教程思路:
运用Photoshop“高反差保留”和计算突出斑点,用中性灰色限制对细节的改变并且平滑过渡。
循序渐进,逐步减弱斑点,最后进行调色等其它美化操作。
原图和效果图如下。

1.打开图像,进入通道调板。复制蓝通道。

对蓝通道副本执行 “滤镜\其它\高反差保留”。

用吸管工具吸取邻近的色然后用画笔覆盖如图所示的要保护的部分。包括眼、鼻、眉、嘴、发丝的阴影细节。

图7
按住 Ctrl键用鼠标点击Alpha1通道载入选区,Shift+Ctrl+I反选。
返回到图层调板点击激活背景层。然后建立一个曲线调整层,调整曲线,边观察图像的变化。
此时不急于完全去掉斑点,只是将它们大幅度减弱。
因为下面还要重复一次前面的操作。(新手注意直接按曲线的输出输入参数输入数值)。

按Shift+Ctrl+Alt+E组合键盖印可见图层,对它重复一遍前面的操作。
后面的操作参数凭自已的观察来进行。把握的原则是全部进行微量的调整。
达到保持图像影调色调平衡,去斑效果更好的目的。
且慢!我们发现暗处有些黄色的色斑——包括脸上的发丝。
在工具箱中取海绵工具,模式选项为去色。设一个较小的数值小心擦拭色斑。
然后用画笔工具,选取邻近的颜色上色(画笔用颜色模式)。
