How to take photos of test papers with mobile phones?

1. Make sure that the mobile phone is parallel to the center of the test paper when shooting the test paper.

2. The shooting environment ensures sufficient light.

3. Try to keep the phone stable when shooting, and don't shake it.

4. After taking a photo, you can edit the photo through the mobile phone photo album and adjust the brightness, contrast, sharpness and other parameters to achieve the final ideal effect.

5. You can use third-party software to shoot documents, such as Universal Scanning King.

First of all, we print on the computer, so I am in favor of using some software or small programs on the mobile phone. After all, mobile phones are difficult to operate or export.

I also often print some sports photos for my children. Perhaps due to light, angle, cell phone pixels and other reasons, many photos are not very good, some are not straight, and some are printed in black even if they can be seen.

In view of this, I tried a variety of software, and finally found a good picture processing software, which is very suitable for parents without any foundation. In terms of function, we mainly use three points:

Some photos taken are not correct. If you don't adjust it, the printed one will be tilted, which will affect the children's homework to some extent.

Open the software and load the photos from the mobile phone into the computer.

Click "rotate"

The Rotation operation interface appears.

The corresponding 1234⑤ here are:

① Free angle rotation; ② Rotate 90 to the left; ③ Rotate 90 to the right; 4 flip up and down; ⑤ Left and right mirror images flip.

According to the angle of the picture, you can first use the mouse ② ③ to adjust it, and then use → and ← on the keyboard ① to rotate freely and fine-tune the angle until the angle is positive.

Sometimes the photos taken will have some messy black edges. At this time, the clipping function is needed. Click the Crop button in the upper right corner.

Enter the cutting interface and adjust the cutting size.

This is also the most critical point of our theme. Click "Edit" in the upper left corner of the software interface.

In "Popular Style" on the right, select "Style Special Effect"-"Sketch Effect".

Let's compare it.

The effect is very good.

PS: Regarding the function of "setting transparent color" in the image processing function of WPS word processing software, there will be some slight uncertainty when processing the background color of the image, and sometimes the processing effect is not good, so it is not recommended here.

You can use WPS image processing tools.

Click on the picture, click on the button in the toolbar above, deduct the setting transparent color in the background, and then use the mouse to move to the picture and click.

Scan Almighty King with mobile phone CS, everything will be processed automatically, good and fast, and you can share it. This is the goods.

With the first app, members can spend more than ten yuan at a time, but it is very easy to use, better than Almighty King, and can trim the edges. I've used it for many years. I use it on Apple phones, but I don't know if Android is available.

Taking pictures is not recommended, but it can be scanned. This function is included in the memo of Apple's mobile phone. Other mobile phones are not clear, if not, you can download the software.

The main thing is to do some articles in shooting, otherwise it will easily lead to blurred or dim photos, so the printed things are also gray. Recently, I often give papers to children, and I also take them with my mobile phone. I can share my experience briefly.

The paper is black and white, so it doesn't need to be processed in the case of good brightness. It can be printed directly after shooting. Pay attention to the following two points when taking pictures:

1. brightness: this is the most important. If the light is dim, the video taken by the mobile phone must be gray. First of all, we must ensure that the brightness of the shooting environment is sufficient. If you are shooting indoors, you'd better turn on all the lights. Pay attention to let the subject shine, and avoid backlight shooting. You can set many options when taking pictures, such as exposure, saturation and so on.

2. Stability: First, pay attention to holding the mobile phone steadily, preferably with your hands and arms resting on your body, supported by tables, chairs and walls. The second is to stand firm. It's best not to shoot while walking. You should know that the stability of the picture is the first element of dynamic shooting.

The most important thing here is to clean up some minor problems in shooting.

Color scale: you can adjust the exposure of the shooting picture, and you can adjust the exposure too high or too low.

Curve: black and white can be more prominent here. Because of the color of the paper, there will be a gray background when printing, and it can be turned into pure white here, which will not affect the printing effect.

Contrast: Appropriate adjustment can fine-tune the brightness problem, which is slightly different from the function of curve, so it is best to use it together.

If you want to print clearly, you still need to do some operations, mainly taking pictures, supplemented by adjustment. This can effectively improve the clarity of printing paper.

At present, many parents have this problem to some extent

First, environmental reasons, photo environment, too dark or too bright light will lead to poor display of the pictures taken. When printing, in the preview state, you can drag the mouse wheel to enlarge the photo, see the font enlargement, and see if the enlarged text is clear. If the font on the computer monitor becomes blurred, there is no need to print. If it is dark, it means that the picture has a shadow. If you use useful software to beautify, such as ps and other graphic tools, the premise is that you have a little art foundation. If you don't have this level, take more high-quality photos and choose slow printing. There is no way, stupid way is feasible.

I can try not to take pictures. Electronic documents that are not printed clearly. I am a graphic worker. The poor original picture is really annoying.

If you have the conditions at home, the printer has a copy function, so you can copy it, or you can scan it first and then print it, which is better than taking pictures and then printing. The effect of printing and scanning is much better than that of taking pictures with our mobile phones alone. Compared with us, we are not professional photographers.

Ps: PS You can use the shortcut key Ctrl+M to adjust the graphics. It is enough to reach your own naked eye feeling and reach the expected state. Online classes are very hard, I hope students will work hard!

Mobile phone shooting files will be very dark and blurred due to light and other problems, and can be processed by ps.

1. Select the perspective cutting tool, click on four corners, and press Enter to straighten automatically.

2. Remove the color of the picture, call up the color code, point the text with a black straw, and point the background with a white straw, and it will become clear.

3. Copy a layer, keep the Gao Fancha in the filter, and change the blending mode to linear light, which will be clearer.

Remember to collect [flash] what you find useful.

It's simple [yi tooth]

Attention! Make sure there is enough light when taking pictures!

Then, use the mobile phone mito software to modify.

Increase brightness exposure and adjust contrast. Try these.

Adjust the powder concentration of the printer again when printing! For example, it is -0- so now adjust it to -2 and try to print it out. It should be whiter. Finally, if you are not satisfied, just put the example you just printed in and copy it. The effect will be different!

Of course, it is not excluded that the printer toner cartridge or the toner just installed in the printer can easily lead to black printing paper!
