Does the aperture size of the camera have a great influence on the image quality?

1. The larger the aperture, the closer the subject is. If the subject is near, the distant scenery is invisible or unclear. Change terminology to blur background;

2. The smaller the aperture, the farther the object is photographed. If the subject is far away, the nearby objects can't be seen clearly. In other words, it is called: blurring the prospect;

3. The larger the aperture, the greater the light input, which can shorten the shutter time and capture the moving moment; It can also reduce ISO and improve image quality;
