打个比方，通过电子取景器，在拍摄前，你可以看到按下快门后的出片效果(白平衡，曝光，对焦等等)。

For example, you can see exactly what effect your Settings will have before you take the shot (white balance, exposure, focus, and so on).

再次提示，如果你在后期调整白平衡，说明你想得到最佳的照片效果，但这要求照片的光线色温一致。

Again, you'll likely get the best results if you adjust WB during post processing, but this way the images will have a more consistent color throughout.

通过对大量自然图像测试的实验结果表明，该方法能够获得较好的色彩白平衡效果，且计算效率较优。

Experimental results show that, on a large number of natural images set, the method has better color balance effect and better computational efficiency.
