Dear you, this is LearningYard Academy.

What Xiaobian brings to you today is<talking about PS series (4) | The use of magnetic lasso tool and crop tool in ps

PART.1.

磁性套索工具似乎有磁力一样，不须按鼠标左键而直接移动鼠标，在工具头处会出现自动跟踪的线，这条线总是走向颜色与颜色边界处，边界越明显磁力越强，将首尾连接后可完成选择，一般用于颜色与颜色差别比较大的图像选择。

裁剪工具用于对图像或者图层进行裁剪操作。

磁性套索的快捷键供大家平时使用：L

裁剪快捷键：C

The magnetic lasso tool seems to have a magnetic force. You don't need to press the left mouse button to directly move the mouse. An automatic tracking line will appear at the tool head. This line always goes to the color and color boundary. The more obvious the boundary, the stronger the magnetic force. The selection can be completed after connecting the head and tail, which is generally used for image selection with large differences in color and color.

The crop tool is used to crop an image or layer.

The shortcut keys of the magnetic lasso are for everyone to use: L

Crop shortcut: C

PART.2.

接下来是磁性套索工具的演示案例：

Next is a demo of the Magnetic Lasso Tool:

1、新建图层，选择需要我们处理的图片。

1. Create a new layer and select the image that we need to process.

2、打开图片，如果我们想要选择眼睛中瞳孔的部位，我们可能首先会想到使用套索工具。

2. Open the picture. If we want to select the part of the pupil in the eye, we may first think of using the lasso tool.

3、这时我们就会发现，一些细节部分使用套索工具很难实现。

3. At this time, we will find that some details are difficult to achieve using the lasso tool.

4、这时，我们就可以使用磁性套索工具。

4. At this point, we can use the Magnetic Lasso Tool.

5、选择磁性套索工具，按鼠标左键点击或者拖动，会发现有磁性的小点自动吸附在选区的边缘，避免我们手动的处理。

5. Select the magnetic lasso tool, click or drag with the left mouse button, and you will find that the magnetic dots are automatically attached to the edge of the selection, avoiding our manual processing.

6、将需要我们处理的部分选择，选择上方工具栏中的选择并遮住，调整羽化值；

6. For the part of the selection that needs to be processed, select the selection in the upper toolbar and cover it, and adjust the feathering value;

7、在图层栏下方选择调整图层，就可以对选区进行调整。

7. Select the adjustment layer below the layer bar to adjust the selection.
