人脸修图

用PS打开图片之后的第一步总是复制背景图层，也可以用快捷键ctrl + J。这样做的原因是可以恢复到最初的状态，其实图层就像是一系列操作的集合？！

去污工具

污点修复画笔工具，快捷键J。这个可以用来擦除脸上的痘痘

高斯去噪

1. 复制蓝通道
2. 滤镜-其他-高反差保留；半径：4.0像素
3. 图像-计算；混合：强光。重复3次本步骤
4. Ctrl+鼠标左键 点击通道下边的Alpha 3通道
5. Ctrl + Shift + I反选择

git 常用指令

如何协作

1. git remote add upstream git@...
2. git fetch upstream
3. git merge upstream/master
4. git push

然后在自己的仓库创建新的pull request合并到远程的upstream仓库。
