Photography is shaky.

Lead: Many people don't make any settings after buying a camera, but just set the camera to be fully automatic, no matter what they shoot. In fact, if you have a certain understanding and research on the camera, you can prevent the shooting from failing. Let's get to know each other!

Virtual focus, hand jitter and subject jitter

First of all, when we don't shoot well, we should start with the failed photos. It can be clearly seen that the failed photos are basically due to virtual focus, hand shake and subject shake. You don't know how to shoot like this until you know the reason. So when shooting badly, don't just think it's a failure, but analyze the reasons for the failure.

Virtual focus refers to "the focus shift causes the portrait to be blurred". Generally speaking, the in-focus place will be shot clearly, the portrait will be sharp, and the out-of-focus place will be blurred.

Digital cameras often fail: the focus is on the background, but the person who wants to shoot is blurred. This is because when the shutter is pressed, the camera will automatically focus on the background, not closer to the main body of the camera. On the other hand, there are times when the focus is on nearby objects, such as trying to shoot a child sitting across the table, but the focus accidentally falls on the plate on the table. This is not good.

It is difficult to distinguish virtual focus on the LCD screen of digital camera. If you think there is something wrong with it, pay attention to it and shoot it seriously. Here are some tips.

(photos of virtual focus. What's the point? Just press the shutter of the digital camera. The shutter works in two stages. Half press, the camera begins to focus (that is, half press). Then press all the shutters and you can shoot.

In order to prevent virtual focus, it is best to press the shutter for half a turn to focus, and then press the shutter at a suitable time. Generally, digital cameras are looking for the object in the middle, so first put the child to be photographed in the middle to focus, and then move the camera slightly to decide the composition. Using this technology can prevent virtual focus to some extent.

It is difficult to get used to this skill, but it is easy to understand. I don't have to pay attention to such complicated things as half-pressing the shutter, focus according to my own wishes, and then take good photos. However, the camera is just a machine and can't understand your wishes. So users need to cooperate with the camera. This will make it easier to take photos with accurate focus.

In addition, there are cases where the focus distance is too close to cause virtual focus. Therefore, according to the type of aircraft, macro mode can be considered when shooting objects 50 cm away from the eyes.

Then there is the problem of jitter. The difference between virtual focus and jitter is very obvious. The whole outline is fuzzy and belongs to jitter. The background and foreground are very clear, and only the fuzzy subject belongs to virtual focus.

There are two kinds of shaking, one is hand shaking, because the hand is shaking when pressing the shutter, and the photos taken will be blurred.

In fact, even if there is hand shake, the photo will not be blurred because of the high shutter speed. However, when the shutter speed is 1/20 seconds, the hand shake in the photo is obvious.

In order to prevent hand shaking, we should first pay attention to the method of holding the camera. As I said last time, hold the camera tightly with your right hand, and then hold it with your left hand. It is best not to leave your body. If there is something nearby to support your body or elbow, you can put your elbow on the table. It is also possible to put your elbow close to your body without support. Then press the shutter gently.

If you always pay attention to hand shaking and be careful that the shooting still fails, then put your elbow on your knee or put your hand on a table or chair when shooting and relax yourself when shooting.
