PhotoshopOf Layer maskThere is no doubt about the importance of Layer Mask in image processing. it is a magic "magic wand" in Photoshop. let me teach you how to master this "magic wand.
　　 What is a layer mask?
A Layer Mask is a gray-scale image that is attached to a Layer to cover the area at the top of the Layer and display the image at the bottom of the Layer.
The black part of the mask makes the image of this layer transparent. you can see the lower layer. Therefore, if we select "hide all" when creating a new mask, we will be able to get a full black mask.
The white part of the mask, indicating that the image of the current layer is not transparent and blocks the lower layer. Therefore, if we select "show all" when creating a new mask, we can get a completely white mask. The display and hide here are for this layer.
Gray indicates that the layer is semi-transparent, and the following part can be seen.

　　 Add a layer mask to a layer
A mask can be added to each layer, whether it is an image layer, a text layer, a palette layer, or a variety of special effect layers.
To Add a mask to a layer, first select the layer to be masked, and then click Add a mask on the layer board, you can also click Layer/Add a mask to Add a Layer mask/Reveal All display command. in this way, you can Add a full-white mask. Therefore, the entire Layer is not transparent and will be displayed in full. If you press and hold the Alt key and then click the Add a mask button, or click Layer/Add a mask to Add a Layer mask/Hide All to Hide the display, a full black mask will be created to Hide the entire Layer. If you want to create a Mask when there is already a Selection range on the Layer, you can execute Layer/Add Layer Mask to Add Layer Mask/Reveal Selection to display the Selection command, you can hide all unselected images. If you perform Layer/Add Layer Mask to Add a Layer Mask/Hide Selection to Hide the Selection, you can Hide all the selected image parts.
　　 Edit Layer mask
A layer mask is an 8-bit grayscale image. if it is black, it indicates that the layer is transparent. you can see the lower layer. if it is white, it indicates that the layer is not transparent. If you want the layer image to be semi-transparent and the local and lower layers to perfectly combine, you can apply the gray color. So if you want to edit the layer mask, you can select any tool or instruction that can be filled to replace the mask coloring. The relationship between the desert and the green grass with the mask in the previous instance is obviously seen.
　　 Close layer mask
If you need to temporarily Disable the Layer Mask, press the Shift key and click the preview of the Layer Mask in the Layer control panel or execute Layer/Disable Layer Mask to Disable the Layer Mask, A red X mark is displayed on the layer mask preview on the layer control panel, indicating that the layer mask is temporarily disabled. At this time, the layer image can be fully displayed. To re-open the Mask, click the Layer Mask preview in the Layer control panel, or execute the Layer Mask command to open the Layer Mask of the Layer/Enable Layer Mask.
　　 Link between a layer and a layer mask
By default, the layer and the layer mask are connected, so the layer and the layer mask can be moved or deformed at the same time. In the layer control panel, a connection icon is displayed between the layer and the layer mask, indicating the connection between the two. Click the connection icon to remove the connection between the layer and the layer mask, so that you can edit the layer mask individually. To restore the connection relationship, click the position between the layer and the layer mask. the link icon appears again, and the layer mask are connected again.
