What does the f on the camera mean?

F refers to the aperture value of the lens. Aperture refers to the maximum aperture or diameter of the convex surface in the lens, which determines the light transmission ability of the lens. The larger the aperture value, the larger the aperture through which light passes, and the more light enters the camera, and the photos taken will be brighter. Usually, the smaller the F value, the larger the aperture, and the stronger the light transmission ability of the camera, the easier it is to take clear and layered photos.

How to set the aperture value f on the camera?

When the camera works in aperture priority mode, we can manually set the aperture value f of the lens. Usually, when we choose the aperture value f, we need to determine the shooting scene and the required effect, and adjust the aperture size as needed. For example, shooting scenery and outdoor environment requires a large depth of field, so a large aperture value f (such as f/9) is usually selected, so that the front and rear scenes can be clearly presented in the photo at the same time; While shooting portraits or other close-ups, you need a smaller aperture value f (such as f/8) to blur the background and highlight the subject.

What effect does the aperture value f have on camera shooting?

The aperture value f affects the quality and effect of photos taken by the camera. When choosing the F value, besides the depth of field to be shot, the aperture value F also determines the brightness of the picture and the ambiguity of the background. Usually, under good lighting conditions, a small aperture value f (such as f/8) can produce a shallow depth of field and a soft background, and the photos taken will be more beautiful and soft. In low light environment, a larger aperture value f (such as f/4) can let more light into the lens, thus making the photos brighter and clearer, which is commonly used when shooting night scenes or cloudy days.
