1, open PS and create a layer;
2. Then open the graph to be deducted in PS;
3. Then right-click and select the magic wand tool in the matting tool. The magic wand tool is easier to control than the quick selection tool above. If the selection area is large when you buckle, you can also hold down the Alt key and drag the mouse to reduce the area.
4. The selected picture is like this, surrounded by ant lines, followed by matting;
5. Select the mobile tool on the left, click the selected area, and then drag the map to the newly created layer;
6. Drag to the new layer as shown in the figure and finish the matting.
Photoshop's specialty lies in image processing, not graphic creation. Image processing is the editing and processing of existing bitmap images and the application of some special effects, with emphasis on image processing; Graphic creation software uses vector graphics to design graphics according to its own ideas.
Graphic design is the most widely used field of Photoshop. Whether it is a book cover, a poster or a poster, these graphic prints usually need Photoshop software to process the images.
The software can be divided into image editing, image synthesis, tone correction and functional color effect production. Image editing is the basis of image processing, which can perform various transformations on images, such as enlargement, reduction, rotation, tilt, mirror image and perspective. You can also copy, remove spots, repair and modify damaged images.

How to use ps for matting? PS matting method
First, the wand method-the most intuitive method
Scope of application: the color difference between the image and the background color is obvious, the background color is single, and the image boundary is clear.
Method intention: Get the image by deleting the background color.
Method defect: it is useless for messy hair.
Usage: 1, click the "magic wand" tool;
2, in the "magic wand" toolbar, in front of the "continuous" tick;
3. Fill in the value of "Tolerance" as "20". (The value can be adjusted according to the later effect);
4. Click the background color with the magic wand, and a virtual box will appear to surround the background color;
5. If you are not satisfied with the range of the virtual frame, you can press CTRL+D to cancel the virtual frame first, and then adjust the tolerance value of the previous step;
6. If you are satisfied with the scope of the virtual frame, please press the DELE key on the keyboard to delete the background color and get a separate image.
Second, the color model method-fast
Scope of application: the color difference between the image and the background color is obvious, the background color is single, and there is no background color in the image.
Method intention: crop the picture through the background color.
Method defect: not suitable for images with background color.
Usage: 1 Pick up the background color with a color straw;
2. Click the "Color Range" function in the "Select" function in the menu;
3. Tick the "Reverse" item, and select the image after confirmation.
Third, the magnetic lasso method-convenient, accurate and fast, is also my usual method.
Scope of application: the image boundary is clear.
Method Intention: The magnetic lasso will automatically identify the image boundary and automatically attach the image boundary.
Method defects: boundary points should be carefully placed on fuzzy boundaries.
Usage: 1 Right-click the Lasso tool and select the Magnetic Lasso tool;
2. Use the "Magnetic Lasso" tool to place boundary points along the image boundary, and a line will be automatically generated between the two points and attached to the image boundary.
3. Boundary points should be carefully placed on fuzzy boundaries.
4. After the cable sleeve is closed, the bedding is completed.
Four, (cable) feathering method-rough machining
Scope of application: Rough floor mat.
Method intention: rough digging, not seeking accuracy
Method defect: the image boundary is inaccurate.
Usage: 1 Click the Lasso tool;
2. Roughly enclose the image with lasso, and the distance between the boundary and the image boundary is almost the same; This can ensure the consistency of feathering range and improve the accuracy of matting;
3. Click the right mouse button and select the "Feather" function;
4. Adjust the feathering value, generally fill in "20", and then roughly select the image after confirmation. The feathering value should be adjusted according to the distance between the border and the image in the previous step.
Five, (cable sleeve) pen tool method-the most accurate and time-consuming method.
Scope of application: the image boundary is complex and discontinuous, and the processing accuracy is high.
Method intention: completely * manually place boundary points one by one for matting.
Method defect: slow. It takes about 15 minutes to dig a picture even if you dig your fingers and feet.
How to use:
The steps of the pen tool method are as follows:
1. The cable sleeve creates a rough path.
(1) Use the lasso tool to roughly outline the characters;
(2) Right-click "Create Work Path", and generally fill in "2" for the tolerance.
2. Fine-tune the path of the pen tool
(1) Select the pen tool and select the second "path" icon in the pen toolbar;
(2) Hold down the CTRL key, click each node (control point) with the mouse, and drag to change the position;
(3) Each node has two radian adjustment points, and adjusting the radian between the two nodes makes the straight line as close as possible to the edge of the graph, which is the key step of smoothing;
(4) Add nodes: If there are not enough nodes, you can loosen the CTRL key and add them on the path with the mouse. Delete node: If there are too many nodes, you can loosen the CTRL key and move to the node with the mouse. When the "-"symbol appears next to the mouse, click the node to delete it.
3. Right-click "Create Selection", and generally fill in "0" for feathering.
Press CTRL+C to copy the selection;
Create a new layer or file;
In the new layer, press CTRL+V to paste the selection, and that's it!
Deselect shortcut key: CTRL+D
Note: this tool is useless for messy hair.
Six, mask matting method-intuitive and fast
Usage: 1 Open photos and background images.
2. Click the move tool to drag the photo onto the background image.
Step 3 add a mask
4. Set the foreground color to black and select the brush 45.
5, so that you can wipe on the background until you are satisfied. If you wipe the wrong place, just change the foreground color to white and you can wipe it back.

