PS实用课程是我从大一下学期开始给社团干事进行的培训课程，本课程本着简单实用的宗旨，主要向没有PS基础的初学者教授一些简单易学的PS技巧，同时将一些PS的基本知识教授给听者。
目前处于实用篇的第一章：抠图。抠图的目的很简单，就是将图中的某个部分与其他部分分开。这样就可以将抠图的方向分为两种，一种是将主体从背景中取出，另一种就是将背景去除。
本次给大家分享的是第一课：基础抠图。涉及到的内容主要有：套索、魔棒、快速选择、文字工具、滤镜（及基本操作）。附上讲解配套的PPT以及相关的素材给大家练习。
以后可能会出具体的语音以及文字教程，看心情吧。

This can be the direction of matting is divided into two kinds, one is the main body is taken out from the background, the other one is the background removal.
This is the first lesson to share: basic matting. The main contents are: the lasso, the magic stick, the quick selection, the text tool, the filter (and the basic operation). Attach a complete set of PPT and related materials to practice. In the future, there may be specific phonetic and text tutorials to look at the mood.
