First, the use of software: Photoshop
Second, the method steps:
1, first open the picture to be processed with photoshop. Copy the background layer to get a "background copy".
2. Switch to the channel panel, select a channel with the largest color contrast between people and background, and copy it to get a "green copy".
3.Ctrl+L adjusts the color level of the "green copy" layer to increase the contrast between human hair and background.
4. Press the "Green Copy" layer while holding down the ctrl key to get the selected area as shown in the figure. Then press the shortcut key shift+ctrl+I to reverse the selection.
5. Switch to layer mode, press ctrl+C to copy the selection, and then press ctrl+V to paste the selection layer to get the hair layer as shown in the figure.
6. Close the small eye hidden layer of the hair layer, and then use the pen tool to dig out the outline of the character.
7. As above, ctrl+C copies the selection layer, and ctrl+V pastes the selection layer.
8. Open the two excavated layers. Preview it in different backgrounds!
Question 2: How does PS choose the avatar of the character? In PS, there are many methods of matting, such as simply using magic wand and background eraser, and if it is higher, using pen tool to draw a filter. If these are not enough, we can consider using mask and channel method to deal with them. Just dig out the part you need, and then drag it directly to another picture with a mobile tool to determine the position and size.
In addition, of course, there are still some things to pay attention to when doing image synthesis. For example, after two pictures are combined, factors such as color and light intensity need to be considered. Only when these things are done can it be complete.
PS: If you don't understand anything, please keep asking ~ ~
Question 3: How to use ps 1 to dig people? Wand DD is the most intuitive method.
Scope of application: the difference between image and background 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 DD is fast
Scope of application: The difference between the image and the background 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 DD is convenient, accurate and fast, and it 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 attach it to 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 sleeve) feathering DD 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.
Verb (abbreviation of verb) (cable sleeve) The most accurate and time-consuming method of pen tool DD
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 a "D" 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.
Sixth, the mask matting method DD is 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. ......& gt& gt
Question 4: How to save ps matting? I only need to save the matting in gif format, and the picture quality will be lost, because gif only supports 256 colors. You can save it in Pang format, so that the picture is clear and transparent, and it may take up more space than gif. If you want to use it next time, save it in psd format. Hope to adopt
Question 5: How to use photoshop to dig out the characters in the photo? 1. If the color difference between the person and the background in the photo is relatively large, you can use: filter-extraction method for good matting. 2. The person in the photo is very close to the background object, which is very fuzzy. Available: magnetic lasso tool. 3. The character edges are neat and the background color difference is large. Can be used: magic wand tool. 4. If the hair is flying around, it needs to be handled with a "channel". Dig out the picture in one of the above ways. Two. Create a new file background layer. 1. If it is a white background, please note that the pixel size should be the same as that of the photo you are matting. 2. If you choose a landscape photo as the background, the pixels should be as good as your cut photo, otherwise the definition of the composite photo will not be uniform. 3. After processing the background layer, use the Move Tool to move the cut characters to the background layer. Then you can use the Smudge Tool to clean the edges of the characters. If the background layer is not white, you can use the gradient tool or the paint bucket tool to add color to it. 4. Before merging the layers, you need to see if there is any problem with the brightness and color difference of the people or background layers. If they are inconsistent, you can adjust the Brightness/Contrast to compensate for the color difference. 5. Layer-Merge Image-Save (name, format) OK.
Question 6: How does 6:PS dig out the characters in the picture and stick them on another picture with a pen? The contrast of this picture is not strong, and other fixtures are not effective. If the requirements are not strict, just use an eraser and wipe off the excess. (Select Fuzzy Eraser)
Question 7: How to dig out the outline of characters with ps? photoshop matting is not studied in the background these days. Personally, all matting methods are nothing more than two types: one is to make selective matting; The second is to use a filter to cut the picture. The slightly difficult matting in figure 1 is "picking a wedding dress", which means picking tiny objects, such as hair; Choosing a wedding dress means choosing transparent objects, such as wedding dresses and glasses. Ok, let's analyze photoshop matting in three categories: first, one-step matting DD, the most primitive and least technical matting method. 1, double-click the gray * * * field in the photoshop window to open two material pictures. Figure 22. Move the picture to the desired background picture and change the mode of the layer to "color filter". Figure 33. To sum up, the picture with black background uses "color filtering" mode; The picture with white background is in "Front Overlay" mode. Of course, if the object you want to dig is black or white, that's another matter. Figure 44. This method doesn't seem to be very useful for pictures with white background. So we use another simpler method DD magic wand tool. The main purpose of listing here is to let you know that there is such a method to correspond to pictures with black background. If necessary, add or subtract the selection area, and sometimes it needs to be reversed; Explain, Shift+ tool, add selection; Alt+ tool, reduce the choice; Ctrl+Shift+I, reverse selection. Figure 55. Final effect drawing: In addition to magic wand tool, lasso tool and pen tool are also good choices in Figure 6, but it is best to use magnetic lasso tool and pen tool, which will not be described here. In addition, in the PSCS3 version, there is a "QuickSelectionTool" that is more powerful than the magic wand tool. You don't need any shortcut keys to add and select areas. Long press can select areas like drawing, which is amazing. Of course, there are three modes to choose from in the Options Bar: New, Plus and Minus. It will be very intuitive and quick to quickly select pictures with large chromatic aberration. If it works, you can try CS3. If you want to know more, I will give you an online matting tutorial. I believe you can find the one that suits you! 1.pconline/pcedu/specialtopic/pskoutu/You said you didn't want the background, just look at this.
