### 1、加载图片 ###

*  直接拖拽
 *  文件-打开![20200406113029601.png][]
 *  在一个文件中添加多张图片（图层）：置入

### 2、调整曝光度对比度——色阶 ###

三个滑块，对应低灰度、中等灰度、高灰度区域；左滑图像变亮，右滑图像变暗

### 3、调整对比度——曲线 ###

用鼠标点击中部可以固定曲线，通过调节可以提高对比度；

### 4、图像-调整-变换（可以渲染图像） ###

### 5、图像变黑白 ###

*  使用“去色”
 *  “黑白”，点击“色调”，调节色相和饱和度

但是有一点需要注意，图像调整后，就不法进行还原（除非在历史记录中撤销），为了解决这个问题，我们可以“创建新的填充或调整图层”![20200418094225108.png][]，不会破环原始素材。

命令会对下方的所有图层进行变换，如果不想对某一图层变换，可以将该图层移动到上方，这种方法比较粗暴，不太实用。我们可以通过右键选择![20200418095703744.png][]，此时该图像调整命令只作用于下方的第一个图层。
