How can I take a picture to be particularly clear?

A good photo needs to be taken clearly in addition to accurate exposure, reasonable color matching and composition. Most of the reasons for blurred photos are camera shake, depth of scene, focusing error and so on. So if you want to take a clear picture, you need to do a good job of anti-shake, increase the depth of field, focus correctly and so on.

1, write first, then focus.

Many people will like to use the focus composition method of "focus first, then composition". Although it is easy to use, it is very likely that there will be errors in focusing. In addition, when using autofocus, when the picture contrast is small, there are obstacles and the shooting distance is too close. There is also a great possibility that autofocus will not appear, which will lead to the problem that the subject of the photo is not clear.

Therefore, in the process of shooting, if time permits, it is recommended to make a composition first, and then adjust the position of the focus to focus. If you can't focus, you can use manual focusing to complete the focusing operation, and generally you can take clearer photos.

2. It would be better to reduce the aperture by one gear appropriately.

When the depth of field is shallow, moving the focus slightly may lead to inaccurate focus and make the photos easier to blur, such as shooting macro works. Therefore, the solution to the depth of this scene is to increase the depth of field.

To increase the depth of field, we often use the method of reducing the aperture. How much aperture should we reduce? Personally, I think it is best to reduce the aperture of 1. Generally speaking, the maximum aperture of a camera is reduced by 1~2 to get the best image quality. When we take a picture with a larger aperture and then reduce it by 1 step, the focus will not be slightly affected, and we can get a clearer picture. Generally, the aperture is set in the range of F5.6~F 1 1.

Of course, you can also choose a smaller focal length (wide-angle end) or increase the shooting distance appropriately to get a larger depth of field and get a clearer picture.

3. Avoid shaking hands and pay attention to the safety shutter.

When we shoot hand in hand, our bodies will shake slightly. When the shutter speed is slightly slow, the photos may shake and blur, so we need to pay attention to the shutter speed of the camera to improve the possibility of avoiding shaking and blurring. Generally speaking:

Safety shutter = 1/ equivalent focal length

For example, if we shoot with a 50mm lens of a full-frame camera, the shutter speed should generally not be slower than 1/50 seconds, so as to take a relatively clear photo. Of course, some photographers can use 1/30 seconds properly because their cameras are relatively stable.

Of course, the best choice is to increase the shutter speed, so as not to be afraid of motion blur caused by hand shaking.

4, slow door shooting should pay attention to anti-shake

When shooting the slow door theme, the blur problem is most likely to occur. Our general anti-shake measures are as follows:

① Use tripod and cable to release and turn off the anti-shake function of the lens;

② Pre-lift the reflector, or use the display screen to display the shooting situation in real time;

(3) when there is no tripod line release, you can switch to the delayed self-timer function.