Please accept it, thank you!
Question 8: How to dig people with ps Simple method 1: Dig a picture along the edge of people with magnetic lasso tool;
Method 2: follow the path of figure painting with a pen and transform it into a constituency after painting;
Method 3: If the background color is not much, directly use the magic wand to select the background color, and then reverse the selection.
Question 9: How to cut the picture with PS? How to combine it with another picture after digging it out? There are many ways of matting.
For example, a simple lasso wand can be used to cut channels.
Foreweb/Article/Special/pskt/ You can visit this website. Very good. There are various methods.
Just copy your deducted picture to another picture.
Copying the past can be enlarged and reduced in the new coating = =
Question10: the best method of PS matting (clipping people) Channel matting.
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;
5, image/adjustment/color scale, adjust the "input color scale" to enhance the contrast of the object;
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
How does ps dig people? 1. How to dig people with PS?
figure
Using the Polygon Lasso Tool, select the feathering value as 1 (so that the edges will not look too stiff).
Then circle the characters you want bit by bit,
After that, you can open the background you want to change and copy the people you just selected into the new picture.
You can also use the lasso to select characters, click Select-Deselect, DEL, delete the original background, and then paste the new background. Just put the new background under the people layer and the people will be on the background map.
hair
To cut the hair at the bottom of the positive stack:
1. Use magic wand to dot most areas (use layer mask).
2. Copy a layer and hide the newly copied layer.
3. On the original layer, ctrl+l, point the white straw, absorb the part that has not been removed from the mask (that is, the main part of the character), turn the photo into black and white (image _ adjustment _ color removal), and change the mode of this layer to positive superposition.
Click on the hidden copy layer and fill the edge of the hair with gray.
4. Finally, just slightly adjust the color of the following layers.
In fact, each haircut method is different, and the effect is not too bad. Each picture has a more convenient clipping method, depending on how you choose. I tried the channel editing you mentioned and found it quite complicated. There is also an extracted method of cutting and pasting, which I think is ok ~ So, learn more methods, which will definitely be used in the future!
The hope of copying is useful to you.
Second, ps matting as long as the characters don't want the background.
Photoshop must use all formats (ctrl+alt+shift+s) saved as the web to make transparent background pictures. You can also use his ImageRadyle, which is saved in web format (all formats are stored on it). It is important that the format is a transparent background without a transparent background, whether it is format or format PS. Simple icon mask (transparent background picture). 1- Open a picture in PNG format in Photoshop 2- Set the foreground color to black 3- Press Alt)+(Shift)+ (Backspace) to color existing pixels (black) 4- Select a layer >; Flat image 5-Press Ctrl+(i) to reverse the image color, and save the image in BMP format to make the icon edge look smoother (without white edges) (transparent background image) 1- Open the image in PNG format in Photoshop 2- Select layer (coating) > DuplicateLayer 3- Select the bottom layer 4- Select filter >; Other > Minimum 5- Change the radius to 1 How to use Photoshop to output pictures in PNG format with transparent information? Here are the operating steps: 1. Open the picture to be processed (in any format) and resize it first. Although this has nothing to do with the transparent background picture, if the picture is too large, it will affect the browsing speed. Who wants to see only one photo? Therefore, under the condition of not affecting the visual effect, try to reduce the image as much as possible, and the length and width of the image should be basically the same as its size in the web page, otherwise the image will be deformed after insertion.
You can use the Image Size command in the Image menu to adjust the size. 2. Select the required parts with lasso tool. This step is to separate the desired image from the opaque background of the original image.
