What does photography f2.8 mean?

F8 refers to the aperture size of the camera lens, which is one of the factors that affect the depth of field of a photo. F8 has a large aperture, which allows more light to enter the camera and makes the background of the photo more blurred. Very suitable for taking clear close-up photos of portraits, animals and so on. However, f8 will show a shallow depth of field when shooting in the distant view. In this case, photographers need to pay special attention to the choice of focal length and the accuracy of camera focusing.

F8 aperture is large, suitable for shooting in dark or low light environment. For example, when shooting indoors or at night, the ISO value of the camera can be reduced, and noise and color distortion can be reduced. In addition, f8 is especially suitable for shooting close-up subjects such as portraits and animals, which can clearly present the outline of the subject, and the blurred background makes the subject more prominent.

When shooting with f8, we should understand the depth phenomenon of the scene caused by fully opening the aperture, and pay attention to the shooting distance. In addition, f8 needs to reasonably choose the focal length and focusing mode when shooting the distant view, and try to use other photography skills such as HDR shooting, picture segmentation, filters and other technical means to show a more unique shooting effect. In a word, although f8 has many advantages in photography, it also needs photographers to actively explore and keep trying while cherishing opportunities, so as to achieve better shooting results.
