1. First, we open the PS software and find the lasso tool in the toolbar on the left. Holding down the mouse, we can see that three lasso tools are hidden under the lasso tool icon.
2, the first lasso tool, its use is relatively easy to understand, just use the mouse to draw a lasso to trap the picture to be edited and automatically close the selection;
3. The second lasso tool is called polygonal lasso tool, which is more than polygonal lasso tool. Therefore, when using this tool, you need to draw points manually to select the object to edit. Like matting, you can be specific to the edge of the object, which is no problem, but because it is a polygon, you can't draw an arc, so when using the polygonal lasso tool to matting, try to make the object at right angles.
4. The third lasso tool is called "magnetic lasso tool", which, as the name implies, automatically attracts around the object like a magnet. Click "Magnetic Lasso Tool", click on the edge of the cropped image, release the mouse and start to move the mouse along the edge of the object, so that the edge of the object can be automatically absorbed for matting, which is extremely fast. Clicking the mouse will close the selection area, which is not suitable for objects with complex background, because it will be automatically adsorbed by the background.
I hope the above answers are helpful to you and hope to adopt them!
