent, fluorescent lamps, etc. So we can live in the environment on the camera to adjust, for example in indoor shooting, according to the Interior fittings of the light source to select it, and they have two tungsten lamp and fluorescent lamps, fluorescent lamp mode white objects will too blue. In tungsten mode, the camera's white balance function will enhance the image of the blue, to ensure that the color of the restore. In some advanced DC and DV, if you preset white balance mode not satisfied, you can also use the manual white balance adjustment mode. But before that we need to find a white reference, such as white — something (in fact, you should use 18% grey to adjust, but such things are not too hard to find), you can just use the camera lens on it can be white balance adjustment. Some may ask, why is the white paper, no other color? as long as your camera's white balance system to properly restore white, so that you can restore the color correctly. Do not know if you see that there is no white balance, color temperature and the end is what kind of relationship, you may also be asked, the camera inside the white balance options are adequate, and why you need to manually adjust the? before I actually asked this question. There is a high one, this is professional and amateurs of difference, I was really striking! learn how to correctly use the white balance will allow you to gradually improve your level of photography.
