Use layer masks in Photoshop to expose or hide elements of a layer selectively. A white rectangle indicates this attribute. It appears next to the layer mask thumbnail. You may make a mask with the “Add layer mask” button in the Layers panel.
White areas of the layer mask will disclose the layer. Similarly, black areas will keep it hidden. You can selectively hide or show parts of a layer through this. You can undo the changes to the layer mask anytime. This editing method is considered non-destructive.
With this, you can blend two photos or apply a selective color effect. In Photoshop, using a layer mask is very useful. They permit targeted, highly customizable changes to specific layers.
With the vector mask tool, you can give a layer a clean, defined outline. A shape’s “skeleton” path can change with the Pen or Shape tools. Pixels in the layers are available or invisible depending on the geometry of the masks.
The quality of a vector mask will not degrade. This is completely resizable. You can change the underlying layer without worrying about breaking the mask. Logos and symbols benefit greatly from using vector masks. The mask makes the images with sharp corners.
