What is a mask in Photoshop used for and how is it used?

There are two fierce plates: fast and layered.

Quick is used to make a selection, and Layer Plate is used to make a layer mask, which is similar to the Eraser tool, except that you can draw back the erased ones.

Layer mask is a mask meaning, when you add this layer mask to a layer, you can do this layer mask separately (not a layer, is the layer mask of this layer), draw the place with black, indicating that you don't want this place, don't want it at all, and paint the place with gray, indicating that you want a part of this place, which is translucent, if you just painted it with black you suddenly want to come back, Then paint back in white (you can do this with a brush or eraser or a selection fill).

To sum up, the top of the layer Meng board is: black represents nothing, white represents existence, and gray represents half existence and half nothing. This concept fits in the whole PS.

Rapid Mengban means constituency. You should know that there are too many ways to make a selection, the most direct rectangular (circle) selection tool, and what pen path to selection, or what channel to transfer selection, this quick Meng board is the same as them, it is used to make a selection, the difference is that you can use this quick Meng board with filters, or commands under the image, you can get a very strange and interesting selection, so as to make a good preparation for your following special effects.

Having said this, I don't know if you understand, if there is anything you understand, let's discuss it again.

In short: a mask is a white sheet of paper that can adjust its transparency, and it only works with the lower layer, if it has a transparency of 100, which is white, then we can't see anything else through it, like a wall

If it's 0 transparent, i.e. black, then we can see through it and it doesn't matter if it's there

If it's 50 transparent, then we can see through it the next layer, dimly

Masks are typically used in layers with content. Click the Add Mask button (located in the bottom left corner of PS, the one with a circle in the box), it is white by default, it can be changed to black, white display, black masking.

The use of the PS mask function is to open two ** and drag one of them onto the other; Then click on "Mask Tools"; Then click the "Brush Tool", select the color black, and the ** below is displayed in the place where the painting has been drawn; Then change the color of the brush to white, and change the place where it has been painted to the upper layer. If you want to increase your income, if you want to fix a satisfactory **effect, if you want to make a satisfactory**, you must learn to use PS, become a master of cartographic retouching and drawing, choose a PS tutorial course, and quickly learn and master PS.

Start by opening two ** in PS and then drag one of them onto the other.

Then click the Mask tool in the bottom right.

Now let's select the "Brush Tool", select the color black, and draw a stroke on ** to see the effect. You can see that the place where the painting has been painted shows the ** below the spring.

We changed the brush color to white and painted where we had been painted to see the effect. You can see that the place that has been scratched by white has become the upper layer again.

So it's not hard to understand that the layer mask only acts on one layer, giving people the feeling of occlusion on top of the layer, and more importantly, the operation of the mask will not change the original layer image.

The above is "how to use the PS mask function", you can follow the tutorial to operate. Follow other articles to learn PS together.
