What is the function of aperture? Control depth of field

When the aperture increases, the depth of field decreases, and when the aperture decreases, the depth of field increases. How to adjust the aperture depends on what effect the photographer wants.

Controlling exposure When the aperture is wide, the exposure will be large. Generally, when shooting at night, the photographer will turn up the aperture. The aperture is reduced, the exposure is small, and the photos taken are more natural.

Controlling pixels When the aperture increases, the imaging of the camera will become worse. The larger the aperture, the more blurred the photos, while the smaller the aperture, the more natural the imaging.

What is the function of shutter? The shutter controls the exposure, which can also be said to be the last step to complete imaging. When the shutter of the camera is pressed, it will form an image.
