1、打开原图素材,先将图片模式转为lab颜色(图像 模式 Lab颜色),并新建通道,填充中性灰。

2、执行:图像 计算,得到绿色选区(如果不勾选反向那就是)即Alpha 2通道。![](http://img.tulaoshi.com/image/20160201/178007fed04476ec9138b23cedab7788.jpg)

3、执行:图像 计算,得到黄色选区即Alpha 3通道。![](http://img.tulaoshi.com/image/20160201/c9f2a9e2ff4baa6020eb5dca84c923c3.jpg)

5、行计算,将黄绿选区合并即Alpha 5通道。![](http://img.tulaoshi.com/image/20160201/06becb95b53dd3b6fbcb86c3ba3555f0.jpg)

6、对新选区即Alpha 5通道执行阴影高光(提亮低饱和度区域),参数设置如下图。![](http://img.tulaoshi.com/image/20160201/c2163d30585bf09e07bb8c35b8c05b79.jpg)
7、按Ctrl + M 调整曲线,参数设置如下图。![](http://img.tulaoshi.com/image/20160201/edf49d57a6eb44f39fdfe7f9af2e6880.jpg)
8、载入Alpha 5通道选区,执行色相饱和度(其实其他命令也行 接着消灭紫),参数及效果如下图。![](http://img.tulaoshi.com/image/20160201/fb5dd10de6eb12917dda198b2abe1b6c.jpg)