First, the eraser pad
Methods, characteristics and scope of application: Eraser matting is to erase unused parts with eraser tools and leave useful parts. This method belongs to the shape matting method, which is simple and easy to use, but the processing effect is not good, and can be used for graphic matting with simple shapes and lines. But it is mainly used for further processing the effect of other methods after matting.
Operating steps:
1, open the picture;
2. Double-click the layer to change the background layer to a normal layer.
3. Select the eraser tool, and then select a brush with a larger main diameter. First, roughly erase most of the unused parts.
4. Select the small point of the main diameter of the brush, enlarge the picture and carry out fine processing.
Second, the magic wand cuts the map.
Methods, characteristics and scope of application: Magic wand matting is to use magic wand tool to select unused parts, or to select the parts to be used and then reverse them, and then delete them, leaving useful parts. This method belongs to the category of color matting, which is easy to use, but not suitable for achieving the expected effect. Therefore, it can only be used for matting when the color difference between the used part and the unused part of the picture is large, or as an auxiliary method of other matting methods.
Operating steps:
1, open the picture;
2. Double-click the layer to change the background layer to a normal layer;
3. Select the magic wand tool, and take an appropriate tolerance value in its attribute column (when the color difference is small, a smaller value must be selected, generally 20); If the graphic color difference is large, you can choose a larger value of 80;
4. Click on the background;
5. Edit/Clear
Third, the path is paved
Methods, characteristics and scope of application: Path matting is to circle the part to be used in the picture with pen tool, then load the path as the selection, reverse the selection, and then delete the unused part from the layer. This method is also a shape matting method, which can be used to matting pictures with complex shapes and small color difference. With the help of rubber polishing tools, good results can be achieved.
Operating steps:
1, open the picture;
2. Double-click the layer to change the background layer to a normal layer;
3. Select the pen tool and select parameters in its property bar;
4. Circle the parts to be used in the drawing;
5. The end point is connected with the starting point to form a closed area;
6. Click the Load Path as Selection button under the Paths panel;
7. Select/deselect.
Fourth, mask matting.
Methods, characteristics and scope of application: mask matting is a comprehensive matting method, which uses the shape and color of objects in the picture at the same time. First click the object with the magic wand tool, and then select the object with the Add Graphic Mask. The key link is to reduce and add the mask area repeatedly with a black and white brush, so as to select the object shape completely and carefully.
Operating steps:
1, open the picture;
2. Double-click the layer to change the background layer to a normal layer;
3. Select the magic wand tool with a large tolerance (50-80), press and hold the Shift key, and click to select all objects for many times;
4. Press the Add Mask Tool button;
5. Enlarge the display scale in the navigator panel and highlight the part to be modified;
6. Choose black as the background color and white as the foreground color;
7. Select a brush tool with a diameter of about 10, and add a mask area to the part to be modified;
8. Reduce the brush diameter (5-7), change the foreground color and background color, make the foreground color black, and subtract the redundant part;
9. If it is not ideal, repeat steps 7 and 8 to achieve satisfactory results.
Verb (abbreviation for verb) channel mask
Methods, characteristics and scope of application: Channel matting is a color matting method, which uses the flat contrast of objects in red, yellow and blue channels to process objects in high contrast channels. First, select the channel with high contrast, then copy the channel with further increased contrast, and then select the object with the magic wand tool. It can be applied to the matting of hair, branches, fireworks and other images with small color difference and complex appearance.
Operating steps:
1, open the picture;
2. Double-click the layer to change the background layer to a normal layer;
3. Open the channel panel and click on the red, yellow and blue monochrome panels to find out the clearest channel of the object. We click on the blue channel in this picture.
4. Drag the blue channel to the Create New Channel button under the Channels panel to copy the blue channel;

6. Mirror/adjust/reverse;
7. Circle fireworks and other patterns with lasso tools;
8. Select/deselect, edit/fill/fill the foreground color (white), select/deselect;
9. Mirror/Adjust/Reverse;
10, press and hold the "Ctrl" key, click the blue copy channel, load the selection of fireworks, switch to the layer panel, and the fireworks are selected;
1 1, select/deselect, edit/clear; Select/deselect
Of course, there are many professional skills, such as extracting foreground color and setting it to white, removing excess color with rubber, extracting hair and hair with contrast and sensitivity, and so on. But these methods are difficult to describe, so some space is omitted.
Discussion on PS matting skills in PS course
In many tourist attractions, there is a rapid synthesis of landscape photos to commemorate, that is, people are superimposed on fixed landscape photos, but the photos produced are relatively rigid. Photoshop darkroom makes it easy for us to make all kinds of synthetic photos, and thanks to the powerful function of Photoshop, you can completely confuse the real with the fake, so that you can "travel around the world" without leaving home.
The premise of making this kind of composite photos is perfect matting, which can be achieved by perfectly separating the composite object from the original background, and then using Photoshop's powerful filter function to do some light and shadow effects.
