色温（Color temperature）.doc

色温（Color temperature） Photography said the color generally refers to the environmental temperature of the light, for the yellow eyes, white light color temperature is about 5500K, the lower is warm color (yellow and red), the higher the month cold (blue and purple). In the camera, the white balance (note the white balance of the word, as will be explained below) set the lower picture is blue, the higher the greater yellow, it is necessary to make clear the concept of white balance: The basic concept of white balance is that white objects can be reduced to white, regardless of any light source. Just imagine, if the yellow (color temperature low, set to 3000K) of the light, a white object will appear yellow, then if the camera white balance is set to the 5200K daylight, shot out of the object will be yellow; and if reduced to 3000K, will then be taken out of the white object is white (note, is the original than the original yellow blue), the photos to the landlord so that the color is warm tone more value the greater the smaller values are more blue tone conclusion. In general, it is clear that the color of the light source is the color temperature itself, while the white balance of the camera is aimed at correcting the color bias caused by the light source color, so it is understandable to see the opposite shooting result. White balance is one of the most important concepts in digital cameras. The so-called white balance (English name White Balance) is the digital camera to restore white objects. When we see the universe of 1,000,000,000 universes with the naked eye, in a different light, the same color feeling is basically the same as in the morning, when we see a Tequila Sunrise, white objects, feel it is white; and we at night under the dim light, white objects see, feel it still is white. This is because the human brain has adapted to the color reduction of objects in different light since its birth. However, as a digital camera, there is no human eyes adaptabili
