Why are the photos taken by DSLR a bit blurry?

Inaccurate focus

When we take a photo of a subject, the judgment of the focus position also affects whether the photo is clear or not.

Don’t blindly pursue the maximum aperture when shooting. You still have to narrow the aperture appropriately according to your subject. (The smaller the aperture, the greater the depth of field), so in the above case, narrowing the aperture can get a greater depth of field, and the clear range will be larger.

The shutter speed is not fast enough

When it is lower than the safe shutter speed, it is easy to blur the picture due to shake if you shoot handheld. Therefore, a tripod must be used when conditions permit. If you don't have a tripod, you'll need to adjust to a faster shutter speed. We can feel it through the following two comparison pictures. In the same environment, using the 55mm focal length, the same ISO and aperture, the only difference is the shutter speed, and the effect of shooting in a handheld situation.

Camera shake

Camera shake is the most common cause. Many people think that the camera is held very stably, so even if the photo is blurry, they may not think that it is camera shake. caused.

In fact, there is a reason for us to reflect on it from a more subtle perspective. First, ask yourself whether the posture of holding the camera is correct.

Let’s talk about standing first. In order to stand more firmly, our legs should be slightly apart.

In addition, some novices are accustomed to holding the camera with both hands from both sides. In fact, they should hold it with one hand under the camera body.

As mentioned before, slow shutter speed will cause the picture to be blurry. Sometimes the situation requires you to shoot with a slow shutter speed, and there is no supporting tripod or other situations. At this time, in addition to being very stable, you need to While holding the camera, even the rhythm of breathing must be controlled, light and slow.

The other is the most basic step: press the shutter halfway. Many entry-level users are eager to think about how to shoot blockbusters after buying a camera. They often click and snap when they see something they like, but they neglect to pay attention to the most basic operation. Speaking of half-pressing the shutter, there is an operation key that needs to be paid attention to. Use the pad of your index finger to press gently.

The subject moves

Sudden situations such as the subject moving are often encountered. For example, when shooting flowers, the focus is already in focus, and suddenly there is a scratch. The wind makes the subject sway, so you need to adjust the shutter speed or wait for the subject to stop before refocusing. ?
