在各种不同的光线状况下,目标物的色彩会产生变化。为了尽可能减少外来光线对目标颜色造成的影响,还原出被摄目标本来的色彩,这就需要对数码相机进行色彩校正,以达到正确的色彩平衡。光谱中性的白色物体因反射了全部的可见光谱,所以数码相机把它作为调整的标准,只要在拍摄白色物体时正确还原物体的白色,就可以在同样的照明条件下正确还原物体的其他色彩,因此称为白平衡调整。
In a variety of light conditions, the color of the target will change. In order to minimize the impact of external light on the target color, restore the original color of the subject, which requires color correction of the digital camera in order to achieve the correct color balance. Spectral neutral white objects reflect the entire visible spectrum, so digital cameras use it as the standard of adjustment, as long as white objects are correctly restored when shooting white, you can correctly restore the rest of the color under the same lighting conditions , So called white balance adjustment.
