How to take clear photos with SLR?

It should be noted that we should pay attention to:

1. Focus

For real focusing, pay attention to focusing on the subject you are shooting. Focus by half pressing the shutter. If the focus is successful, the camera will have a focus prompt tone, and then press the shutter to shoot. After focusing, you cannot move the camera back and forth. You can only rotate left and right, and translate the camera model to re-compose.

2. Depth of field

That is, the clear range, often seen photos with blurred background, uses the principle of shallow depth of field.

The scene is deeply influenced by two factors: f value, which is the aperture size of the same machine; focal distance

The larger the aperture, the smaller the F value and the smaller the depth of field. The longer the focal length, the smaller the depth of field, and vice versa.

In telephoto, the depth of the scene, if you want to get a large depth of field, you must narrow the aperture and increase the F value.

Use the aperture to control the depth of field, so that the theme is clear and the photos taken are clear.

shutter

Make sure the shutter speed is high enough to get a clear picture.

Because when shooting, hand shake, fuselage shake, tripod shake, and even mechanical vibration caused by reflector will blur the picture due to movement. If the shutter speed is fast enough, the influence of these actions on the picture can be reduced.

Safety shutter speed = 1/ (current number of focal segments+10)

In addition, if the subject is moving and the shutter speed is fast, the moving object can be fixed without motion blur.
