2、查看通道,蓝通道中人体和大部分头发与背景反差大,可用蓝通道抠人体和大部分头发。![](https://img.tulaoshi.com/image/20160201/4f197a27616594b77fd9878f2ec9ec69.jpg)
3、红通道中箭头所指的头发与其相邻的背景反差大,用红通道抠发白的头发。思路已定,下面开始操作。![](https://img.tulaoshi.com/image/20160201/a429f084776c586ae07e9cb9a2fd10ca.jpg)
4、进入通道,复制蓝通道得到蓝副本,Ctrl+I 反相。![](https://img.tulaoshi.com/image/20160201/b0aa87ca0559a09a51655787e6d55fde.jpg)
5、Ctrl+L 调色阶,数据供参考。调到边缘头发变白,背景变黑。![](https://img.tulaoshi.com/image/20160201/0887161ec66db9e1614b2e425bd01339.jpg)
6、设置前景色为白色,用画笔涂白人体和头发。注意发丝间的空隙不要涂。![](https://img.tulaoshi.com/image/20160201/575913f9c4a85f21ad9ed9228a197405.jpg)
7、点击箭头所指,把蓝副本载入选区。![](https://img.tulaoshi.com/image/20160201/191fbcdd178f2ca34bb9ec6212f21f1a.jpg)
8、回到图层面板,选中图层0,Ctrl+J复制得到图层1。在图层0上方新建图层填充蓝色作为检验层。图中可以看出MM基本被抠出。![](https://img.tulaoshi.com/image/20160201/b7e70b0269ab6c21923817154516e40c.jpg)
