WHAT DOES MASK MEAN IN PHOTOSHOP CS4?

My understanding is also a simple masking effect, like putting a piece of gauze on another object, and looking at the object from the outside, this effect is called the function of a mask Let's use an example, for example, a painter sprays paint on a billboard, then they will first cover the billboard with a piece of cardboard or plastic board with hollowed-out words, and then spray paint on it. When you remove the cardboard or plastic board, you will see spray-painted words on the billboard. Then the function of this cardboard or plastic board is to mask the board.

The foreground and background layers are the foreground color at the top and the background color at the bottom.

The mask is just below them, and the layer is also available on the panel.

Masks are used for special effects, simply put, they can be used for occlusion and superposition. Backups are just one layer of replication for the sake of finering.

The mask is the outside of the marquee (the inside of the marquee is the selection). The word mask itself comes from the application of life, which means "the board on which it is covered".

The mask is the part outside of our constituency that protects the contents of the constituency. Since the place where the mask is covered is not affected when we are in the district, it needs to be left intact.

Therefore, it needs to be displayed on the layer (as seen in the general map), and from this point of view, the black (i.e. protected area) of the mask is completely transparent, the white (i.e. the selection) is opaque, and the gray is in between (partially selected, partially protected).

PS masks are mainly used for special effects on the created mask layers.

1. Fill the white area on the mask quietly to fully display the image on the current layer.

2. The black part of the mask does not show the image on the current layer.

3. The gray color is a half-display image on the translucent current layer.

4. The three colors of black, white, and gray on the mask only indicate the amount of transparency, and will not add black and white or gray, so the color on the mask will also be displayed as gray digging color.

5. Gray can be painted with multiple gray levels, so you can also use the Add tool to pull out the display effect of the current layer on the mask.

6. Understand the above principles, for example, you can copy a layer, make a blur effect on the copied layer to make the ** more delicate, and other parts that do not need to be blurred, such as the background of the clothes, can be masked with black, so that the image on the original layer can be displayed, and the eyes and mouth can also be painted translucent with different grayscale gray.
