camera aperture的意思|示意

Camera aperture is a term used to describe the opening of the lens in a camera. It is the size of the opening that determines how much light is able to pass through to the image sensor. The size of the aperture is measured in terms of f-numbers such as f-2, f-4, f-8 and so on. The smaller the f-number, the larger the opening and the more light that will pass through.

Aperture is best used in combination with shutter speed. For example, if you use a slow shutter speed, then a larger aperture will let more light in to compensate. Inversely, if you are using a faster shutter speed, then a smaller aperture can be used to limit the amount of light.

Aperture is also used to control the depth of field in a photograph. A larger f-number will cause the background to be more in focus whereas a smaller f-number will create a shallow depth of field and make the background appear blurred. This is often used to draw attention to the main subject in a photograph.

In conclusion, camera aperture is an important setting to learn and understand in order to become a better photographer. The combination of shutter speed and aperture will help to create stunning images that capture light in the desired way.
