How can I take a clear picture of the scenery?

In order to make the far and near scenes of photos clear, it is necessary to adjust the depth of field to make it larger.

Depth of field is related to aperture, focal length and shooting distance. To adjust the depth of field, we must adjust these three elements.

1, select a small aperture: the smaller the aperture, the wider the depth of field.

Therefore, in order to make the far and near scenes in the photo clear, you can consider choosing a small aperture. The smaller the aperture, the greater the depth of field and the larger the clear range, which can achieve the expected purpose.

2. Choose a wide-angle lens or wide-angle end: the smaller the focal length, the wider the depth of field.

The background and foreground are very clear, so you can choose the wide-angle lens or the wide-angle end of the zoom lens to shoot, and you can also get the effect that the far and near scenes are very clear.

3, long-distance shooting:

The shooting distance is longer, the proportion of far and near scenes in the framing picture becomes smaller, and the background is clear.

4. Front focusing of1/3: The front and back of focusing are divided into foreground depth of field and back depth of field, and back depth of field =2 times the foreground depth of field.

Therefore, focusing on the front of the camera screen 1/3 can maximize the depth of field, sometimes resulting in hyperfocal distance. At this time, the clear range of background and foreground will be wider, so far and near scenes will be imaged clearly.

Extended data:

In addition to aperture, distance and focal length, the photographer's requirements for blur circle, that is, the allowable blur circle size, are also closely related to the depth of field. The allowable fuzzy circle is large, which is also closely related to the depth of field.

When the allowable fuzzy circle is large, the depth of field will be larger if the photo is made by contact printing or small magnification; When the allowable blur circle is small, the depth of field will be smaller if the photo is taken at high magnification.

Aperture, camera distance, lens focal length and the size of allowable blur circle have relative effects on depth of field, that is, when three of these four factors are the same, the other factor has an effect on depth of field. Otherwise, these "laws" may not be established.

For example, if the focal length of the lens is 75mm and the focus is 2m, the depth of field of f 16 is 1.5-3. 1m, and if the focus is 5m, the depth of field of f11m.. The depth of field of a small aperture (f 16) is 1.6m, while that of a large aperture (f 1 1) is 8m, which is due to different camera distances.
