What is the use of masks in PS?

Mask is a style of layer in PhotoShop drawing software. Masks in PS convert different grayscale color values ​​​​into different transparency, and apply it to the layer where it is located, causing corresponding changes in the transparency of different parts of the layer. Black is completely transparent and white is completely opaque. In fact, in real-life drawing or design, it is often necessary to protect a certain area to prevent subsequent operations from contaminating this area, so a mask is added to this area. This is the role of the mask in physical work. It has many functions, and I will take you through some of the main functions below.

Because Adobe knows that designers’ imaginations are endless, it does not provide a tool called “Fade Tool” or “Reflection Tool”, but provides Created a "mask" that can generate tens of millions of possible uses.

Several main functions of the mask:

1. Fade

If you add a Mask, then pull a gradient from white to black from top to bottom, and the result is a layer that gradually disappears from top to bottom.

2. Reflection

If you copy a layer and flip it vertically, then move it below the original layer and add a mask to pull it Gradient from white to black, you can get a projection of the original layer, this application is very wide.

3. Protect the original layer

We may need to partially erase a certain layer in actual operation, but if we use the eraser If you use this type of tool, the operation on the layer is irreversible. If one day we need to restore the erased things, we will really regret it. So we can create a new mask for the layer that needs to be erased. There are many ways to erase it. For example, use the marquee tool to select a certain area, fill the mask with black, or use the brush tool to select black, and then After selecting the mask, directly modify the layer, so that the painted part will be hidden by the mask, and the same effect of erasing can be achieved.

4. Cut out pictures

Sometimes we need a certain part of a certain picture, but there are many pictures that are very difficult to process. At this time we can only Use the mask combined with the brush to erase bit by bit.
