Photography depth of field three elements of the interpretation

On top of the Digital Camera Battery mountain shooting wide when the earth, the photographer often will use small aperture, makes the picture from the most distant to recent place are clear imaging, and focus on the branches and leaves, flowers, trees and other single subjects, main body is clear, the background falsified. At this time the scenery before and after subjects are still a clear range, the range called the depth of field. In the scenery photography, depth of field control is one of the common shooting techniques. In the focal length of the lens, the photography distance and composition all don't change, adjusting aperture can control the picture of the depth of field. The greater the aperture, the shallow depth of field, the effect of the more obvious background melt. Instead, the smaller the aperture, the deeper the depth of field, the clearer background.

In fact, of the Nikon en-el1 battery depth of field is made up of three factors of the joint decision. The three factors are respectively the focal length of the lens, shooting distance and the size of the aperture. Each factor to the change of the depth of field can play a vital role. So if you want to adjust depth of field, can adjust the three factors of a certain or their combination.

Lens is inversely proportional to the Nikon en-el10 battery focal length and depth of field, the premise condition is shooting distance and aperture size unchanged. Shooting distance and aperture size on the influence of the depth of field respectively in two other factors don't become premise. Large aperture lenses advantage is: as the focal length of the lens and shooting distance in many cases is difficult to adjustment.
