How to solve the fuzzy state of SLR camera shooting?

The main reason of unit camera blur is hand shake. To avoid this situation, we should adopt the wrong shooting posture, choose a slower shutter speed, change the focal length of the lens and shoot in a "telescope" state.

First, the correct posture of the SLR camera:

1, basic holding method

Hold the camera handle with your right hand and the bottom of the camera lens with your left hand. When using the zoom lens, the left hand can easily turn the zoom ring on the lens to zoom. Novices often hold the camera on both sides with both hands, which is easy to shake and is an incorrect posture.

2. How to use the viewfinder

Using viewfinder to shoot, you can clearly observe the viewfinder image and set parameters in the display, which is the most basic shooting method. When framing, the eyes should be parallel to the electronic viewfinder of the camera and as close as possible to the framing window to get the best view. At the same time, the face is close to the lens, which makes the camera more stable.

3, shooting posture-standing posture

The basic point is to clamp the upper arm. Pay attention to the overall posture here. When we bow our backs, we will unconsciously relax our arms, leading to "hand shaking." When shooting while standing, imagine yourself as a tripod with your feet shoulder-width apart to provide stable support.

4. shooting positions-squatting posture

When taking a full-length photo of a character, you will get a better body proportion when shooting from a lower angle. At this time, we knelt on the ground and filmed. The posture of landing on the right knee and supporting the left elbow on the left knee can make long-term shooting more stable.

5, shooting posture-vertical composition

When shooting a vertical composition, rotate the camera 90 degrees. The camera handle can be up or down. The upward posture of the handle is more convenient to move; The downward posture of the handle can clamp the upper arm, which is more stable.

6, shooting posture-practical real-time display shooting

Novices who are used to the card machine are used to watching the camera screen, which is easy to cause "hand shake". When shooting, make your arms bend at a 45-degree angle and your upper arms cling to your chest, which can provide some support and make the shooting more stable.

Second, the photo is blurred due to the shutter speed.

When shooting the same target, increasing the shutter speed is not easy to cause hand jitter, but if the shutter speed is reduced, the probability of hand jitter will increase.

Above, F3F3.22,1/8seconds, ISO100,0ev, the shutter speed is slow, so there is a hand shock.

Above, F2.8,1/60s, ISO 800,0EV, fast shutter speed, no hand shock.

Third, the focal length of the lens causes the photo to blur.

1. After mounting the lens, set the focal length to 18mm.

2. If you take photos indoors, the shutter speed will generally be115 ~1/30 seconds. Therefore, if you take a picture at a wide angle and the focal length is 18mm, you can take a clear picture without shaking hands.

3. Turn the zoom ring and set the focal length to 55 mm for shooting.

4. When the focal length is 55mm and the shutter speed is the same as that at the wide-angle end (18mm focal length), hand shake will occur when using telephoto lens.

5. Comparing the two, we can find that there is no hand tremor when using wide-angle lens, but it appears after shooting in telephoto state.
