Camera lecture time to today to say "white balance" function of the camera，The
That the white balance is white or nearly white to the end of the reference value for a digital camera reference，Why is the digital camera a white reference value?
This，Digital cameras photosensitive components depending on the color does not look like the human eye can immediately amend，Human beings see white even if the non-white，However, we still identified as white，但是數位相機可就不一樣了，Give the color of the sensor through the light source，Makes a digital camera captured images is given after the light source color image，That is digital camera, then there is no "white balance" function，According to a direct incandescent light bulbs
Of the white paper，The resulting image is a light yellow White，Average non-ideal outcome 這樣，Be different with our cognitive，So this time on the need to "balance" function。
Early camera white balance this feature，Record in the film which，But the film's white balance is fixed，Can not make any changes；Now science and technology，The market, the majority of digital cameras built-in white balance function，White Balance
As important as the function is equal to the aperture and shutter，If theThe shutter is a dynamic image depends、Aperture is to determine the brightness of the image，That white balance can be said is to determine the brightness of the image color。
Usually in the hot sun camera does not set the white balance for such functions，Light enough to make the color of the subject is more clear and obvious，But like in other cloudy、Fluorescent、Burning light or light sources of different ground etc ...，The color of the subject through these light showing different colors，We obtained non-cooperation 們看 caused 來會 remembered standing out shining effect 來的 這樣，So when the white balance in different lighting conditions with a suitable，Not only the whole image becomes more clear and natural，You can also try with different white balance，Sometimes do not need filters can also illuminate the image with Vision dye effect.
