How to take clearer photos with a SLR camera?

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.

SLR cameras (SLR cameras) are also called SLR cameras. Refers to a camera that uses a single lens, through which light shines on the reflector and takes a view through reflection.

The so-called "single lens" means that the photographic exposure light path and the framing light path share a lens, unlike the paraxial camera or the double-reflex camera, the framing light path has an independent lens.

"Reflection" means that a plane mirror in the camera separates the two light paths: when the mirror falls during framing, it reflects the light of the lens to the pentaprism and then to the framing window; When shooting, lift the reflector quickly, and the light can shine on the film or photosensitive element CMOS or CCD.
