Why are photos taken at night blurry when the photos taken at night are not clear?

You can use Photoshop image software to process the effect you want in 3 steps, first of all, you need to have Photoshop software installed on your computer.

1.The Ctrl+L command is often used to compensate for bias in image scanning input, which can give the image a rich sense of depth and sharp contrast. The specific usage is as follows:

Open an image file that needs to be adjusted, and then execute Image |[Adjustments]|[Gradation....] command to open the Levels dialog box (as shown in Figure 1-1-116).

In the dialog box, we can control the contrast between light and dark in the image by adjusting the "Input Levels" and "Output Levels", by dragging the triangle slider at the bottom of the dialog box with the mouse or directly entering the values in the parameter bar. For example, adjust the input color level to .45 and 160; The output color level remains the same, so that the contrast between light and dark of the color can be increased, so that the image can get the best effect, as shown in Figure 1-1-117.

2.Application of the Ctrl+M command for curves. In addition to the [Levels] command, the application of the [Curve] command is also very common, and its function is similar to the [Levels] command, but the biggest difference is that it can be used for more and more detailed settings.

In the dialog box, the abscissa and ordinate of the curve correspond to the "Input Levels" and "Output Levels" in the Levels command, respectively, and you can adjust the color effect of the image by changing the curved shape of the curve. When operating, we only need to move the mouse to the curve, then hold down the left button and drag to change the shape of the curve, after releasing the mouse, we can get a curve node, perform the above operation again to get another curve node, adjust the curve to the shape shown in Figure 1-1-119, so that the image can produce a strong contrast between light and dark, and get a glossy effect similar to metal reflection, 3【Hue Saturation】Ctrl+U The adjustment of image color is not only the adjustment of color contrast, but also the adjustment of image color attributes.

The Hue Saturation command can help us precisely control the hue, saturation, and luminosity parameters of an image, respectively. Execute Image |[Adjustments]|The Hue Saturation command opens the Hue Saturation Settings dialog box, as shown in Figure 1-1-120.

When adjusting, we usually check the "Colorize" checkbox in the lower right corner of the dialog box, so that the image can be adjusted to a single hue. Then we can drag and drop the triangle slider under the parameter item with the mouse or directly enter the value in the parameter bar. Figure 1-1-121 shows the effect of changing the original black and white ** to orange display.

You said that there are small dots.,It's in the dark environment to increase the ISO (sensitivity) more than 400,The noise that will be generated on the screen.,It's relatively simple to deal with this.,Use filters when PS (Photoshop online tutorials are quite a lot)->> Reduce noise.,And the lights on the phone are basically a decoration.。

As for the blur is a hard injury, it can only be slightly improved, PS increases the sharpness, and adds a high contrast to keep the layer to soft light, which will make ** feel clearer.

The next time you shoot in the dark, remember to find something to hold your hand, it will be better.

Or just find a bright spot.

This situation is normal, any brand and any model will more or less have such a problem, it is that the dust and water vapor in the air are directly entering the air of the lens, so this situation will occur, and the only way to avoid it is to change the angle or not to use the flash.

Also, shooting night scenes takes a long time, so if you don't use a fixed device (such as a tripod), it will shake and cause blur.

I won't know what to do with it, and I'm looking forward to the answers.

Bad results should be a matter of light, (you're not using a flash, are you?) You can adjust it with ps, but the effect will still be bad. Because it will save a lot of pixels.

It will not be clear. I guess you're going to have to re-shine. It is recommended to shoot with a digital camera, and if you can take photos in the daytime, the effect will be more ideal.

How many pixels does the phone have when shooting night scenes with a mobile phone? The best is limited! ps is useless, those coarse dots and blurs, the gods are difficult to save! It is recommended to shoot with a camera.

Extend** time with a tripod.

Poor lighting, resulting in excessive noise.

1. You can fix the camera to shoot (or try not to shake your hands);

2. You can also manually adjust the ISO parameters, the lower the image quality, the higher the image quality (some mobile phones support manual adjustment of parameters).

4. Be sure to avoid backlighting when taking pictures. It's best to shoot in the light.

Because the amount of light entering can be controlled by the shutter time, only one image is generated, and the lowest ISO can be used to shoot one with a very slow shutter speed. So the shooting is very delicate.

Summary. The hardware itself is responsible.

Since the clarity of the image has a lot to do with the camera parameters and the focal length of the lens, if the focal length of the lens is, the ccd is 1 3, then the viewing distance is more than 5 meters, so if it is beyond the range of your camera, the image is naturally not clear. In this case, the camera needs to be adjusted to the monitoring distance, and the best effect can only be achieved by adjusting it to its focal length.

The light source is not strong enough.

If it is clear during the day but not at night, the light source at night is not strong enough, which is also related to the minimum illumination of the camera. In this case, the only way to do this is to replace the camera or to enhance the lighting at night. If the camera is infrared, the camera can also add infrared lights to make up for the lack of light at night.

The bitrate is set low.

The camera does not have enough bandwidth to transmit high-quality images, and the bit rate needs to be increased. The method is to click on the video interface in turn: Configuration - Video Configuration - Video Parameters, if the single screen is blurry, it is recommended to adjust the upper limit of the bitrate of the main stream; If the small and medium-sized images are blurry in multiple screens, adjust the upper limit of the sub-stream.

There are three ways to deal with the above three reasons.

You can learn from it.

Hello, because seeing that you did not rate me last time, I am very concerned about your experience. If you are satisfied with my service, I hope you can give a thumbs up! If there is a problem, I am always waiting for you. I wish you a happy life and a happy life!

From the point of view of clarity, this night photo is a ...... without problemsVery clear.

It's a good idea to be able to take night photos with such an effect.

However, when you analyze this photograph from a photographic point of view, the situation is different......

First of all, the composition of this ** is not very ideal.

When shooting landscapes, it is generally composed in the rule of thirds. That is, the sky is one-third.

1. The ground accounts for one-third.

1. The subject scene accounted for one-third of the photographed.

This is even better.

However, the ** in question is clearly a ...... that is problematic in terms of compositionThe ground occupies too much, and there is only one corner of the sky left, and the overall effect is relatively poor.

In addition, it is the problem of **......

The overall effect of this ** is still okay......It's a good ...... for night shotsHowever, there are still shortcomings.

The bright parts of this **, that is, those bright light parts, are actually overexposed ......All formed a halo of ......This is a taboo state when shooting night scenes.

If you pay attention to the metering when shooting, and let the ** degree of those bright lights drop down a little, the overall effect of this ** will be even better......

1. When taking photos at night, choose the appropriate shutter speed and hold the camera very smoothly to achieve a clear shooting effect;

2. With a tripod, the picture in the lens will be fixed, so it will be more stable and the effect will be clearer;

3. Align the focal length, the appropriate focal length is one of the indispensable conditions for taking pictures, especially for night photography, the accuracy of the focal length is related to the clarity of the first grade;

4. Choose the right focusing environment and the light of your friends, preferably in a well-lit environment, so that the shooting effect will be clearer.
