Problems and solutions of photography

1. When the exposure is inconsistent, the metering mode of the camera may be set to spot metering.

This is the most common problem for beginners. Many times, we will hear the teacher say that in some cases, you will be guided to try the spot metering mode, and then many novice enthusiasts will regard spot metering as a general metering method. However, spot metering is not everything. When there are many strong light ratios, the exposure of many photos will be inconsistent, especially when moving the camera. Then when you look at the photos on the monitor, you will find that the brightness of many photos is very different. So be sure to check the metering mode at this time. It is very likely that you used spot metering. At this time, you can try to switch to average metering, which may solve this problem.

2. Sometimes you may encounter dirty spots on multiple pictures, and feel that the photos taken are all dust.

This requires you to establish a thinking order. First, you can see if there is dust in the front lens of the lens, and then check whether there is a problem with the sensor inside the fuselage. If there is no problem with both, I suggest you check the components inside the lens. If there are mildew spots inside the lens, it may be troublesome and you may need to find a professional to clean it. Never do it yourself. Here is a tip for you to check whether there is dust in CMOS. You can use a small aperture such as f/ 16. At this time, the photos taken will be particularly obvious if there is dust. If you shoot against the sky or in a solid color, such as a pure black and white environment, the dust display will be more prominent.

3. The manual focusing mode that the master likes may not be completely suitable for you.

Don't believe those who always talk about manual focusing mode, which will only lead you astray in some cases; If you find the following situation, that is, shooting with the shutter half pressed, but the camera doesn't start focusing at all, and the motor in the lens doesn't rotate, then you probably set the camera or lens to manual mode. The first idea you need to develop here is to check whether the manual mode of the lens is turned on first. Therefore, it is suggested that you should decide whether to set the focus mode to single focus mode, continuous focus mode or autofocus mode according to the subject.

4. The shooting driving mode can be set to delay self-shooting.

I have met some new photographers before, and when I found a very good scene or opportunity, I raised my hand to grab the camera. As a result, they found that after pressing the shutter, the camera was dripping, that is, the shutter was not started. It won't start for a few seconds. This means that you may not be able to return to the initial value after using the self-timer delay before, so it is recommended that you switch the camera driving mode back to single shot or continuous shooting mode when shooting every activity. Otherwise, you are likely to miss the next shooting moment, because after pressing the shutter, the camera will only start counting seconds, and will not release the shutter immediately. Then you missed a good opportunity to shoot and make a blockbuster.

5. The setting of 5.ISO value is unreasonable, and the field environment has not been measured and predicted.

When we lack photography experience, it is very likely that the ISO value will be set too high or too low. Especially when we shoot in low light, we often subconsciously raise the ISO value, but it is common for some film friends to forget to adjust it back. On the surface, this is not a serious mistake, but it may damage the quality of your image. If you use automatic shooting, the camera will automatically balance other corresponding parameters under certain conditions, and at the same time, when shooting in bright environment, it will limit your shutter speed or aperture range. This will make you unable to achieve the expected results when shooting.

Therefore, on some photography topics, Bian Xiao will often say this to many movie friends who are studying. Before pressing the shutter, we should make a method to check whether the parameter relationship between the photographic elements inside the camera is in a normal state at any time. If you don't check and change the environment, it is very likely that your photos will be very dark, too bright, or the picture quality will be a little poor because of the automatic file. This is very important, even old photographers who have been playing for many years will find these problems.

6. The memory card is unformatted. Before formatting, make sure that the last negative has been backed up.

This is a mistake that always makes people impatient or funny. Many friends who play photography do not have this habit. They will put photos taken from several scenes together and don't form this habit. Then in the following shooting activities, they will find that their memory card suddenly prompts that there is no space or insufficient space, and then your shooting has to stop halfway. Then there will be a scene where you grope for the camera and delete photos one by one. Models or others have been taking pictures in full swing.

Even more frightening is that some people will forget to bring their memory cards. Bian Xiao met many times. When taking photos outdoors, a friend arrived at the scene and found that he had forgotten to bring his memory card. Embarrassed ~!

Therefore, we must develop good habits, export photos immediately after shooting, and check whether the camera accessories and memory cards are normal and installed in the camera before going out. After confirming the photo transmission and backup, format the memory card and prepare for the next shooting.

Backlight shooting glare is not only because of the light, but also because your camera needs to be cleared.

Anyone who has played photography may encounter such problems. In the process of shooting, it is occasionally found that some photos will have glare. There are many reasons for glare, but it will definitely reduce the overall contrast of the picture, or form bright spots in the picture and interfere with the picture. If this situation is too serious, it will be irreversible in the later stage.
