The photos taken by SLR cameras are blurred in a few points. What happened?

1, the focus is not accurate, but the manual focus is forgotten, and the automatic focus is wrong.

2. The shutter speed is too low.

3. The camera can't focus on the target below the nearest shooting distance of the lens.

4, iso is too high, and the picture is grainy.

solution

First, focus priority: a major reason for blurred photos is that the shooting is not focused, or the focus object is wrong. You can check whether the focal length is locked on the correct subject before pressing the shutter. Don't press the shutter directly. You should press the shutter half first to focus, and then press the shutter to finish shooting.

Second, use a tripod: a tripod is an ideal tool to avoid shaking the fuselage. When shooting with a tripod, there is no need to worry about the shutter speed (the slower the shutter speed, the higher the possibility of blurring), and at the same time, ISO can be minimized to avoid too much noise in the picture.

Third, reasonably adjust the ISO: The ISO setting of the camera is very important, because it allows you to get a higher shutter speed. For example, if ISO is adjusted from 100 to 200, the shutter speed can be shortened from 1/60 seconds to1/25 seconds, which is enough to avoid camera shake and blur caused by subject movement.

Fourth, looking for light: when shooting, we should also try to create a bright shooting environment. For example, when shooting people, you can make the subject feel closer to the light source. If the light is sufficient, the shutter speed can be further shortened to avoid blurring the picture.
