When after choosing “sample color”from the option list, the accuracy degree of the chosen sector’s “color difference allowance”value can be adjusted. The bigger “color difference allowance”value, the bigger area of the chosen sector, would conversely become even smaller. Through the use of “after all color” matting process, the operation of “ Color Range Cutout” is very simple. Especially to the background scene and foreground scene with sharp contrast images, it could show even more of its advantages. To those background scenes without the foreground scene simple images, also background scene and foreground scene with an obvious color difference, and also if the background is an individual scene, then the “ Color Range Cutout”can be chosen. 替你翻译好了，希望会满意。
