Very effective! Ps matting introductory tutorial, telling you how to matting the fastest steps.

Cutout is the most basic operation in PS. Students who want to learn PS must learn it first, and they can cut it out accurately and quickly after repeated practice. In fact, it is not difficult to cut the picture. All you need is patience. Today, Bian Xiao is going to teach you a PS quick matting course, taking the flame as an example, which is an entry-level course. Let's study together!

1. Generally people will use methods such as color filtering when using this kind of material, but you will find that the color filtering mode will cause problems such as brightness and color difference. With the general matting method, you will find that black often remains. The solution is to rebuild the color channel and remove the black part inside.

First open your channel tab.

2.ctrl+ left mouse button click on the thumbnail and select the red channel.

3. Go back to your layer label and create a solid color layer with the selection.

4. Fill with pure red, hide the newly created red solid color layer after filling, and establish corresponding solid color layers for green and blue channels according to this method.

5. As shown in the figure, the following effects are obtained.

6. Change the layer mode of these three layers to filter and merge.

7. In this way, the object is pulled out from the pure black background.

The final effect:

How to dig out the flame in ps? Eight efficient and quick methods

It is required to dig out the flame and finally put it on a blue background. Friends, are you ready?

1, light mixed mode pinch flame (false pinch)

Create a new transparent layer and fill it with blue as the background;

Copy the background picture, put the background copy on the top layer and set the mode to light mode.

Effect:

2, color range pinch flame (true)

Effect rating: general

Create a new transparent layer and fill it with blue as the background;

Copy the background image and put the background copy on top. Click on the background copy with the mouse, then select-color range-highlight, and then hold down Ctrl+J to dig out the highlight flame.

Then continue to click on the background copy map, execute selection-color range-midtone, and then hold down Ctrl+J to dig out the midtone flame.

Comments: The command of color range is actually not suitable for matting and retouching. Its commands for highlights, midtones and shadows mainly tell you the approximate range of highlights, midtones and shadows, and play an indicating role.

3, mixed ribbon digging flame (true digging)

Effect score: the color is too natural and very good.

Create a new transparent layer and fill it with blue as the background;

Copy the background picture and put it on the top floor. Double-click the background image to get the layer style dialog box. Hold down the ALT key and click on the half black block on the right side of the black block on the left side of the color mixing layer, and pull it to the position shown in the figure.

Rendering:

Comments: This method is still too rough! Although the highlight is nominally selected, in fact, a large number of midtones and a small number of dark tones are also selected. Of course, the application in this example is not bad.

Since some students mentioned it above, I will talk about the defects of fake digging. Many people say: it's so easy, this kind of flame color filtering can be done in one step!

Is that really the case? If the background is lighter than the flame, I see how you can do it in one step!

Color filter renderings: it should be said that it is not satisfactory.

Of course, for some matting with white background, front superposition is usually used, and this dilemma will also be encountered. Therefore, any method is not omnipotent, and it has its own special circumstances.

5, red, green and blue three-channel color filter reconstruction flame (true dig)

Effect score: very good!

Create a new transparent layer and fill it with blue as the background;

Copy the background picture and put it on the top floor. Click the background with the mouse to copy the image, go to the channel, load the red channel selection, then create a new transparent layer, select 255 0 0 red fill, and then close the small eyes in front of the fill layer.

Click the background copy map, go to the channel, load the green channel selection, then create a new transparent layer, select 0 255 0 green fill, and then close the small eyes in front of the fill layer;

Click the background to copy the map, go to the channel, load the blue channel selection, then create a new transparent layer, and select 0 0 255 blue fill.

Finally, open the small eyes in front of all layers and change the blending mode of the top two layers to color filtering. Finally, close the small eyes of the background copy layer and hide the background copy.

Rendering:

Evaluation: This is a common method to reconstruct pictures.

Why is black not reconstructed in this example? You can think about it and combine the essence of the channel.

6. The calculation command selects highlight to rebuild the flame (true digging)

Effect score: very good.

Rendering:

Create a new transparent layer and fill it with blue as the background;

Copy the background map, put the background copy on the top layer, click the background copy map with the mouse, and perform image calculation. These parameters are as follows:

Then click on the background copy, enter the channel, load the alpha 1 channel, press and hold Ctrl+J to copy, and then press Ctrl+J 6 times to copy 6 layers of translucent highlight flame. Finally, hide the background copy layer. Of course, you can merge all the translucent layers on it.

Layers panel:

Comments: The previous method of selecting highlights by Ctrl+Alt+2 actually selected some midtones with few shadows. But the calculation command can overcome this defect.

7. Cut off the black range and keep the flame (true)

Effect score: not bad.

Create a new transparent layer and fill it with blue as the background;

Copy the background picture and put the background copy on the top floor. Click the background with the mouse to copy the picture, and select the color range with the following parameters. Then click OK in the black part of the picture, and then press and hold delete to delete the black part.

Rendering:

Comments: Although the color range is often too stiff, I have to admit that it is not bad in this case.

8. Calculate and generate the gray channel key flame (true key)

The principle of this example is similar to that of method 4, which uses ctrl+alt+2 to select highlights and extract flames, but it is easier to understand.

Effect score: not bad.

Rendering:

Create a new transparent layer and fill it with blue as the background;

Copy the background image, put the background image on the top, click the background image with the mouse, and calculate the image:

The purpose of this calculation is to generate gray channels. Gray images and achromatic images of pictures are usually different. Although they all become black and white images, the algorithms are different and the results are different.

Then click the background to copy the layer, go to the channel, load alpha 1 (gray channel), then go back to the layer palette and press ctrl+J to copy the selected part, and then double-click ctrl+J to copy the three-layer translucent flame three times. Finally, hide the background copy layer.
