Influence of aperture and exposure change

The change of aperture will lead to the change of depth of field. The larger the aperture, the smaller the depth of field, which is easy to produce the effect of blurred background. So in order to get a blurred background, a large aperture is needed. And sometimes, in order to get better image quality, we also reduce the aperture instead of using the maximum aperture.

Of course, different exposure times will be different. The shorter the exposure time, the easier it is to capture the instantaneous effect. For example, sports photography needs to shorten the exposure time; It takes a long time to expose the vehicle lighting route at night.

So we need to change the combination of aperture and shutter according to the actual situation, so as to apply it to practice.

The P file, A file and S file of the camera are all set for practical application.