PhotoShop5.0 version 5.0 and above added the magnetic lasso tool. This tool is very convenient for selecting the part with big contrast with the background color, but it also needs some patience to select the required image completely. Then use the Copy command in the Edit menu item to copy the selection to the clipboard.
3. Use the "New" command in the "File" menu to create a new image. The dimension uses the default value in the dialog box, that is, the minimum value given by the system according to the data in the clipboard.
In the "Content" column, you must select the "transparent" item, which is the key to generating a transparent background image. After clicking "OK", if there is no accident, you will see a new image with a grid. In fact, it is a blank image with a transparent background.
4. Use the Paste command in the Edit menu to paste the contents of the clipboard into the new image, and select the move tool in the left toolbar to move the image to the appropriate position. At this point, the basic operation has been completed. Remember never to merge layers here, otherwise the previous work will be in vain.
5. Finally, choose the "Save as Backup" command in the "File" menu to save the file, and select *. Format in the "Save As" selection box, and click "OK" to enter the next step. 6. In the next dialog box, you should also select Transparency, use the default values for other items, and then click OK to finish.
Now, a perfect transparent background image is ready! Try it quickly and insert it into the webpage for a preview! How's it going? Perfect, right? Another kind of friend who is skilled in photoshop: convert the image into IndexColor, select the part to be transparent, make a channel, and save the file directly in GIF format with the channel, OK. Method 2 1. Start Photoshop and open the required picture file. At this time, we can see a layer named "background" in the layer panel, because in Photoshop, the background layer is not allowed to be edited directly, so we need to convert it into a normal layer.
Double-click the layer and the New Layer dialog box will appear. Click [OK] directly to convert the "background" layer into a normal layer. Next, select the magic wand tool in the tool panel, click the background color to be deleted, and then press the "Delete" key to delete the background color completely. The grid part in the figure indicates that it is transparent.
Finally, we output it as a file in PNG format, click "File/Save as Web Format", select "PNG-24" format in the save option on the right, select the "transparent area" option below, and click [OK] to save. In fact, exporting to GIF is also possible. If the image quality is not high, it can be previewed well, but the preview of PNG is not so good. 2. It's easy to do. When you create a new picture, remember to tick the background as transparent, confirm it, remove the unwanted colors and save it in a format. In ps, make a transparent picture with no background color, then select "Save as web Format" and select GIF (in it.
You get the transparent picture you want. If you don't choose the "Save as web Format" mode, the transparent background layer you made will be replaced by the background color.
Third, the detailed steps of ps matting
Using software: After PhotoShop matting is used in PSCC version, the steps to separate the matting part separately are as follows.
(Take the pen tool as an example here): 1, put ordinary photos into PS software; 2. Use the pen tool to dig out the characters in the photo; 3. After the pen matting is completed, press Ctrl+Enter to change the path into the selection area; 4.Ctrl+J copies the contents of the selection, that is, the cut-out character part, and turns off the display of the background layer; 5. The picture in "File-Save As" format is complete. Note: There are many methods of matting in PS, such as magic wand matting, polygonal lasso matting, pen matting, channel matting and filter matting. According to the different characteristics of pictures, choose the appropriate methods and tools.
Fourth, how to deduct the characters in Photoshop?
1. Open landscape pictures and people pictures with Photoshop.
2. Switch to the figure picture and select the background part with the magic wand tool.
3. Press Shift+Ctrl+I to reverse the selection and select the person.
4. Use the mobile tool to drag the character onto the landscape map and adjust the position.
5. Change the opacity to 50% to make the characters translucent.
6. Save the picture and customize the path, name and type.
7. The picture has been saved.
How to dig people out by matting 1 If the color difference between the person and the background in the photo is large, you can use the filter-extraction method to make a good matting.
2. The person in the photo is very close to the background object, which is very fuzzy. Available: magnetic lasso tool.
3. The character edges are neat and the background color difference is large. Can be used: magic wand tool.
4. If the hair is flying around, it needs to be handled with a "channel". Dig out the picture in one of the above ways.
Two. Create a new file background layer.
1. If it is a white background, please note that the pixel size should be the same as that of the photo you are matting.
2. If you choose a landscape photo as the background, the pixels should be as good as those of your cut photo, otherwise the definition of the composite photo will not be uniform.
3. After processing the background layer, use the Move Tool to move the cut characters to the background layer. Then you can use the Smudge Tool to clean the edges of the characters. If the background layer is not white, you can use the gradient tool or the paint bucket tool to add color to it.
4. Before merging the layers, you need to see if there is any problem with the brightness and color difference of the people or background layers. If not, you can adjust the brightness/contrast and color difference respectively.
5. Layer-Merge Image-Save (name, format) OK.
