How to show beautiful and tall photos?

1. Prevent vibration. Vibration will blur the image in the photo, even if the focus is very accurate, it will affect the clarity of the image.

There are generally two reasons for vibration: First, the camera vibrates, that is, when the shutter is pressed, the camera shakes due to unstable grip. The second is the motion of the subject, that is, at the moment when the lens shutter is opened, the subject is in motion, and the shutter time is not short enough to freeze the motion, so the image is blurred. To prevent vibration, we must suit the remedy to the case and take measures from three aspects:

(1) Mount the camera on a tripod. If the tripod cannot be supported due to shooting conditions, a monopod can also be used.

(2) Shortening the shutter time (generally 1/250 seconds) can reduce the image jitter caused by camera vibration.

(3) adopt the correct way of holding. Without a tripod, the correct posture of the camera will directly affect the stability of the camera. There is only one way to overcome the subject dynamic blur, and that is to shorten the shutter time. As long as conditions permit, the shorter the shutter time, the better the effect.

2. Don't pursue small aperture unilaterally. Beginners think that a small aperture will increase the depth of field and will definitely make the image clear. Therefore, they often turn off the aperture very small regardless of the occasion, especially when they are not sure about focusing, they will believe that a small aperture can help them. But the final effect is often not ideal, because the use of small aperture will lead to the extension of shutter time, so camera vibration will have enough negative effects. Therefore, it is not the best policy to pursue a small aperture unilaterally. The correct way is to use a short shutter and tripod.

3. Correctly understand the characteristics of the lens. Many people think that the smaller the aperture of the lens, the greater the definition of the image. This view is incorrect. In fact, the best state of lens imaging is to reduce its maximum aperture by 2-3 steps. For example, a lens with a maximum aperture of F2.8 has the best imaging effect when its aperture is close to F5.6-F8.

4. Pay attention to the relationship between background and subject. The color contrast between the subject and the background will affect people's vision. In the case of constant focus, the contrast between the subject and the background is large, and the image looks clear. If the color contrast is small, the image looks low definition. Therefore, in order to make the subject appear particularly clear in the picture, it is very effective to choose Gao Fancha as the background consciously.
