This is a cool and useful tip, and for a novice Photoshop friend, mastering this technique is not difficult, but first you should know the basics of the layer and be familiar with some of the commands in the Layer menu.
The problem we often encounter is that in Photoshop, there is an image that is made up of several layers, and we want to create a new layer with the original layer, the new layer is merged by the original layers, and the advantage is that When we feel that the resulting composite image is not very satisfying, you can also modify the original layer until the requirement is met. This tip may not be known to some veteran.
